hazelcast_带弹簧的Hazelcast分布式执行

發布時間：2023/12/3 编程问答 30 豆豆

生活随笔收集整理的這篇文章主要介紹了 hazelcast_带弹簧的Hazelcast分布式执行小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

hazelcast

ExecutorService功能是Java 5附帶的，位于java.util.concurrent包中。它擴展了Executor接口，并提供了線程池功能來執行異步簡短任務。建議使用Java Executor服務類型來查看基本的ExecutorService實現。

ThreadPoolExecutor也是ExecutorService接口的非常有用的實現。它擴展了AbstractExecutorService，提供了ExecutorService執行方法的默認實現。當執行大量異步任務時，它可提供改進的性能，并維護基本統計信息，例如已完成任務的數量。

還建議如何使用Spring開發和監視線程池服務，以研究如何開發和監視線程池服務。

到目前為止，我們剛剛談到了“分布式執行器服務”的實現。讓我們還調查分布式執行器服務。

Hazelcast Distributed Executor Service功能是java.util.concurrent.ExecutorService的分布式實現。它允許在集群中執行業務邏輯。有四種替代方法可以實現它：

可以在選擇的特定群集成員上執行該邏輯。
邏輯可以在擁有所選密鑰的成員上執行。
該邏輯可以在Hazelcast將選擇的成員上執行。
該邏輯可以在全部或部分集群成員上執行。

本文介紹如何通過Hazelcast和Spring開發分布式執行器服務。

二手技術：

JDK 1.7.0_09
Spring3.1.3
榛子堡2.4
Maven的3.0.4

步驟1：建立已完成的專案

創建一個Maven項目，如下所示。（可以使用Maven或IDE插件創建）。

步驟2：圖書館

首先，將Spring依賴項添加到Maven的pom.xml中

<properties><spring.version>3.1.3.RELEASE</spring.version><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding></properties><dependencies><dependency><groupId>org.springframework</groupId><artifactId>spring-core</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-context</artifactId><version>${spring.version}</version></dependency><dependency><groupId>com.hazelcast</groupId><artifactId>hazelcast-all</artifactId><version>2.4</version></dependency><dependency><groupId>log4j</groupId><artifactId>log4j</artifactId><version>1.2.16</version></dependency></dependencies>

maven-compiler-plugin （Maven插件）用于使用JDK 1.7編譯項目

<plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-compiler-plugin</artifactId><version>3.0</version><configuration><source>1.7</source><target>1.7</target></configuration></plugin>

maven-shade-plugin （Maven插件）可用于創建runnable-jar

<plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-shade-plugin</artifactId><version>2.0</version><executions><execution><phase>package</phase><goals><goal>shade</goal></goals><configuration><transformers><transformerimplementation='org.apache.maven.plugins.shade.resource. ManifestResourceTransformer'><mainClass>com.onlinetechvision.exe.Application</mainClass></transformer><transformerimplementation='org.apache.maven.plugins.shade.resource. AppendingTransformer'><resource>META-INF/spring.handlers</resource></transformer><transformerimplementation='org.apache.maven.plugins.shade.resource. AppendingTransformer'><resource>META-INF/spring.schemas</resource></transformer></transformers></configuration></execution></executions></plugin>

步驟3：建立客戶關系

創建了一個新的Customer bean。該bean將分布在OTV集群中的兩個節點之間。在以下示例中，所有定義的屬性（id，名稱和姓氏）的類型均為String，并且已實現標準java.io.Serializable接口以進行序列化。如果使用自定義或第三方對象類型，則可以實現com.hazelcast.nio.DataSerializable接口以獲得更好的序列化性能。

package com.onlinetechvision.customer;import java.io.Serializable;/*** Customer Bean.** @author onlinetechvision.com* @since 27 Nov 2012* @version 1.0.0**/ public class Customer implements Serializable {private static final long serialVersionUID = 1856862670651243395L;private String id;private String name;private String surname;public String getId() {return id;}public void setId(String id) {this.id = id;}public String getName() {return name;}public void setName(String name) {this.name = name;}public String getSurname() {return surname;}public void setSurname(String surname) {this.surname = surname;}@Overridepublic int hashCode() {final int prime = 31;int result = 1;result = prime * result + ((id == null) ? 0 : id.hashCode());result = prime * result + ((name == null) ? 0 : name.hashCode());result = prime * result + ((surname == null) ? 0 : surname.hashCode());return result;}@Overridepublic boolean equals(Object obj) {if (this == obj)return true;if (obj == null)return false;if (getClass() != obj.getClass())return false;Customer other = (Customer) obj;if (id == null) {if (other.id != null)return false;} else if (!id.equals(other.id))return false;if (name == null) {if (other.name != null)return false;} else if (!name.equals(other.name))return false;if (surname == null) {if (other.surname != null)return false;} else if (!surname.equals(other.surname))return false;return true;}@Overridepublic String toString() {return 'Customer [id=' + id + ', name=' + name + ', surname=' + surname + ']';}}

步驟4：建立ICacheService介面

為服務層創建了一個新的ICacheService接口，以公開緩存功能。

package com.onlinetechvision.cache.srv;import com.hazelcast.core.IMap; import com.onlinetechvision.customer.Customer;/*** A new ICacheService Interface is created for service layer to expose cache functionality.** @author onlinetechvision.com* @since 27 Nov 2012* @version 1.0.0**/ public interface ICacheService {/*** Adds Customer entries to cache** @param String key* @param Customer customer**/void addToCache(String key, Customer customer);/*** Deletes Customer entries from cache** @param String key**/void deleteFromCache(String key);/*** Gets Customer cache** @return IMap Coherence named cache*/IMap<String, Customer> getCache(); }

步驟5：創建CacheService實現

CacheService是ICacheService接口的實現。

package com.onlinetechvision.cache.srv;import com.hazelcast.core.IMap; import com.onlinetechvision.customer.Customer; import com.onlinetechvision.test.listener.CustomerEntryListener;/*** CacheService Class is implementation of ICacheService Interface.** @author onlinetechvision.com* @since 27 Nov 2012* @version 1.0.0**/ public class CacheService implements ICacheService {private IMap<String, Customer> customerMap;/*** Constructor of CacheService** @param IMap customerMap**/@SuppressWarnings('unchecked')public CacheService(IMap<String, Customer> customerMap) {setCustomerMap(customerMap);getCustomerMap().addEntryListener(new CustomerEntryListener(), true);}/*** Adds Customer entries to cache** @param String key* @param Customer customer**/@Overridepublic void addToCache(String key, Customer customer) {getCustomerMap().put(key, customer);}/*** Deletes Customer entries from cache** @param String key**/@Overridepublic void deleteFromCache(String key) {getCustomerMap().remove(key);}/*** Gets Customer cache** @return IMap Coherence named cache*/@Overridepublic IMap<String, Customer> getCache() {return getCustomerMap();}public IMap<String, Customer> getCustomerMap() {return customerMap;}public void setCustomerMap(IMap<String, Customer> customerMap) {this.customerMap = customerMap;}}

步驟6：建立IDistributedExecutorService接口

為服務層創建了一個新的IDistributedExecutorService接口，以公開分布式執行功能。

package com.onlinetechvision.executor.srv;import java.util.Collection; import java.util.Set; import java.util.concurrent.Callable; import java.util.concurrent.ExecutionException;import com.hazelcast.core.Member;/*** A new IDistributedExecutorService Interface is created for service layer to expose distributed execution functionality.** @author onlinetechvision.com* @since 27 Nov 2012* @version 1.0.0**/ public interface IDistributedExecutorService {/*** Executes the callable object on stated member** @param Callable callable* @param Member member* @throws InterruptedException* @throws ExecutionException**/String executeOnStatedMember(Callable<String> callable, Member member) throws InterruptedException, ExecutionException;/*** Executes the callable object on member owning the key** @param Callable callable* @param Object key* @throws InterruptedException* @throws ExecutionException**/String executeOnTheMemberOwningTheKey(Callable<String> callable, Object key) throws InterruptedException, ExecutionException;/*** Executes the callable object on any member** @param Callable callable* @throws InterruptedException* @throws ExecutionException**/String executeOnAnyMember(Callable<String> callable) throws InterruptedException, ExecutionException;/*** Executes the callable object on all members** @param Callable callable* @param Set all members* @throws InterruptedException* @throws ExecutionException**/Collection<String> executeOnMembers(Callable<String> callable, Set<Member> members) throws InterruptedException, ExecutionException; }

步驟7：創建DistributedExecutorService實現

DistributedExecutorService是IDistributedExecutorService接口的實現。

package com.onlinetechvision.executor.srv;import java.util.Collection; import java.util.Set; import java.util.concurrent.Callable; import java.util.concurrent.ExecutionException; import java.util.concurrent.ExecutorService; import java.util.concurrent.Future; import java.util.concurrent.FutureTask;import org.apache.log4j.Logger;import com.hazelcast.core.DistributedTask; import com.hazelcast.core.Member; import com.hazelcast.core.MultiTask;/*** DistributedExecutorService Class is implementation of IDistributedExecutorService Interface.** @author onlinetechvision.com* @since 27 Nov 2012* @version 1.0.0**/ public class DistributedExecutorService implements IDistributedExecutorService {private static final Logger logger = Logger.getLogger(DistributedExecutorService.class);private ExecutorService hazelcastDistributedExecutorService;/*** Executes the callable object on stated member** @param Callable callable* @param Member member* @throws InterruptedException* @throws ExecutionException**/@SuppressWarnings('unchecked')public String executeOnStatedMember(Callable<String> callable, Member member) throws InterruptedException, ExecutionException {logger.debug('Method executeOnStatedMember is called...');ExecutorService executorService = getHazelcastDistributedExecutorService();FutureTask<String> task = (FutureTask<String>) executorService.submit( new DistributedTask<String>(callable, member));String result = task.get();logger.debug('Result of method executeOnStatedMember is : ' + result);return result;}/*** Executes the callable object on member owning the key** @param Callable callable* @param Object key* @throws InterruptedException* @throws ExecutionException**/@SuppressWarnings('unchecked')public String executeOnTheMemberOwningTheKey(Callable<String> callable, Object key) throws InterruptedException, ExecutionException {logger.debug('Method executeOnTheMemberOwningTheKey is called...');ExecutorService executorService = getHazelcastDistributedExecutorService();FutureTask<String> task = (FutureTask<String>) executorService.submit(new DistributedTask<String>(callable, key));String result = task.get();logger.debug('Result of method executeOnTheMemberOwningTheKey is : ' + result);return result;}/*** Executes the callable object on any member** @param Callable callable* @throws InterruptedException* @throws ExecutionException**/public String executeOnAnyMember(Callable<String> callable) throws InterruptedException, ExecutionException {logger.debug('Method executeOnAnyMember is called...');ExecutorService executorService = getHazelcastDistributedExecutorService();Future<String> task = executorService.submit(callable);String result = task.get();logger.debug('Result of method executeOnAnyMember is : ' + result);return result;}/*** Executes the callable object on all members** @param Callable callable* @param Set all members* @throws InterruptedException* @throws ExecutionException**/public Collection<String> executeOnMembers(Callable<String> callable, Set<Member> members) throws ExecutionException, InterruptedException {logger.debug('Method executeOnMembers is called...');MultiTask<String> task = new MultiTask<String>(callable, members);ExecutorService executorService = getHazelcastDistributedExecutorService();executorService.execute(task);Collection<String> results = task.get();logger.debug('Result of method executeOnMembers is : ' + results.toString());return results;}public ExecutorService getHazelcastDistributedExecutorService() {return hazelcastDistributedExecutorService;}public void setHazelcastDistributedExecutorService(ExecutorService hazelcastDistributedExecutorService) {this.hazelcastDistributedExecutorService = hazelcastDistributedExecutorService;}}

步驟8：建立TestCallable類別

TestCallable類顯示要執行的業務邏輯。

集群的第一個成員的TestCallable任務：

package com.onlinetechvision.task;import java.io.Serializable; import java.util.concurrent.Callable;/*** TestCallable Class shows business logic to be executed.** @author onlinetechvision.com* @since 27 Nov 2012* @version 1.0.0**/ public class TestCallable implements Callable<String>, Serializable{private static final long serialVersionUID = -1839169907337151877L;/*** Computes a result, or throws an exception if unable to do so.** @return String computed result* @throws Exception if unable to compute a result*/public String call() throws Exception {return 'First Member' s TestCallable Task is called...';}}

集群第二個成員的TestCallable任務：

步驟9：創建AnotherAvailableMemberNotFoundException類

當找不到另一個可用成員時，將引發AnotherAvailableMemberNotFoundException 。為避免此異常，應在第二個節點之前啟動第一個節點。

package com.onlinetechvision.exception;/*** AnotherAvailableMemberNotFoundException is thrown when another available member is not found.* To avoid this exception, first node should be started before the second node.** @author onlinetechvision.com* @since 27 Nov 2012* @version 1.0.0**/ public class AnotherAvailableMemberNotFoundException extends Exception {private static final long serialVersionUID = -3954360266393077645L;/*** Constructor of AnotherAvailableMemberNotFoundException** @param String Exception message**/public AnotherAvailableMemberNotFoundException(String message) {super(message);}}

步驟10：建立CustomerEntryListener類別

CustomerEntryListener類偵聽命名的緩存對象上的條目更改。

package com.onlinetechvision.test.listener;import com.hazelcast.core.EntryEvent; import com.hazelcast.core.EntryListener;/*** CustomerEntryListener Class listens entry changes on named cache object.** @author onlinetechvision.com* @since 27 Nov 2012* @version 1.0.0**/ @SuppressWarnings('rawtypes') public class CustomerEntryListener implements EntryListener {/*** Invoked when an entry is added.** @param EntryEvent**/public void entryAdded(EntryEvent ee) {System.out.println('EntryAdded... Member : ' + ee.getMember() + ', Key : '+ee.getKey()+', OldValue : '+ee.getOldValue()+', NewValue : '+ee.getValue());}/*** Invoked when an entry is removed.** @param EntryEvent**/public void entryRemoved(EntryEvent ee) {System.out.println('EntryRemoved... Member : ' + ee.getMember() + ', Key : '+ee.getKey()+', OldValue : '+ee.getOldValue()+', NewValue : '+ee.getValue());}/*** Invoked when an entry is evicted.** @param EntryEvent**/public void entryEvicted(EntryEvent ee) {} /*** Invoked when an entry is updated.** @param EntryEvent**/public void entryUpdated(EntryEvent ee) {}}

步驟11：創建入門類

入門類會加載客戶以緩存和執行分布式任務。

集群的第一個成員的入門類：

package com.onlinetechvision.exe;import com.onlinetechvision.cache.srv.ICacheService; import com.onlinetechvision.customer.Customer;/*** Starter Class loads Customers to cache and executes distributed tasks.** @author onlinetechvision.com* @since 27 Nov 2012* @version 1.0.0**/ public class Starter {private ICacheService cacheService;/*** Loads cache and executes the tasks**/public void start() {loadCacheForFirstMember();}/*** Loads Customers to cache**/public void loadCacheForFirstMember() {Customer firstCustomer = new Customer();firstCustomer.setId('1');firstCustomer.setName('Jodie');firstCustomer.setSurname('Foster');Customer secondCustomer = new Customer();secondCustomer.setId('2');secondCustomer.setName('Kate');secondCustomer.setSurname('Winslet');getCacheService().addToCache(firstCustomer.getId(), firstCustomer);getCacheService().addToCache(secondCustomer.getId(), secondCustomer);}public ICacheService getCacheService() {return cacheService;}public void setCacheService(ICacheService cacheService) {this.cacheService = cacheService;}}

集群第二個成員的入門類：

package com.onlinetechvision.exe;import java.util.Set; import java.util.concurrent.ExecutionException;import com.hazelcast.core.Hazelcast; import com.hazelcast.core.HazelcastInstance; import com.hazelcast.core.Member; import com.onlinetechvision.cache.srv.ICacheService; import com.onlinetechvision.customer.Customer; import com.onlinetechvision.exception.AnotherAvailableMemberNotFoundException; import com.onlinetechvision.executor.srv.IDistributedExecutorService; import com.onlinetechvision.task.TestCallable;/*** Starter Class loads Customers to cache and executes distributed tasks.** @author onlinetechvision.com* @since 27 Nov 2012* @version 1.0.0**/ public class Starter {private String hazelcastInstanceName;private Hazelcast hazelcast;private IDistributedExecutorService distributedExecutorService;private ICacheService cacheService;/*** Loads cache and executes the tasks**/public void start() {loadCache();executeTasks();}/*** Loads Customers to cache**/public void loadCache() {Customer firstCustomer = new Customer();firstCustomer.setId('3');firstCustomer.setName('Bruce');firstCustomer.setSurname('Willis');Customer secondCustomer = new Customer();secondCustomer.setId('4');secondCustomer.setName('Colin');secondCustomer.setSurname('Farrell');getCacheService().addToCache(firstCustomer.getId(), firstCustomer);getCacheService().addToCache(secondCustomer.getId(), secondCustomer);}/*** Executes Tasks**/public void executeTasks() {try {getDistributedExecutorService().executeOnStatedMember(new TestCallable(), getAnotherMember());getDistributedExecutorService().executeOnTheMemberOwningTheKey(new TestCallable(), '3');getDistributedExecutorService().executeOnAnyMember(new TestCallable());getDistributedExecutorService().executeOnMembers(new TestCallable(), getAllMembers());} catch (InterruptedException | ExecutionException | AnotherAvailableMemberNotFoundException e) {e.printStackTrace();}}/*** Gets cluster members** @return Set<Member> Set of Cluster Members**/private Set<Member> getAllMembers() {Set<Member> members = getHazelcastLocalInstance().getCluster().getMembers();return members;}/*** Gets an another member of cluster** @return Member Another Member of Cluster* @throws AnotherAvailableMemberNotFoundException An Another Available Member can not found exception*/private Member getAnotherMember() throws AnotherAvailableMemberNotFoundException {Set<Member> members = getAllMembers();for(Member member : members) {if(!member.localMember()) {return member;}}throw new AnotherAvailableMemberNotFoundException('No Other Available Member on the cluster. Please be aware that all members are active on the cluster');}/*** Gets Hazelcast local instance** @return HazelcastInstance Hazelcast local instance*/@SuppressWarnings('static-access')private HazelcastInstance getHazelcastLocalInstance() {HazelcastInstance instance = getHazelcast().getHazelcastInstanceByName(getHazelcastInstanceName());return instance;}public String getHazelcastInstanceName() {return hazelcastInstanceName;}public void setHazelcastInstanceName(String hazelcastInstanceName) {this.hazelcastInstanceName = hazelcastInstanceName;}public Hazelcast getHazelcast() {return hazelcast;}public void setHazelcast(Hazelcast hazelcast) {this.hazelcast = hazelcast;}public IDistributedExecutorService getDistributedExecutorService() {return distributedExecutorService;}public void setDistributedExecutorService(IDistributedExecutorService distributedExecutorService) {this.distributedExecutorService = distributedExecutorService;}public ICacheService getCacheService() {return cacheService;}public void setCacheService(ICacheService cacheService) {this.cacheService = cacheService;}}

步驟12：創建hazelcast-config.properties文件

hazelcast-config.properties文件顯示集群成員的屬性。

第一會員屬性：

hz.instance.name = OTVInstance1hz.group.name = dev hz.group.password = devhz.management.center.enabled = true hz.management.center.url = http://localhost:8080/mancenterhz.network.port = 5701 hz.network.port.auto.increment = falsehz.tcp.ip.enabled = truehz.members = 192.168.1.32hz.executor.service.core.pool.size = 2 hz.executor.service.max.pool.size = 30 hz.executor.service.keep.alive.seconds = 30hz.map.backup.count=2 hz.map.max.size=0 hz.map.eviction.percentage=30 hz.map.read.backup.data=true hz.map.cache.value=true hz.map.eviction.policy=NONE hz.map.merge.policy=hz.ADD_NEW_ENTRY

第二成員屬性：

hz.instance.name = OTVInstance2hz.group.name = dev hz.group.password = devhz.management.center.enabled = true hz.management.center.url = http://localhost:8080/mancenterhz.network.port = 5702 hz.network.port.auto.increment = falsehz.tcp.ip.enabled = truehz.members = 192.168.1.32hz.executor.service.core.pool.size = 2 hz.executor.service.max.pool.size = 30 hz.executor.service.keep.alive.seconds = 30hz.map.backup.count=2 hz.map.max.size=0 hz.map.eviction.percentage=30 hz.map.read.backup.data=true hz.map.cache.value=true hz.map.eviction.policy=NONE hz.map.merge.policy=hz.ADD_NEW_ENTRY

步驟13：創建applicationContext-hazelcast.xml

創建Spring Hazelcast配置文件applicationContext-hazelcast.xml ，并配置Hazelcast分布式執行器服務和Hazelcast實例。

<beans xmlns='http://www.springframework.org/schema/beans'xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'xmlns:hz='http://www.hazelcast.com/schema/spring'xsi:schemaLocation='http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans-3.0.xsdhttp://www.hazelcast.com/schema/springhttp://www.hazelcast.com/schema/spring/hazelcast-spring-2.4.xsd'><hz:map id='customerMap' name='customerMap' instance-ref='instance'/><hz:executorService id='hazelcastDistributedExecutorService' instance-ref='instance' name='hazelcastDistributedExecutorService' /><hz:hazelcast id='instance'><hz:config><hz:instance-name>${hz.instance.name}</hz:instance-name><hz:group name='${hz.group.name}' password='${hz.group.password}'/> <hz:management-center enabled='${hz.management.center.enabled}' url='${hz.management.center.url}'/><hz:network port='${hz.network.port}' port-auto-increment='${hz.network.port.auto.increment}'><hz:join><hz:tcp-ip enabled='${hz.tcp.ip.enabled}'><hz:members>${hz.members}</hz:members></hz:tcp-ip></hz:join></hz:network><hz:executor-service name='executorService'core-pool-size='${hz.executor.service.core.pool.size}'max-pool-size='${hz.executor.service.max.pool.size}'keep-alive-seconds='${hz.executor.service.keep.alive.seconds}'/><hz:map name='map'backup-count='${hz.map.backup.count}'max-size='${hz.map.max.size}'eviction-percentage='${hz.map.eviction.percentage}'read-backup-data='${hz.map.read.backup.data}'cache-value='${hz.map.cache.value}'eviction-policy='${hz.map.eviction.policy}'merge-policy='${hz.map.merge.policy}' /></hz:config></hz:hazelcast> </beans>

步驟14：創建applicationContext.xml

Spring配置文件applicationContext.xml已創建。

步驟15：創建應用程序類

創建應用程序類以運行應用程序。

package com.onlinetechvision.exe;import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext;/*** Application class starts the application** @author onlinetechvision.com* @since 27 Nov 2012* @version 1.0.0**/ public class Application {/*** Starts the application** @param String[] args**/public static void main(String[] args) {ApplicationContext context = new ClassPathXmlApplicationContext('applicationContext.xml');Starter starter = (Starter) context.getBean('starter');starter.start();}}

步驟16：建立專案

生成OTV_Spring_Hazelcast_DistributedExecution項目后，將創建OTV_Spring_Hazelcast_DistributedExecution-0.0.1-SNAPSHOT.jar 。

重要說明：群集的成員具有不同的Coherence配置，因此應為每個成員分別構建項目。

步驟17：與HAZELCAST管理中心集成

通過Hazelcast Management Center，可以監視和管理群集中的節點。

customerMap擁有的實體和備份計數可以通過“映射內存數據表”查看。我們通過customerMap分發了4個條目，如下所示：

可以通過地圖瀏覽器查看示例鍵和值：

添加了第一個條目：

添加了第三項：

hazelcastDistributedExecutor服務詳細信息可以通過“ Executors”選項卡查看。我們已經對第一個成員執行了3個任務，對第二個成員執行了2個任務，如下所示：

步驟18：通過啟動集群成員來運行項目

在集群的成員上運行OTV_Spring_Hazelcast_DistributedExecution-0.0.1-SNAPSHOT.jar文件之后，將顯示以下控制臺輸出日志：

第一成員控制臺輸出：
