新換環境,又有新東西可以學習了,哈皮! 抽空學習之余看了一下redis,個人對Springmvc的愛是忠貞不渝,所以整理了一下Springmvc整合redis的環境搭建.分享學習.

第一步?:?創建?maven?項目?:

實例pom.xml內容如下

<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"><modelVersion>4.0.0</modelVersion><packaging>war</packaging><name>orm-bae</name><groupId>com.orm</groupId><artifactId>orm-bae</artifactId><version>0.0.1-SNAPSHOT</version><properties> <org.springframework.version>3.0.5.RELEASE</org.springframework.version><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> </properties> <dependencies><!-- config junit jar --><dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.8.2</version> <scope>test</scope> </dependency> <!-- config redis data and client jar--> <dependency> <groupId>org.springframework.data</groupId> <artifactId>spring-data-redis</artifactId> <version>1.0.2.RELEASE</version> </dependency> <dependency> <groupId>redis.clients</groupId> <artifactId>jedis</artifactId> <version>2.1.0</version> </dependency><!-- config need jar --><dependency><groupId>commons-lang</groupId><artifactId>commons-lang</artifactId><version>2.6</version></dependency><dependency><groupId>org.apache.geronimo.specs</groupId><artifactId>geronimo-servlet_3.0_spec</artifactId><version>1.0</version></dependency><!-- cofig spring jar --><dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${org.springframework.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-expression</artifactId> <version>${org.springframework.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> <version>${org.springframework.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> <version>${org.springframework.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${org.springframework.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> <version>${org.springframework.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>${org.springframework.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>${org.springframework.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-orm</artifactId> <version>${org.springframework.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-oxm</artifactId> <version>${org.springframework.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>${org.springframework.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${org.springframework.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc-portlet</artifactId> <version>${org.springframework.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>${org.springframework.version}</version> <scope>test</scope> </dependency> </dependencies><build><resources><resource><directory>/src/main/resources</directory><filtering>true</filtering></resource></resources></build> </project>

第二步?:?配置文件整合

Web.xml文件配置

<?xml version="1.0" encoding="UTF-8"?> <web-app version="2.4"xmlns="http://java.sun.com/xml/ns/j2ee"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><context-param><param-name>contextConfigLocation</param-name><param-value>/WEB-INF/context/spring-context.xml</param-value></context-param><!-- Spring字符集過濾器 --><filter><filter-name>SpringEncodingFilter</filter-name><filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class><init-param><param-name>encoding</param-name><param-value>UTF-8</param-value></init-param><init-param><param-name>forceEncoding</param-name><param-value>true</param-value></init-param></filter><filter-mapping><filter-name>SpringEncodingFilter</filter-name><url-pattern>/*</url-pattern></filter-mapping><servlet><servlet-name>mvc</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><init-param><param-name>contextConfigLocation</param-name><param-value>/WEB-INF/context/spring-mvc.xml</param-value></init-param><load-on-startup>2</load-on-startup></servlet><servlet-mapping><servlet-name>mvc</servlet-name><url-pattern>/</url-pattern></servlet-mapping><welcome-file-list><welcome-file>index.jsp</welcome-file></welcome-file-list></web-app>

spring-context.xml內容

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context"xmlns:util="http://www.springframework.org/schema/util"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.0.xsd"><!-- 激活@Controller模式 --><mvc:annotation-driven /><!-- 對包中的所有類進行掃描，以完成Bean創建和自動依賴注入的功能 需要更改 --><context:component-scan base-package="com.pudp.bae.*" /><!-- 引入同文件夾下的redis屬性配置文件 --><import resource="redis-context.xml"/></beans>

redis-context.xml內容

<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:p="http://www.springframework.org/schema/p" xmlns:tx="http://www.springframework.org/schema/tx"xmlns:context="http://www.springframework.org/schema/context"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsdhttp://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context-3.0.xsd"><!-- scanner redis properties --> <context:property-placeholder location="/WEB-INF/property/redis.properties" /><bean id="poolConfig" class="redis.clients.jedis.JedisPoolConfig"> <property name="maxIdle" value="${redis.maxIdle}" /> <property name="maxActive" value="${redis.maxActive}" /> <property name="maxWait" value="${redis.maxWait}" /> <property name="testOnBorrow" value="${redis.testOnBorrow}" /> </bean> <bean id="connectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory" p:host-name="${redis.host}" p:port="${redis.port}" p:password="${redis.pass}" p:pool-config-ref="poolConfig"/> <bean id="redisTemplate" class="org.springframework.data.redis.core.StringRedisTemplate"> <property name="connectionFactory" ref="connectionFactory" /> </bean> </beans>

Redis.properties文件內容

# Redis settings #redis.host=192.168.20.101 #redis.port=6380 #redis.pass=foobared redis.host=127.0.0.1 redis.port=6379 redis.pass=redis.maxIdle=300 redis.maxActive=600 redis.maxWait=1000 redis.testOnBorrow=true

第三步?:Springmvc?對?Redis?的支持與實例應用?.

實例對象

package com.pudp.bae.model;import com.pudp.bae.base.BaseModel;public class Member extends BaseModel{/*** */private static final long serialVersionUID = -1959528436584592183L;private String id;private String nickname;public Member(){}public Member(String id, String nickname){this.setId(id);this.setNickname(nickname);}public String getId() {return id;}public void setId(String id) {this.id = id;}public String getNickname() {return nickname;}public void setNickname(String nickname) {this.nickname = nickname;}} View Code

Redis對象持久化操作

package com.pudp.bae.base;import java.io.Serializable;import org.springframework.beans.factory.annotation.Autowired; import org.springframework.data.redis.core.RedisTemplate; import org.springframework.data.redis.serializer.RedisSerializer;public abstract class RedisGeneratorDao<K extends Serializable, V extends Serializable> {@Autowiredprotected RedisTemplate<K,V> redisTemplate ;/** * 設置redisTemplate * @param redisTemplate the redisTemplate to set */ public void setRedisTemplate(RedisTemplate<K, V> redisTemplate) { this.redisTemplate = redisTemplate; } /** * 獲取 RedisSerializer * <br>------------------------------<br> */ protected RedisSerializer<String> getRedisSerializer() { return redisTemplate.getStringSerializer(); } }

?

redis對象操作

package com.pudp.bae.dao.redis;import java.util.ArrayList; import java.util.List;import org.springframework.dao.DataAccessException; import org.springframework.data.redis.connection.RedisConnection; import org.springframework.data.redis.core.RedisCallback; import org.springframework.data.redis.serializer.RedisSerializer; import org.springframework.stereotype.Repository; import org.springframework.util.Assert;import com.pudp.bae.base.RedisGeneratorDao; import com.pudp.bae.model.Member;/*** 參看博客 <br>* -------------------------------------------------------------------------------* * -------------------------------------------------------------------------------*/@Repository(value="memberDao") public class MemberDaoImpl extends RedisGeneratorDao<String,Member> implements MemberDao{/*** 添加對象*/@Overridepublic boolean add(final Member member) { boolean result = redisTemplate.execute(new RedisCallback<Boolean>() { public Boolean doInRedis(RedisConnection connection) throws DataAccessException { RedisSerializer<String> serializer = getRedisSerializer(); byte[] key = serializer.serialize(member.getId()); byte[] name = serializer.serialize(member.getNickname()); return connection.setNX(key, name); } }); return result; } /*** 添加集合*/@Overridepublic boolean add(final List<Member> list) {Assert.notEmpty(list); boolean result = redisTemplate.execute(new RedisCallback<Boolean>() { public Boolean doInRedis(RedisConnection connection) throws DataAccessException { RedisSerializer<String> serializer = getRedisSerializer(); for (Member member : list) { byte[] key = serializer.serialize(member.getId()); byte[] name = serializer.serialize(member.getNickname()); connection.setNX(key, name); } return true; } }, false, true); return result; } /*** 刪除對象 ,依賴key*/public void delete(String key) { List<String> list = new ArrayList<String>(); list.add(key); delete(list); } /*** 刪除集合 ,依賴key集合*/public void delete(List<String> keys) { redisTemplate.delete(keys); } /*** 修改對象 */public boolean update(final Member member) { String key = member.getId(); if (get(key) == null) { throw new NullPointerException("數據行不存在, key = " + key); } boolean result = redisTemplate.execute(new RedisCallback<Boolean>() { public Boolean doInRedis(RedisConnection connection) throws DataAccessException { RedisSerializer<String> serializer = getRedisSerializer(); byte[] key = serializer.serialize(member.getId()); byte[] name = serializer.serialize(member.getNickname()); connection.set(key, name); return true; } }); return result; } /*** 根據key獲取對象*/public Member get(final String keyId) { Member result = redisTemplate.execute(new RedisCallback<Member>() { public Member doInRedis(RedisConnection connection) throws DataAccessException { RedisSerializer<String> serializer = getRedisSerializer(); byte[] key = serializer.serialize(keyId); byte[] value = connection.get(key); if (value == null) { return null; } String nickname = serializer.deserialize(value); return new Member(keyId, nickname); } }); return result; } }

Controller實現

package com.pudp.bae.controller;import java.util.HashMap; import java.util.Map;import javax.annotation.Resource; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse;import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.ModelAttribute; import org.springframework.web.bind.annotation.PathVariable; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.servlet.ModelAndView;import com.pudp.bae.base.BaseMultiController; import com.pudp.bae.model.Member; import com.pudp.bae.service.MemberService;@Controller @RequestMapping(value="/member") public class MemberController extends BaseMultiController{@Resource(name="memberService")private MemberService memberService;public void setMemberService(MemberService memberService) {this.memberService = memberService;}@RequestMapping(value={"/add","/add.html"},method={RequestMethod.GET})public ModelAndView add(HttpServletRequest request,HttpServletResponse response){Map<String,Object> map = new HashMap<String, Object>();return toView("member/add", map);}@RequestMapping(value={"/add","/add.html"},method={RequestMethod.POST})public ModelAndView addMember(HttpServletRequest request,HttpServletResponse response,@ModelAttribute("member")Member member){Map<String,Object> map = new HashMap<String, Object>();System.out.println(member);map.put("message", "成功添加數據到庫," + member);this.memberService.add(member);return toView("member/message", map);}@RequestMapping(value={"/{id:\\d+}/query","/{id:\\d+}/query.html"},method={RequestMethod.GET,RequestMethod.POST})public ModelAndView queryMember(HttpServletRequest request,HttpServletResponse response,@PathVariable("id")String id){Map<String,Object> map = new HashMap<String, Object>();System.out.println(id);Member member = this.memberService.get(id);if(null!=member){map.put("message", "查詢Id=" + id + "的用戶名為:" + member.getNickname());}else{map.put("message", "沒有查詢到與Id=" + id + "相關的數據");}return toView("member/message", map);}@RequestMapping(value={"/{id:\\d+}/delete","/{id:\\d+}/delete.html"},method={RequestMethod.GET,RequestMethod.POST})public ModelAndView deleteMember(HttpServletRequest request, HttpServletResponse response,@PathVariable("id")String id){Map<String,Object> map = new HashMap<String, Object>();try {this.memberService.delete(id);map.put("message", "刪除Id為" + id +"的用戶成功.");} catch (Exception e) {e.printStackTrace();map.put("message", "刪除Id為" + id +"的用戶失敗, "+e.getMessage());}return toView("member/message", map); }}
