SpringBoot webmvc项目导出war包并在外部tomcat运行产生的诸多问题以及解决方案

發(fā)布時(shí)間：2025/3/21 javascript 27 豆豆

生活随笔收集整理的這篇文章主要介紹了 SpringBoot webmvc项目导出war包并在外部tomcat运行产生的诸多问题以及解决方案小編覺得挺不錯(cuò)的,現(xiàn)在分享給大家,幫大家做個(gè)參考.

背景:

　　有需求要將原來的Spring(3.2.6) + Springmvc + Hibernate項(xiàng)目重構(gòu)為Springboot(1.5.2)項(xiàng)目

描述:

　　記錄重構(gòu)過程,以及期間遇到的種種問題和對(duì)應(yīng)的解決方案　　

環(huán)境:

　　原項(xiàng)目: win10 + eclipse + jdk1.8 + mysql5.7

　　新項(xiàng)目: win10 + IDEA + jdk1.8?+ mysql5.7 + Maven

過程:

　　第一步: ?新建Maven項(xiàng)目

　　　　IDEA: project > New > Module > Maven (選擇 maven-archetype-quickstart 快速創(chuàng)建一個(gè)maven項(xiàng)目, 如下圖)

　　　　點(diǎn)擊Next, 自己想一個(gè)項(xiàng)目的 groupid(一般為項(xiàng)目域名的倒寫) 和 artifactid(項(xiàng)目名) 并填好(如下圖)

　　　　點(diǎn)擊Next, 確認(rèn)創(chuàng)建信息

　　　　點(diǎn)擊Next, 選擇項(xiàng)目創(chuàng)建文件夾地址

　　　　點(diǎn)擊確認(rèn)自動(dòng)創(chuàng)建項(xiàng)目

　　　　項(xiàng)目創(chuàng)建就完成了

　　　　如果發(fā)現(xiàn)創(chuàng)建maven項(xiàng)目十分緩慢, 很可能是由于訪問maven官方中央倉庫網(wǎng)速太差導(dǎo)致的,建議可以修改Maven的settings.xml文件

　　　　將默認(rèn)的倉庫地址改為國內(nèi)阿里云的地址(http://maven.aliyun.com/nexus/content/groups/public/),(如下圖)

　　　第二步: 配置pom.xml

　　　　　不多說,上代碼,如果對(duì)其中某些節(jié)點(diǎn)含義不清楚, 可以參考此博文:?https://www.cnblogs.com/hafiz/p/5360195.html

　　　第三步: 創(chuàng)建配置文件, 特別注意: ?log4j2.xml 只能放在resources目錄下, 否則導(dǎo)出的war包,配置的log4j2將不起作用!!!!

spring:profiles:active: dev # 激活的配置文件include: freemarker,mysql,redis,interceptor # 加載其他配置文件mvc:favicon:enabled: truedebug: true # 是否啟用debugserver:servlet-path: /common # 所有接口請(qǐng)求都交由自定義的Servlet處理了, 所以默認(rèn)的servlet只用于處理靜態(tài)資源 application.yml spring:freemarker:enabled: true # 是否啟用freemarkercache: false # 是否啟用緩存prefix: # 模板文件前綴suffix: .ftl # 模板文件后綴charset: UTF-8 # 模板文件編碼template-loader-path: classpath:templates/ # 模板文件目錄check-template-location: true # 是否檢查模板目錄是否存在content-type: text/html # 模板類型request-context-attribute: req # RequestContext 引用settings: # 更多配置number_format: '0.##' #數(shù)字格式化, 保留兩位小數(shù)allow-request-override: false # 是否允許 request 屬性覆蓋 controller 屬性allow-session-override: false # 是否允許 session 屬性覆蓋 controller 屬性expose-request-attributes: false # 設(shè)置在與模板合并之前，是否應(yīng)該將所有HttpRequest屬性添加到模型中。expose-session-attributes: false # 設(shè)置在與模板合并之前，是否應(yīng)該將所有HttpSession屬性添加到模型中。expose-spring-macro-helpers: true # 設(shè)置是否公開一個(gè)請(qǐng)求上下文，以供Spring的宏庫使用，名稱為“springMacroRequestContext”prefer-file-system-access: true # 更喜歡文件系統(tǒng)訪問模板加載。文件系統(tǒng)訪問支持對(duì)模板更改進(jìn)行熱檢測(cè)。 # view-names: # whitelist of view names that can be resolved application-freemarker.yml front:login:excludeUrls: # 這里配置的前臺(tái)登入驗(yàn)證的白名單- /hello.sv- /hello2.sv- /index.jtk- /autho.jtk- /code.jtk- /checkLogin.jtk- /checkUser.jtk- /test.jtk- /wxPay/notify.jtk- /api/list.jtk- /api/deposit.jtk- /config/wechat.jtkback:login:excludeUrls: # 這里配置的后臺(tái)登入驗(yàn)證的白名單- /login.do- /logout.do- /game/scores.do- /game/dayScore.do application-interceptor.yml spring:datasource:# 數(shù)據(jù)庫訪問配置# 主數(shù)據(jù)源，默認(rèn)的type: com.alibaba.druid.pool.DruidDataSourcedbUrl: jdbc:mysql://localhost:3306/hotpot?useUnicode=true&characterEncoding=utf-8&useSSL=falseusername: yjypassword: yyyyyydriverClassName: com.mysql.jdbc.Driver# 下面為連接池的補(bǔ)充設(shè)置，應(yīng)用到上面所有數(shù)據(jù)源中# 初始化大小，最小，最大initialSize: 5minIdle: 5maxActive: 20maxWait: 60000 # 配置獲取連接等待超時(shí)的時(shí)間timeBetweenEvictionRunsMillis: 60000 # 配置間隔多久才進(jìn)行一次檢測(cè)，檢測(cè)需要關(guān)閉的空閑連接，單位是毫秒minEvictableIdleTimeMillis: 300000 # 配置一個(gè)連接在池中最小生存的時(shí)間，單位是毫秒validationQuery: SELECT 1 FROM DUALtestWhileIdle: truetestOnBorrow: falsetestOnReturn: falsepoolPreparedStatements: true # 打開PSCache，并且指定每個(gè)連接上PSCache的大小maxPoolPreparedStatementPerConnectionSize: 20filters: stat,wall,log4j # 配置監(jiān)控統(tǒng)計(jì)攔截的filters，去掉后監(jiān)控界面sql無法統(tǒng)計(jì)，'wall'用于防火墻connectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=5000 # 通過connectProperties屬性來打開mergeSql功能；慢SQL記錄useGlobalDataSourceStat: true # 合并多個(gè)DruidDataSource的監(jiān)控?cái)?shù)據(jù)#JPA Configuration:jpa:database: MYSQLshow-sql: true # Show or not log for each sql querygenerate-ddl: true # Hibernate ddl auto (create, create-drop, update)hibernate:ddl-auto: updatenaming:strategy: org.hibernate.cfg.ImprovedNamingStrategyproperties:hibernate:dialect: org.hibernate.dialect.MySQL5Dialect application-mysql.yml <?xml version="1.0" encoding="UTF-8"?>    <configuration status="INFO" monitorInterval="30"><appenders><console name="Console" target="SYSTEM_OUT"><PatternLayout pattern="[%d{HH:mm:ss:SSS}] [%p] -

　　第四步: 主類(一般放在根包中)

package com.yjy.test;import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.EnableAutoConfiguration; import org.springframework.boot.autoconfigure.domain.EntityScan; import org.springframework.boot.builder.SpringApplicationBuilder; import org.springframework.boot.web.servlet.ServletComponentScan; import org.springframework.boot.web.support.SpringBootServletInitializer; import org.springframework.context.annotation.ComponentScan; import org.springframework.context.annotation.Configuration; import org.springframework.context.annotation.PropertySource;/*** SpringBoot 啟動(dòng)入口** @Author yjy* @Date 2018-04-17 12:43*/ //@SpringBootApplication = (@Configuration, @EnableAutoConfiguration, @ComponentScan) @Configuration @EnableAutoConfiguration @ComponentScan @EntityScan("com.yjy.test.game.entity") // 掃描實(shí)體類 @ServletComponentScan(basePackages = "com.yjy.test") // 掃描自定義Servlet @PropertySource(value = { // 導(dǎo)入配置"classpath:/config/application.yml", }) public class Application extends SpringBootServletInitializer {// IDEA運(yùn)行時(shí) 運(yùn)行此函數(shù)public static void main(String[] args) {SpringApplication.run(Application.class, args);}// 導(dǎo)出war在外部tomcat使用時(shí), 不能使用main函數(shù)運(yùn)行, 需要配置此項(xiàng) @Overrideprotected SpringApplicationBuilder configure(SpringApplicationBuilder application) {return application.sources(Application.class);}}

　　　　第五步: 添加配置類(按自己的需要添加, 無特別說明的情況下, 配置類可以存在任意包內(nèi), 只需滿足包級(jí)別不高于Application.java所在的包就可以

　　　　　　當(dāng)然也可以通過配置掃描包注解來自定義, 默認(rèn)掃描主類所在包以下的所有包)

　　　　　　1: 全局跨域配置類(放在與Application.java同目錄下)

package com.yjy.test;import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.web.cors.CorsConfiguration; import org.springframework.web.cors.UrlBasedCorsConfigurationSource; import org.springframework.web.filter.CorsFilter;/*** 跨域配置** @Author yjy* @Date 2018-04-26 15:55*/ @Configuration public class CorsConfig {private CorsConfiguration buildConfig() {CorsConfiguration corsConfiguration = new CorsConfiguration();corsConfiguration.addAllowedHeader("*");corsConfiguration.addAllowedMethod("*");corsConfiguration.addAllowedOrigin("*");corsConfiguration.setAllowCredentials(true);return corsConfiguration;}@Beanpublic CorsFilter corsFilter() {UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();source.registerCorsConfiguration("/**", buildConfig());return new CorsFilter(source);}} 跨域配置

　　　　　　2: Date參數(shù)的格式化( 請(qǐng)求中符合格式的字符串參數(shù)可以使用Date類型接收參數(shù), 比如請(qǐng)求參數(shù) ?addTime=20180101, Controller層可以使用 func(Date addTime); 接收, 否則會(huì)報(bào)400錯(cuò)誤)

package com.yjy.test;import org.apache.commons.lang3.StringUtils; import org.springframework.core.convert.converter.Converter; import org.springframework.stereotype.Component;import java.text.ParseException; import java.text.SimpleDateFormat;/*** Date參數(shù)格式化** 嘗試格式化java.util.Date類型的參數(shù)** @Author yjy* @Date 2018-04-27 9:58*/ @Component public class DateConverterConfig implements Converter<String, java.util.Date> {private static final String[] formats = new String[] {"yyyy-MM-dd", // 0"yyyy-MM", // 1"yyyy-MM-dd HH:mm:ss", // 2"yyyy-MM-dd HH:mm", // 3 };/*** 這里將參數(shù)格式化成 java.sql.Date 為了方便后面用來拼接sql* @param param 日期格式的字符串* @return java.sql.Date*/@Overridepublic java.sql.Date convert(String param) {if (StringUtils.isBlank(param)) {return null;}param = param.trim();if (param.matches("^\\d{4}-\\d{1,2}-\\d{1,2}$")) {return parseDate(param, formats[0]);}if (param.matches("^\\d{4}-\\d{1,2}$")) {return parseDate(param, formats[1]);}if (param.matches("^\\d{4}-\\d{1,2}-\\d{1,2} \\d{1,2}:\\d{1,2}:\\d{1,2}$")) {return parseDate(param, formats[2]);}if (param.matches("^\\d{4}-\\d{1,2}-\\d{1,2} \\d{1,2}:\\d{1,2}$")) {return parseDate(param, formats[3]);}throw new IllegalArgumentException("Invalid date param '" + param + "'");}/*** 格式化日期* @param dateStr 日期字符串* @param format 格式* @return 日期*/private java.sql.Date parseDate(String dateStr, String format) {java.sql.Date date = null;try {SimpleDateFormat simpleDateFormat = new SimpleDateFormat(format);java.util.Date dates = simpleDateFormat.parse(dateStr);date = new java.sql.Date(dates.getTime());} catch (ParseException e) {e.printStackTrace();}return date;}} 日期參數(shù)格式化配置

　　　　　　3: 自定義指定請(qǐng)求前綴的Servlet(一個(gè)前臺(tái), 一個(gè)后臺(tái))

package com.yjy.test.game.web.servlet;import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.web.servlet.DispatcherServlet; import javax.servlet.annotation.WebServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse;/*** 后臺(tái)servlet* 需要添加對(duì)應(yīng)的 *-servlet.xml** @Author yjy* @Date 2018-04-23 16:26*/ @WebServlet(name = "backServlet", urlPatterns = {"/manager/admin/*"}) public class CustomBackServlet extends DispatcherServlet {private static final Logger log = LoggerFactory.getLogger(CustomBackServlet.class);@Overrideprotected void doService(HttpServletRequest request, HttpServletResponse response) throws Exception {log.info("backServlet doService...");super.doService(request, response);}} 后臺(tái)自定義Servlet package com.yjy.test.game.web.servlet;import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.web.servlet.DispatcherServlet; import javax.servlet.annotation.WebServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse;/*** 前臺(tái)servlet* 需要添加對(duì)應(yīng)的 *-servlet.xml** @Author yjy* @Date 2018-04-23 16:26*/ @WebServlet(name = "frontServlet", urlPatterns = {"/*"}) public class CustomFrontServlet extends DispatcherServlet {private static final Logger log = LoggerFactory.getLogger(CustomFrontServlet.class);@Overrideprotected void doService(HttpServletRequest request, HttpServletResponse response) throws Exception {log.info("frontServlet doService...");super.doService(request, response);}} 前臺(tái)自定義Servlet

　　　　　　對(duì)應(yīng)的默認(rèn)xml文件, 打包war的時(shí)候需要, 看pom.xml中相應(yīng)配置, 否則到外部tomcat運(yùn)行時(shí), 會(huì)報(bào)找不到對(duì)應(yīng)的配置文件的錯(cuò)誤

　　　　　　xml內(nèi)容都是一樣的

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd"></beans> 自定義Servlet默認(rèn)配置

?　　　　　　4: 因?yàn)樯厦鎯蓚€(gè)自定義的Servlet繼承自DispatcherServlet, 不允許重寫init()方法, 所以如果需要自定義初始化ServletContext, 則必須自己寫一個(gè)Servlet繼承HttpServlet,(?此Servlet不需要配置相應(yīng)的xml文件)

package com.yjy.test.game.web.servlet;import com.yjy.test.game.service.OptionItemService; import org.springframework.web.context.WebApplicationContext; import org.springframework.web.context.support.WebApplicationContextUtils;import javax.servlet.ServletException; import javax.servlet.annotation.WebServlet; import javax.servlet.http.HttpServlet;/*** 自定義初始化 ServletContext** WebServlet中 urlPatterns必須填寫, 否則不會(huì)加載此Servlet, 同時(shí)需要配置 loadOnStartup = 1** @Author yjy* @Date 2018-05-02 11:47*/ @WebServlet(urlPatterns = "", loadOnStartup = 1) public class DictServlet extends HttpServlet {private OptionItemService optionItemService;public void setOptionItemService(OptionItemService optionItemService) {this.optionItemService = optionItemService;}public void init() throws ServletException {System.out.println("DictServlet init..............................");WebApplicationContext wac = WebApplicationContextUtils.getRequiredWebApplicationContext(this.getServletContext());setOptionItemService(wac.getBean (OptionItemService.class));optionItemService.getAllFieldName();// init something...// 例子: 設(shè)置Servlet全局屬性this.getServletContext().setAttribute("appName", "項(xiàng)目名");super.init();}} 初始化ServletContext

　　　　　　5:?靜態(tài)資源請(qǐng)求配置

package com.yjy.test.config;import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.context.annotation.Configuration; import org.springframework.web.servlet.config.annotation.InterceptorRegistry; import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry; import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;/*** 自定義WebMvcConfigurerAdapter配置** @Author yjy* @Date 2018-04-23 11:40*/ @Configuration public class WebMvcConfig extends WebMvcConfigurerAdapter {private static final Logger log = LoggerFactory.getLogger(WebMvcConfig.class);/*** 靜態(tài)資源請(qǐng)求配置* @param registry 資源處理注冊(cè)器*/@Overridepublic void addResourceHandlers(ResourceHandlerRegistry registry) {log.info("addResourceHandlers...........................");registry.addResourceHandler("/**").addResourceLocations("classpath:/common/");super.addResourceHandlers(registry);}} 靜態(tài)資源配置

　　　　　　6: tomcat上傳配置

package com.yjy.test.config;import org.springframework.boot.web.servlet.MultipartConfigFactory; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import javax.servlet.MultipartConfigElement;/*** 配置tomcat上傳限制** @Author yjy* @Date 2018-04-24 14:38*/ @Configuration public class MultipartConfig {/*** 配置tomcat上傳限制* @return 配置*/@Beanpublic MultipartConfigElement multipartConfigElement(){MultipartConfigFactory factory = new MultipartConfigFactory();factory.setMaxFileSize("50MB");factory.setMaxRequestSize("10MB");return factory.createMultipartConfig();}} 上傳配置

　　　　第六步: 遷移原項(xiàng)目源碼幾個(gè)遇到問題的點(diǎn):

　　　　2: 重寫B(tài)ase層(代碼如下),注意: 原來BaseDaoImpl中的 sessionFactory 沒有了, 就是說不能通過getSession().createSQLQuery(sql) 的方式獲取SQLQuery了, 需要通過em.createNativeQuery(sql).unwrap(SQLQuery.class); 來獲得SQLQuery, em在BaseServiceImpl中已經(jīng)注入, 通過這種方式可以兼容之前的代碼

package com.yjy.test.game.redis;import org.springframework.beans.factory.annotation.Value; import org.springframework.boot.context.properties.ConfigurationProperties; import org.springframework.context.annotation.PropertySource; import org.springframework.stereotype.Component; import org.springframework.validation.annotation.Validated;import javax.validation.constraints.NotNull;@Component @Validated public class RedisConfig {@NotNullpublic static String addr; //Redis服務(wù)器IP @NotNullpublic static int port; //Redis的端口號(hào)public static String auth; //訪問密碼 @NotNullpublic static int maxActive = 10; // 可用連接實(shí)例的最大數(shù)目，默認(rèn)值為8；如果賦值為-1，則表示不限制；// 如果pool已經(jīng)分配了maxActive個(gè)jedis實(shí)例，則此時(shí)pool的狀態(tài)為exhausted(耗盡)。 @NotNullpublic static int maxIdle = 200; //控制一個(gè)pool最多有多少個(gè)狀態(tài)為idle(空閑的)的jedis實(shí)例，默認(rèn)值也是8。 @NotNullpublic static int timeOut = 2000; //連接的超時(shí)時(shí)間 @NotNullpublic static int maxWait = 10000; //等待可用連接的最大時(shí)間，單位毫秒，默認(rèn)值為-1，表示永不超時(shí)。如果超過等待時(shí)間，則直接拋出JedisConnectionException； @NotNullpublic static boolean testOnBorrow = true; //在borrow一個(gè)jedis實(shí)例時(shí)，是否提前進(jìn)行validate操作；如果為true，則得到的jedis實(shí)例均是可用的； @NotNullpublic static boolean testOnReturn = true; //在return一個(gè)jedis實(shí)例時(shí)，是否提前進(jìn)行validate操作. @Value("${redis.addr}")public void setAddr(String addr) {this.addr = addr;}@Value("${redis.port}")public void setPort(int port) {this.port = port;}@Value("${redis.auth}")public void setAuth(String auth) {this.auth = auth;}@Value("${redis.maxActive}")public void setMaxActive(int maxActive) {this.maxActive = maxActive;}@Value("${redis.maxIdle}")public void setMaxIdle(int maxIdle) {this.maxIdle = maxIdle;}@Value("${redis.timeOut}")public void setTimeOut(int timeOut) {this.timeOut = timeOut;}@Value("${redis.maxWait}")public void setMaxWait(int maxWait) {this.maxWait = maxWait;}@Value("${redis.testOnBorrow}")public void setTestOnBorrow(boolean testOnBorrow) {this.testOnBorrow = testOnBorrow;}@Value("${redis.testOnReturn}")public void setTestOnReturn(boolean testOnReturn) {this.testOnReturn = testOnReturn;}public static void printAllConfig() {System.out.println("RedisConfig{" +"addr='" + addr + '\'' +", port=" + port +", auth='" + auth + '\'' +", maxActive=" + maxActive +", maxIdle=" + maxIdle +", timeOut=" + timeOut +", maxWait=" + maxWait +", testOnBorrow=" + testOnBorrow +", testOnReturn=" + testOnReturn +'}');}} RedisConfig.java

大概就是這么個(gè)樣子!!! 嗯
