Maven+Struts2+MyBatis+Spring搭建教程
教程目标：
在MyEclipse中搭建Struts2+MyBatis+Spring环境，用Maven管理项目，利用mybatis-gernerator插件生成部分代码
附带目标：
struts2的自定义拦截器和国际化，mybatis-spring自动装配Dao，mybatis-gernerator的配置
?
先贴下搭建成功后项目的结构图，方便理解：
?
1、新建web project，add maven spport：
2、编辑已经生成的pom.xml：pom文件不是一口气写完的，而是随着添加struts、mybatis和spring等特性以后才逐渐完成的，我在这里就把完成以后的贴在这里了

3、编辑web.xml：
?
?
?
<?xml version="1.0" encoding="UTF-8"?><web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"> <display-name>MybatisSpringStrut2</display-name> <!-- struts2过滤器配置 --><filter><filter-name>struts2</filter-name><filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class></filter><filter-mapping><filter-name>struts2</filter-name><url-pattern>/*</url-pattern></filter-mapping><!-- 集成spring --><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><!-- spring的配置文件位置 --><context-param><param-name>contextConfigLocation</param-name><param-value>classpath*:spring/applicationContext*.xml</param-value></context-param><!-- 欢迎页面配置 --><welcome-file-list><welcome-file>site/index.jsp</welcome-file></welcome-file-list></web-app>?
?
4、struts2的配置文件：
?
strutsxml:
?
?
<?xml version="1.0" encoding="UTF-8"?><web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"> <display-name>MybatisSpringStrut2</display-name> <!-- struts2过滤器配置 --><filter><filter-name>struts2</filter-name><filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class></filter><filter-mapping><filter-name>struts2</filter-name><url-pattern>/*</url-pattern></filter-mapping><!-- 集成spring --><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><!-- spring的配置文件位置 --><context-param><param-name>contextConfigLocation</param-name><param-value>classpath*:spring/applicationContext*.xml</param-value></context-param><!-- 欢迎页面配置 --><welcome-file-list><welcome-file>site/index.jsp</welcome-file></welcome-file-list></web-app>
?
?
struts/struts-admin.xml:
?
?
<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" "http://struts.apache.org/dtds/struts-2.0.dtd"><struts><!-- result type：<result-types> <result-type name="chain" default="true"/> <result-type name="freemarker" /> </result-types> --><package name="admin" namespace="/admin" extends="my-truts2"><action name="login"><result>/admin/login.jsp</result></action><action name="main"><result>/admin/main.jsp</result></action><!-- 测试拦截器 --><action name="testInterceptor" method="testInterceptor"><interceptor-ref name="adminLoginInterceptorStack"/><result>/admin/main.jsp</result></action><!-- 测试数据访问功能CRUD --><action name="testCrud" method="testCrud"><result>/admin/main.jsp</result></action></package></struts>
?
?
struts/struts-index.xml:
?
?
<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" "http://struts.apache.org/dtds/struts-2.0.dtd"><struts><!-- result type：<result-types> <result-type name="chain" default="true"/> <result-type name="freemarker" /> </result-types> --><package name="index" namespace="/" extends="my-truts2"><action name="index"><result>/site/index.jsp</result></action><action name="language"><result type="redirectAction">index</result></action></package></struts>?
?
?
5、spring的配置文件，位于src/config/spring:
?
applicationContext.xml:
?
?
?
<?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: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.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"><!-- 数据源连接信息配置文件 --><context:property-placeholder location="classpath*:jdbc.properties" /><!-- 开发环境数据源 --><bean id="dataSource_dev" value="${jdbc.driverClassName.mysql_dev}" /><property name="url" value="${jdbc.url.mysql_dev}" /><property name="username" value="${jdbc.username.mysql_dev}" /><property name="password" value="${jdbc.password.mysql_dev}" /></bean><!-- 生产环境数据源 --><bean id="dataSource_product" value="${jdbc.driverClassName.mysql}" /><property name="jdbcUrl" value="${jdbc.url.mysql}" /><property name="user" value="${jdbc.username.mysql}" /><property name="password" value="${jdbc.password.mysql}" /><property name="maxPoolSize" value="${c3p0.maxPoolSize}" /><property name="acquireIncrement" value="${c3p0.acquireIncrement}" /><property name="minPoolSize" value="${c3p0.minPoolSize}" /><property name="maxIdleTime" value="${c3p0.maxIdleTime}" /></bean><!-- 配置sqlSessionFactory --><bean id="sqlSessionFactory" ref="dataSource_dev" /><!-- 自动到mappers包下面去搜索mybatis的映射文件 --><property name="mapperLocations" value="classpath*:mappers/**/*.xml" /></bean><!-- 使用Spring的事务管理器 --><bean id="transactionManager"ref="dataSource_dev" /></bean></beans>?applicationContextDao.xml:
?
?
<?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: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.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"><!-- 单个的注册 MapperFactoryBean --><!-- <bean id="managerVOMapper" value="com.xylcolor.dao.ManagerVOMapper" /><property name="sqlSessionFactory" ref="sqlSessionFactory" /></bean>--><!-- 利用MyBatis-Spring的自动装配机制：自动从com.xylcolor.dao包中寻找接口装配成MapperFactoryBean 有了下面这个配置，那么就不需要像上面那样一个一个的去注册映射器Bean了，大大的减少了工作量--><bean value="com.xylcolor.dao" /></bean></beans>?
applicationContextService.xml:
?
?
?
<?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: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.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"> <bean id="newsService" --><property name="newsVOMapper" ref="newsVOMapper" /></bean></beans>
?
?
applicationContextActions.xml:
?
?
<?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: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.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"><bean id="adminAction" ref="newsService"/></bean></beans>
?
?
6、mybatis的配置文件：mybatis-config.xml，这个文件在我们现在这个环境中其实可以不用，除非你一定要定义一些
typeAliases或者settings；项目中实际要用到的映射文件会由插件生成，由mybatis-spring根据你给的路径自动寻找装配：
?
?
mybatis-config.xml：
?
?
?
<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN""http://mybatis.org/dtd/mybatis-3-config.dtd"><configuration><settings><setting name="cacheEnabled" value="true"/><setting name="lazyLoadingEnabled" value="true"/><setting name="aggressiveLazyLoading" value="true"/></settings><!-- 别名配置 --><typeAliases><typeAlias alias="NewsVO" type="com.xylcolor.vo.model.NewsVO"/></typeAliases></configuration>
?
?
7、代码生成插件的配置文件：mybatis-generator.xml
?
?
<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE generatorConfiguration PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN" "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd"><!-- mybatis-generator插件生成代码的配置文件 --><generatorConfiguration><classPathEntry location="${classPathEntry.location}" /><context id="MySQLTables" targetRuntime="MyBatis3"><jdbcConnection drivervalue="false" /></javaTypeResolver><!-- 生成 Model，POJO --><javaModelGenerator targetPackage="com.xylcolor.vo.model" targetProject="${model.target.dir}"><property name="enableSubPackages" value="true" /><property name="trimStrings" value="true" /></javaModelGenerator><!-- 生成映射文件*.xml --><sqlMapGenerator targetPackage="mappers" targetProject="${mappers.target.dir}"><property name="enableSubPackages" value="true" /></sqlMapGenerator><!-- 生成映射器类 --><javaClientGenerator type="XMLMAPPER" targetPackage="com.xylcolor.dao" targetProject="${client.target.dir}"><property name="enableSubPackages" value="true" /></javaClientGenerator><!-- 指定要生成的表名和对应形成的POJO类名 --><table schema="" tableName="tb_news" domainObjectName="NewsVO"/></context></generatorConfiguration>?
完成上面那些配置文件以后，基本上配置上就完成了，下面的工作就是java代码的完成了，具体的示例代码见附件，必要的地方我都做了注释。
?
看看实际运行情况：
1.国际化：
?
2：利用插件生成的代码，完成数据的增删改查：
?
/** * 测试数据的增删改查 * @return * @throws JSONException */public String testCrud() throws JSONException{String b = "<br />";String response = "测试数据的增删改查:<br />";//查NewsVOExample example = new NewsVOExample();example.or().andIdIsNotNull();List<NewsVO> list = newsService.selectByExample(example);response += "原始数据：<br />";for (NewsVO newsVO : list) {response += JSONUtil.serialize(newsVO)+b;}//增NewsVO record = new NewsVO();record.setTitle("这是我新增的一个新闻");record.setContent("2012其实真的快到了");record.setSource("火星资讯");record.setDate(new Date());int result = newsService.insert(record);response += result==1?"插入新数据成功":"插入数据失败"+b;list = newsService.selectByExample(example);response += "插入数据后："+b;for (NewsVO newsVO : list) {response += JSONUtil.serialize(newsVO)+b;}//改record = newsService.selectByExample(example).get(0);response += "修改前的数据:"+b+JSONUtil.serialize(record);example = new NewsVOExample();example.or().andTitleEqualTo(record.getTitle());int originId = record.getId();record.setTitle("这是我修改后的标题");result = newsService.updateByExample(record, example);response += result==1?"修改成功":"修改失败"+b;example.or().andTitleEqualTo(record.getTitle());record = newsService.selectByPrimaryKey(originId);response +="修改后的数据:"+b+JSONUtil.serialize(record)+b;//删example.or().andTitleEqualTo("这是我新增的一个新闻");newsService.deleteByExample(example);example.or().andIdIsNotNull();list = newsService.selectByExample(example);response += "删除数据后："+b;for (NewsVO newsVO : list) {response += JSONUtil.serialize(newsVO)+b;}write(response);return SUCCESS;}?
你说啥，我没看懂！
