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 name="plainText" class="org.apache.struts2.dispatcher.PlainTextResult" />
        </result-types>
	 -->

	<package name="admin" namespace="/admin" extends="my-truts2">
		
		<action name="login">

		</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">

	<!--

        </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" class="org.apache.commons.dbcp.BasicDataSource"
		destroy-method="close">
		<property name="driverClassName" 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" class="com.mchange.v2.c3p0.ComboPooledDataSource"
		destroy-method="close">
		<property name="driverClass" 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" class="org.mybatis.spring.SqlSessionFactoryBean">
		<property name="dataSource" 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"
		class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
		<property name="dataSource" 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" class="org.mybatis.spring.mapper.MapperFactoryBean">
		<property name="mapperInterface" 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 class="org.mybatis.spring.mapper.MapperScannerConfigurer">
		<property name="basePackage" 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" class="com.xylcolor.service.impl.NewsServiceImpl">
    	<!-- 
    		这里的ref=newsVOMapper,就是mybatis-spring自动装配的,我们在applicationContextDao.xml
    		文件中并没有显示的注册newsVOMapper这个Bean；
    		当然这个名字为什么就是newsVOMapper呢，默认的会根据Dao接口名称按照驼峰命名习惯来生成这个名称，
    		如果你想拥有自己的名称风格，那么你可以在Dao接口上通过注解@Component或@Named来更改名称，
    		例如：
    		@Component(value="newsVODao")
			public interface NewsVOMapper {……}
			或
			@Named(value="newsVODao")
			public interface NewsVOMapper {……}
			
			这样以后，这里ref就应该是ref="newsVODao" 
    	-->
		<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" class="com.xylcolor.actions.AdminAction">
		<property name="newsService" 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：

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 driverClass="${jdbc.driverClass}"
			connectionURL="${jdbc.connectionURL}"
			userId="${jdbc.userId}"
			password="${jdbc.password}">
		</jdbcConnection>

		<!-- java类型处理器，默认的就这么一个处理器可以用，可以自己写，具体的请参考官方文档http://code.google.com/p/mybatis/wiki/Generator -->
		<javaTypeResolver>
			<property name="forceBigDecimals" value="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;
	}
