struts/spring/mybatis的整合
1.struts配置：struts-*.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
"http://struts.apache.org/dtds/struts-2.3.dtd">
<!-- START SNIPPET: xworkSample -->
<struts>
<!-- Some or all of these can be flipped to true for debugging -->
<constant name="struts.i18n.reload" value="false" />
<!-- 设置开发模式，可以在改了配置文件后不需要重启服务器，刷新浏览器即可，在完成开发后要设置为false -->
<constant name="struts.devMode" value="true" />
<constant name="struts.configuration.xml.reload" value="true" />
<!-- 设置国际化全局的资源文件的基名 -->
<constant name="struts.custom.i18n.resources" value="globalMessages" />
<!-- 设置请求的后缀名，可以设置多个，用逗号隔开-->
<constant name="struts.action.extension" value="action,do," />
<!--上传文件的大小限制
<constant name="struts.multipart.maxSize" value="10701096"/> -->
<!--上传文件的临时目录
<constant name="struts.multipart.saveDir" value="d://"/>-->
<!-- 集成spring，action对象让spring容器来创建 org.apache.struts2.spring.StrutsSpringObjectFactory -->
<constant name="struts.objectFactory" value="spring" />
<constant name="" value=""></constant>
<!-- 国际化编码 -->
<constant name="struts.i18n.encoding" value="UTF-8" />
<!-- 浏览器是否缓存静态内容 ，开发阶段最好关闭-->
<constant name="struts.serve.static.browserCache" value="false"/>
<!--
指定spring框架的装配模式，装配方式有: name, type, auto, and constructor (name
是默认装配模式)
-->
<constant name="struts.objectFactory.spring.autoWire" value="name" />
<package name="default" extends="struts-default">
<interceptors>
<interceptor-stack name="crudStack">
<interceptor-ref name="checkbox" />
<interceptor-ref name="params" />
<interceptor-ref name="staticParams" />

</interceptor-stack>
<interceptor-stack name="authStack">

</global-exception-mappings>
</package>
<package name="sys" extends="default" namespace="/sys">
<default-interceptor-ref name="crudStack"/>
<!-- action使用spring的bean -->
<action name="*_*" class="{2}" method="{1}">
<result name="userlist">/WEB-INF/pages/user/list.jsp</result>
<result name="useradd">/WEB-INF/pages/user/add.jsp</result>
<result name="userupdate">/WEB-INF/pages/user/update.jsp</result>
<result name="userlook">/WEB-INF/pages/user/look.jsp</result>
</action>
</package>
</struts>
public class UserAction extends ActionSupport{
private IUserService userService;
private UserVO userVO = new UserVO();
private static final Logger log = Logger.getLogger(UserAction.class);
public String list(){
return "userlist";
}
}
2.web.xml
<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
<init-param>
<param-name>config</param-name>
<param-value>
struts-default.xml,struts-plugin.xml,struts.xml
</param-value>

<param-value>classpath:spring/applicationContext*.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
3.spring 与mybatis的集成配置: applicationContext-*.xml
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
<property name="url" value="jdbc:mysql://localhost:3306/test2"></property>
<property name="driverClassName" value="com.mysql.jdbc.Driver"></property>
<property name="username" value="root"></property>
<property name="password" value="password"></property>
<property name="initialSize" value="2"></property>
<property name="maxActive" value="100"></property>
<property name="maxIdle" value="20"></property>
<property name="minIdle" value="10"></property>
<property name="validationQuery" value="SELECT 1"></property>
</bean>
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource"></property>
<property name="configLocation" value="classpath:configuration.xml"></property>
<property name="mapperLocations" value="classpath:mybatis/**/*.xml"></property>
</bean>
<!-- 普通处理的session -->
<bean id="sqlSessionTemplate" class="org.mybatis.spring.SqlSessionTemplate">
<constructor-arg index="0" ref="sqlSessionFactory" />
<constructor-arg index="1" value="SIMPLE" />
</bean>
<!-- spring的事务管理器 -->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"></property>
</bean>
<!-- 声明式容器事务管理，事务管理器transactionManager -->
<tx:advice id="txAdvice" transaction-manager="transactionManager">
<tx:attributes>
<tx:method name="add*" propagation="REQUIRED"/>
<tx:method name="insert*" propagation="REQUIRED"/>
<tx:method name="update*" propagation="REQUIRED"/>
<tx:method name="query*" read-only="true"/>
<tx:method name="*" propagation="REQUIRED"/>
</tx:attributes>
</tx:advice>
<aop:config expose-proxy="true">
<!-- 只对业务逻辑层实施事务 -->
<aop:pointcut id="txPointcut" expression="execution(* cn.demo.service..*.*(..))" />
<aop:advisor advice-ref="txAdvice" pointcut-ref="txPointcut"/>
</aop:config>
<context:component-scan base-package="cn.demo.action"/>
<bean id="userAction" class="cn.demo.action.UserAction" scope="prototype">
<property name="userService" ref="userService"></property>
</bean>
4.页面访问Action: sys/list_userAction.action
5.mybatis配置：*mapper.xml, configuration.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
<mapper namespace="cn.demo.dao.IUserDao" >
<resultMap id="userMap" type="cn.demo.model.po.UserPO">
<id property="userId" column="USERID" ></id>
<result property="userName" column="USERNAME"></result>
<result property="birthday" column="BIRTHDAY"></result>
<result property="salary" column="SALARY"></result>
<!-- <result property="birthdayStr" column="BIRTHDAY" typeHandler="myDateHandler"></result> -->
</resultMap>
<sql id="userFields">
USERID, USERNAME, BIRTHDAY, SALARY
</sql>
<select id="selectById" parameterType="cn.demo.model.po.UserPO" resultType="cn.demo.model.po.UserPO">
select
<include refid="userFields"></include>
from user
where USERID = #{userId}
</select>
</mapper>
<?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>
<!-- 全局的映射器启用或禁用缓存。 -->
<setting name="cacheEnabled" value="true" />
