Spring3.2+mybatis3.2+Struts2.3整合

1.Spring3.2不能用于JDK1.8，只能用于JDK1.7。JDK1.8用spring4.0.

2.导入的jar包

3.目录结构:

4.配置Spring

配置数据库信息:

95         <aop:advisor advice-ref="firstTx" pointcut-ref="texPc"/>
96     </aop:config>
97 </beans>

配置service

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.2.xsd ">

    <!--4.注解扫描service  -->
    <!-- 4.开启组件自动扫描，也就是启用注解。前提是导入spring-context-3.2.xsd约束和引入新的命名空间，注解扫描service出错了 -->

        <context:component-scan base-package="cn.xm.service"></context:component-scan> 

    <!-- userService配置 -->
<!--     <bean name="userService" class="cn.xm.service.impl.UserServiceImpl"></bean> -->

</beans>

配置Action

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.2.xsd ">
    <!-- 与struts2整合的配置 -->

    <!-- Action配置 -->
    <bean name="userAction" class="cn.xm.web.action.UserAction" scope="prototype">
        <property name="userService" ref="userService"></property>
    </bean>

</beans>

4.配置Struts

<?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">

<struts>
     <!--
     package的名字必须唯一！只能拦截.action请求
        默认值:class:com.opensymphony.xwork2.ActionSupport
         method:execute
         result的name属性:success   方法中返回success即可跳转到结果对应的页面

 -->
      <!--
    ### if specified, the default object factory can be overridden here
### Note: short-hand notation is supported in some cases, such as "spring"
###       Alternatively, you can provide a com.opensymphony.xwork2.ObjectFactory subclass name here
# struts.objectFactory = spring

### specifies the autoWiring logic when using the SpringObjectFactory.
### valid values are: name, type, auto, and constructor (name is the default)
struts.objectFactory.spring.autoWire = name
   -->

    <constant name="struts.custom.i18n.resources" value="errors"></constant>
    <!--
    struts.objectFactory = spring    :将Struts创建对象工厂改为Spring
    struts.objectFactory.spring.autoWire = name    spring自动装配Struts的依赖属性(默认开启)
      -->
    <constant name="struts.objectFactory" value="spring"></constant>

    <!-- 第一个package命名空间 -->
    <package name="user" namespace="/" extends="struts-default">

      <action name="user_*" class="userAction" method="{1}">
          <result>/index.jsp</result>
      </action>

    </package>

</struts>

5.配置mybatis

<?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>

    <!--  只需要定义个别名,这个应该有-->
     <typeAliases >
         <package name="cn.xm.pojo"/>
     </typeAliases>
    <!-- 动态代理也不需要配置这个扫描，留着也行 -->
    <mappers>
        <!-- 原始DAO开发使用这个手动加载xml -->
        <package name="cn.xm.mapper"/>
    </mappers>

</configuration>

6.总结:

要想使用sring扫描需要在配置文件中开启自动扫描service

　　　　<context:component-scan base-package="cn.xm.service"></context:component-scan>

要想在Service装配动态代理对象
