</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

<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.web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">

</filter-mapping>
</web-app>
7.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
