springmvc基础篇—拆分配置文件

一般来讲，在企业实际项目中通常会将配置文件设置为两个:spring-mvc.xml、beans.xml，各自管各自的内容，方便管理。

一、在src下增加如下配置文件：

<?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:mvc="http://www.springframework.org/schema/mvc"
    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/mvc 
                        http://www.springframework.org/schema/mvc/spring-mvc-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 ">
    
    <!-- 自动扫描 -->
    <context:component-scan base-package="cn.cfs.springmvc.service,cn.cfs.springmvc.dao"/>

</beans>

二、配置web.xml

    <!-- 将beans配置文件load到spring-mvc配置文件中 -->
     <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:beans.xml</param-value>
    </context-param>
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener> 

三、spring-mvc.xml中自动包扫描只保留controller的包扫描。
