Web项目Spring基本配置

1、如果项目全程使用Spring注解来完成依赖注入，则需要在Spring基本配置文件中声明注解解释器，配置注解扫描包路径

<?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"  
    ...
        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  
    ...
        <context:annotation-config/>
       
        <!-- 使用该配置上条配置可省略 -->
        <context:component-scan base-package="com.meng"/>
    </beans>
