Spring注解版配置

　　整了一下午，测通注解版的Spring 3.0配置，备忘一下。

<?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:context="http://www.springframework.org/schema/context"
    xmlns:p="http://www.springframework.org/schema/p"
    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/>      

    <context:component-scan base-package="test,abc"/>

</beans>

　　其中context:annotation-config自动加载4种注入处理器：AutowiredAnnotationBeanPostProcessor, CommonAnnotationBeanPostProcessor, PersistenceAnnotationBeanPostProcessor 和 RequiredAnnotationBeanPostProcessor。context:component-scan的base-package属性定义Spring自动实例化Bean的包（多个包用逗号隔开），其处理的注解有：@Component, @Service, @Repository, @Controller。
