Spring学习笔记--自动检测

要使用自动检测，我们需要用到<context:annotation-scan>标签。<context:annotation-scan>元素除了完成与<context:annotation-config>一样的工作，还允许Spring自动检测Bean和定义Bean。此时我们只需要很少量的代码来完成配置：

<?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"
    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-scan
      base-package="com.moonlit.myspring" />

  <bean id="guanyu" class="com.moonlit.myspring.GuanYu" />

</beans>
