不多说，就是配置文件头引入不到位
启用注解时
applicationContext.xml文件头部需要加入
xmlns:context="http://www.springframework.org/schema/context"
但是接着会报错误
BeanFactory not initialized or already closed - call 'refresh' before access
原因是还要在bean头文件中加入http://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context-2.5.xsd
bean头文件配置
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation=" http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/txhttp://www.springframework.org/schema/tx/spring-tx-3.0.xsd http://www.springframework.org/schema/aophttp://www.springframework.org/schema/aop/spring-aop-3.0.xsdx http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"> <context:annotation-config/>
