没有调用Spring AOP Pointcut

Question

我使用JSF 2.2 + Spring框架3.2.4

所以,我有这个applicationContent.xml

<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:tx="http://www.springframework.org/schema/tx"
      xmlns:aop="http://www.springframework.org/schema/aop"
      xmlns:p="http://www.springframework.org/schema/p"
      xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
        http://www.springframework.org/schema/aop
        http://www.springframework.org/schema/aop/spring-aop-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/tx 
        http://www.springframework.org/schema/tx/spring-tx.xsd">

    <aop:aspectj-autoproxy proxy-target-class="true" />
    <tx:annotation-driven transaction-manager="transactionManager"/>
    <context:annotation-config/>
    <context:component-scan base-package="com.vulcan.controller" />
    <context:component-scan base-package="com.vulcan.service" />
    <context:component-scan base-package="com.vulcan.dao" />
    <context:component-scan base-package="com.vulcan.spring.aop" />

.....

然后我有方面组件

package com.vulcan.spring.aop;

@Aspect
public class LoggingService {
    private Log log = LogFactory.getLog(this.getClass());

    @Pointcut("execution(* *.*(..))")
    protected void loggingOperation() {}

    @Before("loggingOperation()")
    public void logJoinPoint()
    {
        System.out.println ("Hello");
     }
   ....

通过这种类型的执行,我假设将在每个方法上触发此切入点.但问题是,这个切入点没有被触发？知道为什么吗？谢谢

仅供参考,我使用glassfish 4,当我部署我的网络应用程序时,我没有收到任何错误配置.所以我认为我的配置很好.

Answer 1

@AspectSpring没有自动检测到注释类,因为没有检测到它,所以<aop:aspectj-autoproxy />bean 不知道.所以基本上没有方面.

添加@Component到带@Aspect注释的类中,以便Spring可以检测并使用该方面.

@Compopnent
@Aspect
public class LoggingService { ... }

或者在xml文件中明确声明方面

<bean class="LoggingService" />

无论哪种方式,<aop:aspectj-autoproxy />bean 都会获取方面,并且会运行建议.
