spring aop攔截controller和service

spring配置:

<context:component-scan base-package="me.zxw135136" >
    <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan>

<aop:aspectj-autoproxy />
           

spring-mvc配置:

<context:component-scan base-package="me.zxw135136" use-default-filters="false">
    <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan>

<aop:aspectj-autoproxy />
           

切面類:

@Component
@Aspect
public class LogAspect {

    @Pointcut("execution(* me.zxw135136.novelWeb.service..*(..))")
    private void servicePointCut() {}

    @Pointcut("execution(* me.zxw135136.novelWeb.controller..*(..))")
    private void controllerPointCut() {}

    @Around("servicePointCut()")
    public Object logAroundService(ProceedingJoinPoint jointPoint) throws Throwable {

        System.out.println(jointPoint+"開始");

        Object proceed = jointPoint.proceed();

        System.out.println(jointPoint+"結束");

        return proceed;
    }

    @Around("controllerPointCut()")
    public Object logAroundController(ProceedingJoinPoint jointPoint) throws Throwable {

        System.out.println(jointPoint+"開始");

        Object proceed = jointPoint.proceed();

        System.out.println(jointPoint+"結束");

        return proceed;
    }

}
           

需要注意的是:

1.controller需要使用cglib動态代理才可以攔截,高版本spring可以自動選擇jdk或者cglib代理,在低版本中

aop:aspectj-autoproxy

必須加上

proxy-target-class="true"

才能指定使用cglib代理。

2.aop切面類必須與目标類在同一個上下文環境。因為切面類要同時切入controller和service,而我的spring上下文環境不包含controller,spring-mvc上下文環境不包含service,是以需要在spring和spring-mvc配置檔案中都配置

<aop:aspectj-autoproxy />
