java – @AspectJ切入包中的所有方法

我有一个特定的包的这个工作代码,但我想配置它为所有控制器,服务和dao包
例如

> com.abc.xyz.content.controller
> com.abc.xyz.content.service
> com.abc.xyz.content.dao
> com.abc.xyz.category.controller
> com.abc.xyz.category.service
> com.abc.xyz.category.dao

等等. . .
这是我的项目的基础包,有人可以帮助我如何去做,以便它适用于我的网络项目的所有类,包括控制器,谢谢提前.

package com.abc.xyz.utilities;

import java.util.Arrays;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.AfterReturning;
import org.aspectj.lang.annotation.AfterThrowing;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.aspectj.lang.annotation.pointcut;
import org.springframework.core.annotation.Order;
import org.springframework.stereotype.Component;

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

    @pointcut("execution(* com.abc.xyz.content.service..*(..))")
    protected void loggingOperation()
    {
    }

    @Before("loggingOperation()")
    @Order(1)
    public void logJoinPoint(JoinPoint joinPoint)
    {
    log.info("Signature declaring type : " + joinPoint.getSignature().getDeclaringTypeName());
    log.info("Signature name : " + joinPoint.getSignature().getName());
    log.info("Arguments : " + Arrays.toString(joinPoint.getArgs()));
    log.info("Target class : " + joinPoint.getTarget().getClass().getName());
    }

    @AfterReturning(pointcut = "loggingOperation()",returning = "result")
    @Order(2)
    public void logAfter(JoinPoint joinPoint,Object result)
    {
    log.info("Exiting from Method :" + joinPoint.getSignature().getName());
    log.info("Return value :" + result);
    }

    @AfterThrowing(pointcut = "execution(* com.abc.xyz.content.service..*(..))",throwing = "e")
    @Order(3)
    public void logAfterThrowing(JoinPoint joinPoint,Throwable e)
    {
    log.error("An exception has been thrown in " + joinPoint.getSignature().getName() + "()");
    log.error("Cause :" + e.getCause());
    }

    @Around("execution(* com.abc.xyz.content.service..*(..))")
    @Order(4)
    public Object logAround(ProceedingJoinPoint joinPoint) throws Throwable
    {
    log.info("The method " + joinPoint.getSignature().getName() + "() begins with " + Arrays.toString(joinPoint.getArgs()));
    try
    {
        Object result = joinPoint.proceed();
        log.info("The method " + joinPoint.getSignature().getName() + "() ends with " + result);
        return result;
    }
    catch (IllegalArgumentException e)
    {
        log.error("Illegal argument " + Arrays.toString(joinPoint.getArgs()) + " in " + joinPoint.getSignature().getName() + "()");
        throw e;
    }
    }

}

解决方法

这些替代品之一呢？

A)一般执行切入点与包限制：

execution(* *(..)) &&
(
    within(com.abc.xyz..controller..*) ||
    within(com.abc.xyz..service..*) ||
    within(com.abc.xyz..dao..*)
)

B)封装限制执行切入点：

execution(* com.abc.xyz..controller..*(..)) ||
execution(* com.abc.xyz..service..*(..)) ||
execution(* com.abc.xyz..dao..*(..))

我喜欢B,顺便说一下,只是因为它有点更短,更容易阅读.你可能已经猜到了,符号是指“任何包或子包”,而在表达式后面的*表示“任何类中的任何方法”.
