多个切面执行同一个方法

1.建立日志切面

import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import org.springframework.context.annotation.EnableAspectJAutoProxy;
import org.springframework.core.annotation.Order;
import org.springframework.stereotype.Component;

import java.lang.reflect.Method;

//开启AspectJ 自动代理模式,如果不填proxyTargetClass=true，默认为false，
@EnableAspectJAutoProxy(proxyTargetClass = true)
@Component
@Aspect
@Order(1)
public class ControllerLogAspectConfig {
    @Around("execution(* com.g2.order.server.controller.*.*(..))")
    public Object handleControllerMethod(ProceedingJoinPoint proceedingJoinPoint) throws Throwable {
        System.out.println("进入日志切面");

        //获取controller对应的方法.
        org.aspectj.lang.reflect.MethodSignature methodSignature = (org.aspectj.lang.reflect.MethodSignature) proceedingJoinPoint.getSignature();
        //获取方法所在的类(controller)
        Class beanType = methodSignature.getDeclaringType();
        //获取方法
        Method method = methodSignature.getMethod();

        //获取方法参数列表(无需处理讨厌的流了)
        Object[] args = proceedingJoinPoint.getArgs();
        for (Object arg : args) {
            //获取参数的类型与值
            System.out.println(arg.getClass().getName());
            System.out.println("arg is " + arg);
        }


        System.out.println("进入其他切面..");
        Object obj = proceedingJoinPoint.proceed();
        //获取返回值的类型,与 Method.getReturnType()一致
        Class responseClass=obj.getClass();

        //方法的返回值是:
        System.out.println("response is " + obj);
        System.out.println("业务完成,日志已记录");
        return obj;
    }
}

 

2.建立执行时间切面 

import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.Signature;
import org.aspectj.lang.annotation.After;
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.beans.factory.annotation.Autowired;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.ServletComponentScan;
import org.springframework.context.annotation.AnnotationConfigApplicationContext;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.EnableAspectJAutoProxy;
import org.springframework.core.Ordered;
import org.springframework.core.annotation.Order;
import org.springframework.stereotype.Component;

import java.lang.reflect.Method;

import javax.annotation.Resource;

//开启AspectJ 自动代理模式,如果不填proxyTargetClass=true，默认为false，
@Component
@Aspect
@Order(Ordered.LOWEST_PRECEDENCE)
public class ControllerTimeAspectConfig {
    @Around("execution(* com.g2.order.server.controller.*.*(..))")
    public Object handleControllerMethod(ProceedingJoinPoint proceedingJoinPoint) throws Throwable {
        System.out.println("进入时间切面,执行before..");


        System.out.println("进入业务执行..");
        long startTime = System.currentTimeMillis();

        Object obj = proceedingJoinPoint.proceed();

        System.out.println("time aspect 耗时" + (System.currentTimeMillis() - startTime));


        System.out.println("业务完成,执行时间已记录");
        return obj;
    }
}
