SpringBoot全局日志管理（AOP）

时间：2021-08-13 17:41:08

1、在pom.xml中引入aop的jar包

<dependency>

    <groupId>org.springframework.boot</groupId>

    <artifactId>spring-boot-starter-aop</artifactId>

</dependency>

2、创建WebLogAspect类

package com.cppdy.log;

import java.util.Enumeration;

import javax.servlet.http.HttpServletRequest;

import org.aspectj.lang.JoinPoint;

import org.aspectj.lang.annotation.AfterReturning;

import org.aspectj.lang.annotation.Aspect;

import org.aspectj.lang.annotation.Before;

import org.aspectj.lang.annotation.Pointcut;

import org.springframework.stereotype.Component;

import org.springframework.web.context.request.RequestContextHolder;

import org.springframework.web.context.request.ServletRequestAttributes;

@Aspect

@Component

public class WebLogAspect {

    @Pointcut("execution(public * com.cppdy.controller..*.*(..))")

    public void webLog() {

    }

    @Before("webLog()")

    public void doBefore(JoinPoint joinPoint) throws Throwable {

        // 接收到请求，记录请求内容

        ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();

        HttpServletRequest request = attributes.getRequest();

        // 记录下请求内容

        System.out.println("URL:" + request.getRequestURL().toString());

        System.out.println("HTTP_METHOD:" + request.getMethod());

        System.out.println("IP:" + request.getRemoteAddr());

        Enumeration<String> enu = request.getParameterNames();

        while (enu.hasMoreElements()) {

            String name = enu.nextElement();

            System.out.println("name:" + name + ",value:" + request.getParameter(name));

        }

    }

    @AfterReturning(returning="ret",pointcut="webLog()")

    public void doAfterReturning(Object ret)throws Throwable {

        //处理完请求，返回内容

        System.out.println("RESPONSE："+ret);

    }

}

3、访问login方法测试全局日志管理功能
