SpringBoot全局日志管理（AOP）

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
