Spring Boot2.0之统一处理web请求日志

试问,你的项目中,如果有几万个方法,你还这么写log.info("name"+name+",age"+age )日志么?low~ 

    所以用AOP呀

1、首先创建个aop的包(aop的依赖jar包要在pom中搞定),把下面类,贴进去:

 

package com.toov5.aop;

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.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Component;
import org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.ServletRequestAttributes;

@Aspect
@Component
public class WebLogAspect {

    private static final Logger logger = LoggerFactory.getLogger(WebLogAspect.class);

    @Pointcut("execution(public * com.itmayiedu.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
        logger.info("URL : " + request.getRequestURL().toString());
        logger.info("HTTP_METHOD : " + request.getMethod());
        logger.info("IP : " + request.getRemoteAddr());
        Enumeration<String> enu = request.getParameterNames();
        while (enu.hasMoreElements()) {
            String name = (String) enu.nextElement();
            logger.info("name:{},value:{}", name, request.getParameter(name));
        }
    }

    @AfterReturning(returning = "ret", pointcut = "webLog()")
    public void doAfterReturning(Object ret) throws Throwable {
        // 处理完请求,返回内容
        logger.info("RESPONSE : " + ret);
    }
}

 

2、后端业务逻辑代码:

  

package com.toov5.ErrorCatch;


import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import lombok.extern.slf4j.Slf4j;



@RestController //以后经常做微服务异常捕获,要经常用到这个注解
@Slf4j
public class ErrorCatch {
    
    @RequestMapping("/getUser")
    public String getUser(int i ){
        int j = 1/i;    
        log.info("成功哈");
        return "返回"+j;
    }
    @RequestMapping("/getMember")
    public String getMember(String name, Integer age){
//        log.info("name"+name+",age"+age );//如果几万个方法都要写这个么? 所以用aop去统一处理
        return "okokok";
    }
    
    
}

 

3、启动类我做了一个小修改哈:

   

扩大了一下扫描范围

 

现在整个项目的目录结构是这样的:

 

 启动,请求:

 

 

 

 

可以看到控制台:

 

 

 小伙伴是不是很简单啊~

 后面会介绍:分布式日志收集系统,也是分布式解决方案的一种~有兴趣有的小伙伴可以自己看下
