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:

Spring Boot2.0之统一处理web请求日志-LMLPHP

扩大了一下扫描范围

现在整个项目的目录结构是这样的:

Spring Boot2.0之统一处理web请求日志-LMLPHP

启动,请求:

Spring Boot2.0之统一处理web请求日志-LMLPHP

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
