springboot异步和切面_springboot日志切面通用类实例详解

1.pom.xml文件导入AOP依赖

org.springframework.boot

spring-boot-starter-aop

2.3.0.RELEASE

2.pom.xml导入Lombok依赖

org.projectlombok

lombok

true

package jmu.rjc.aspect;

import lombok.AllArgsConstructor;

import lombok.Data;

import lombok.NoArgsConstructor;

import lombok.ToString;

import org.aspectj.lang.JoinPoint;

import org.aspectj.lang.annotation.*;

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;

import javax.servlet.http.HttpServletRequest;

//日志切面

@Aspect

@Component

public class LogAspect {

private final Logger logger = LoggerFactory.getLogger(this.getClass());

//包名配置为自己的项目包名即可

@Pointcut("execution(* jmu.rjc.web.*.*(..))")

public void log(){}

@Before("log()")

public void doBefore(JoinPoint joinPoint){

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

HttpServletRequest request = attributes.getRequest();

String url = request.getRequestURL().toString();

String ip = request.getRemoteAddr();

String classMethod = joinPoint.getSignature().getDeclaringTypeName()+"."+joinPoint.getSignature().getName();

Object[] args = joinPoint.getArgs();

RequestLog requestLog = new RequestLog(url,ip,classMethod,args);

logger.info("Request : {}",requestLog);

}

@After("log()")

public void doAfter(){

logger.info("---------doAfter-------");

}

@AfterReturning(returning = "result",pointcut = "log()")

public void doAfterReturn(Object result){

logger.info("Result : {}"+result);

}

@Data

@ToString

@AllArgsConstructor

@NoArgsConstructor

private class RequestLog{

private String url;

private String ip;

private String classMethod;

private Object[] args;

}

}

3.关于Lombok的注意点

Lombok的使用大大简化了开发过程,提高了开发效率,但是也存在一些隐患.比如强行侵入jar包,JDK版本升级冲突,破坏部分封装性等缺陷,使用前最好和团队商量好
