日志系列---【SpringBoot使用Aop实现格式化日志】

作者:互联网

1.最终实现效果

 

2.在pom中引入Aop依赖(可以先写个@Aspect注解,如果不报错,说明项目中引入过aop依赖了,不用再重复引入下面的依赖)

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-aop</artifactId>
</dependency>

3.这里我项目中用了swagger,为了不重复写注释,我直接用了@ApiOperation注解作为切点,当然,也可以自定义注解,把ApiOperation换成自定义的就行了。

package com.system.annotation.Handler;

import io.swagger.annotations.ApiOperation;
import lombok.extern.slf4j.Slf4j;
import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.*;
import org.aspectj.lang.reflect.MethodSignature;
import org.springframework.stereotype.Component;
import org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.ServletRequestAttributes;

import javax.servlet.http.HttpServletRequest;
import java.lang.reflect.Method;

@Slf4j
@Aspect
@Component
public class LogHandler {

    @Pointcut("@annotation(io.swagger.annotations.ApiOperation)")
    public void webLog() {
    }

    @Around("webLog()")
    public Object doAround(ProceedingJoinPoint proceedingJoinPoint) throws Throwable {
        long startTime = System.currentTimeMillis();
        Object result = proceedingJoinPoint.proceed();
        //打印出参
        log.info("Response Args : {}", result);
        //执行耗时
        log.info("exe-time      : {} ms", System.currentTimeMillis() - startTime);
        log.info("============================================End==================================================="+System.lineSeparator());
        return result;
    }

    @Before("webLog()")
    public void doBefore(JoinPoint joinPoint){
        ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
        HttpServletRequest request = attributes.getRequest();
        MethodSignature methodSignature = (MethodSignature) joinPoint.getSignature();
        Method method = methodSignature.getMethod();
        ApiOperation annotation = method.getAnnotation(ApiOperation.class);
        String msg = annotation.value();
        log.info(System.lineSeparator());
        log.info("============================================Start=================================================");
        //打印请求的url
        log.info("URL           : {}",request.getRequestURL().toString());
        log.info("Description   : {}",msg);
        log.info("HTTP Method   : {}",request.getMethod());
        log.info("Class Method  : {},{}",joinPoint.getSignature().getDeclaringTypeName(),joinPoint.getSignature().getName());
        log.info("IP            : {}",request.getRemoteAddr());
        Object[] args = joinPoint.getArgs();
        log.info("Request Args  : {}",args);
    }

    @After("webLog()")
    public void doAfter() throws Throwable{
        log.info("==========================================Response=================================================");
    }
}

4.自定义注解(可以不自定义,我直接用的ApiOperation)

package com.jiulong.springboot_validator.annotation;

import java.lang.annotation.*;

@Retention(RetentionPolicy.RUNTIME)
@Target({ElementType.METHOD})
@Documented
public @interface WebLog {

    /**
     * 日志描述信息
     *
     * @return String
     */
    String value() default "";
}
