springboot整合日志功能_如何给spring boot项目添加日志功能

1、引入依赖

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

2、application.yml配置

# 日志配置
logging:
  level:
    com.xiaomin.page: debug

3、定义切面类

package com.xiaomin.page.aspect;
 
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;
 
import javax.servlet.http.HttpServletRequest;
import java.util.Arrays;
 
/**
 * @author 晓敏
 * @create 2020-03-26 15:11
 */
@Aspect
@Component
public class WebLog {
    private Logger logger = LoggerFactory.getLogger(WebLog.class);
 
    /**
     * 配置切入点
     */
    @Pointcut("execution(* com.xiaomin.page.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());
        logger.info("CLASS_METHOD : " + joinPoint.getSignature().getDeclaringTypeName() + "." + joinPoint.getSignature().getName());
        logger.info("ARGS : " + Arrays.toString(joinPoint.getArgs()));
    }
 
    @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);
    }
}

3、测试
