Spring Boot添加AOP日志

Spring Boot添加AOP日志

• 添加aop包

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

• 编写切面配置类

package com.example.demo.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;

/**
 * 统一处理web请求日志
 */
@Aspect
@Component
public class WebLogAspect {
    private Logger logger = LoggerFactory.getLogger(WebLogAspect.class);

    @Pointcut("execution(public * com.example.demo.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("{} => {}-{}:{}.{}({})", request.getRemoteAddr(), request.getMethod(),
                request.getRequestURL().toString(), joinPoint.getSignature().getDeclaringTypeName(),
                joinPoint.getSignature().getName(), 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);
    }
}

• 执行请求，日志打印
