Springboot添加AOP打印请求参数

1. 引入依赖

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

2. 写切面

切面类需要加@Aspect和@Component注解

package com.test.demo.aspect;

import java.util.Map;

import javax.servlet.http.HttpServletRequest;

import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.AfterReturning;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.aspectj.lang.annotation.Pointcut;
import org.springframework.stereotype.Component;
import org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.ServletRequestAttributes;

import cn.hutool.core.date.DateUtil;
import cn.hutool.extra.servlet.ServletUtil;
import cn.hutool.json.JSONUtil;
import io.swagger.annotations.Api;
import lombok.extern.slf4j.Slf4j;

@Aspect
@Component
@Slf4j
public class LogPrintAspect {
    
    @Pointcut("execution(public * com.test.demo.*.*(..))")
    public void getMethodName() {
        
    }
    
    @Pointcut("within(com.test.demo..*) && @within(org.springframework.web.bind.annotation.RestController)")
    public void printParams() {
        
    }
    
    /**
     * 打印请求参数
     * @param joinPoint
     */
    @Before(value = "printParams()")
    public void paramsLog(JoinPoint joinPoint) {
        ServletRequestAttributes requestAttributes = 
                (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
         HttpServletRequest request = requestAttributes.getRequest();
         Class<?> targetClass = joinPoint.getTarget().getClass();
        if (targetClass.isAnnotationPresent(Api.class)) {
            Api swaggerApi = (Api) targetClass.getDeclaredAnnotation(Api.class);
            log.info("模块的中文汉字 {} , {}", swaggerApi.value(), swaggerApi.tags()[0]);
        }
        log.info("sign -- {}", joinPoint.getSignature());
        log.info("请求地址:" + request.getRequestURL().toString());
        log.info("请求方式:" + request.getMethod());
        Map<String, String> m = ServletUtil.getParamMap(request);
        log.info("请求参数：{}", m);
    }
    
    /**
     * 打印响应内容
     * @param o
     */
    @AfterReturning(returning = "o", pointcut = "printParams()")
    public void methodAfterReturing(Object o) {
        log.info(JSONUtil.parse(o).toJSONString(1));
    }
    
    
    /**
     * 打印方法耗时
     * @param joinPoint
     * @return
     * @throws Throwable
     */
    @Around("printParams()")
    public Object around(ProceedingJoinPoint joinPoint) throws Throwable{
        long startTime = DateUtil.current(false);
        log.info("执行方法：{},开始时间:{}" , joinPoint.getSignature().getName() , startTime);
        Object result = joinPoint.proceed();
        long endTime= DateUtil.current(false);
        log.info("执行方法：{}，结束时间:{} , 用时:{} 毫秒 , " , joinPoint.getSignature().getName() , endTime, endTime-startTime);
        return  result  ;
    }
