技術標籤：javaspringboot日誌aop

主要是用來記錄請求引數和響應結果，方便部署到伺服器上以後可以通過日誌來查詢問題：
首先新增如下依賴：

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

然後編寫一個aop的配置類：

package com.sztf.shidaikeyi.config;

import cn.hutool.extra.servlet.ServletUtil;
import cn.hutool.json.JSONUtil;
import lombok.extern.slf4j.Slf4j;
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.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;

/**
 * 列印引數日誌切面類
 *
 * @Author: ljp
 * @CreateDate: 2021/2/2 14:03
 */
@Aspect
@Component
@Slf4j
public class LogAspect {

    @Pointcut("execution(public * com.sztf.shidaikeyi.*.*(..))")
    public void getMethodName() {

    }

	//在這裡指定切入點 條件一：com.sztf.shidaikeyi包下 條件二：帶有@RestController註解
    @Pointcut("within(com.sztf.shidaikeyi..*) && @within(org.springframework.web.bind.annotation.RestController)")
    public void printParams() {

    }

    /**
     * 列印請求引數
     *
     * @param joinPoint
     */
    @Before(value = "printParams()")
    public void paramsLog(JoinPoint joinPoint) {
        ServletRequestAttributes requestAttributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
        HttpServletRequest request = requestAttributes.getRequest();
        log.info("sign -- {}", joinPoint.getSignature());
        log.info("請求地址:" + request.getRequestURL().toString());
        log.info("請求方式:" + request.getMethod());
        if ("POST".equals(request.getMethod())) {
            log.info("請求引數：" + Arrays.toString(joinPoint.getArgs()));
        } else {
            log.info("請求引數：{}", ServletUtil.getParamMap(request));
        }
    }

    /**
     * 列印響應內容
     *
     * @param o
     */
    @AfterReturning(returning = "o", pointcut = "printParams()")
    public void methodAfterReturn(Object o) {
        log.info(JSONUtil.parse(o).toJSONString(1));
    }
}

新增以後就可以列印專案了，還是比較簡單的，在這裡記錄一下
