一、自定义操作日志注解

import java.lang.annotation.*;

/**
 * 自定义操作日志注解
 *
 * @Author: change
 **/
@Target(ElementType.METHOD)//注解放置的目标位置即方法级别
@Retention(RetentionPolicy.RUNTIME)//注解在哪个阶段执行
@Documented
public @interface OperationLogAnnotation {

    // 操作模块
    String operModul() default "";

    // 操作类型
    String operType() default "";

    // 操作说明
    String operDesc() default "";
}

二、操作日志切面处理类

package com.lzby.tqj.annotation;

import cn.hutool.json.JSONUtil;
import com.lzby.tqj.common.IpUtils;

import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.annotation.AfterReturning;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Pointcut;
import org.aspectj.lang.reflect.MethodSignature;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import org.springframework.web.context.request.RequestAttributes;
import org.springframework.web.context.request.RequestContextHolder;

import java.util.Map;
import java.util.UUID;

@Component

    @Autowired
    SysIpLogMapper sysIpLogMapper;

    /**

     */
    @Pointcut("@annotation(com.lzby.tqj.annotation.OperationLogAnnotation)")
    public void operLogPoinCut() {
    }

    /**
     * 记录操作日志
     *
     * @param joinPoint 方法的执行点
     * @param result    方法返回值
     * @throws Throwable
     */
    @AfterReturning(returning = "result", value = "operLogPoinCut()")
    public void saveOperLog(JoinPoint joinPoint, Object result) throws Throwable {
        // 获取RequestAttributes
        RequestAttributes requestAttributes = RequestContextHolder.getRequestAttributes();
        // 从获取RequestAttributes中获取HttpServletRequest的信息
        HttpServletRequest request = (HttpServletRequest) requestAttributes.resolveReference(RequestAttributes.REFERENCE_REQUEST);
        try {
            //将返回值转换成map集合
            Map<String, String> map = (Map<String, String>) result;
            SysLog sysLog = new SysLog();
            // 从切面织入点处通过反射机制获取织入点处的方法
            MethodSignature signature = (MethodSignature) joinPoint.getSignature();
            //获取切入点所在的方法
            Method method = signature.getMethod();
            //获取操作
            OperationLogAnnotation annotation = method.getAnnotation(OperationLogAnnotation.class);
            if (annotation != null) {
                sysLog.setModel(annotation.operModul());
                sysLog.setType(annotation.operType());
                sysLog.setDescription(annotation.operDesc());
            }

            cn.hutool.json.JSONObject user = JSONUtil.parseObj(request.getHeader("userDetail"));
			
			//设置保存的日志信息
            sysLog.setId(UUID.randomUUID().toString());
            //操作用户
            sysLog.setSfzh(user.getStr("sfzh"));
            String userName = sysIpLogMapper.getUserName(user.getStr("sfzh"));
            sysLog.setName(userName);

            //操作IP
            sysLog.setIp(IpUtils.getIpAddr(request));
            //返回值信息
            sysLog.setResult(map.toString());
            sysLog.setTypeName(method.getName());
            //保存日志
            sysLogMapper.insert(sysLog);

        } catch (Exception e) {
            e.printStackTrace();
        }
    }
