springboot项目自定义切面增强方法功能（springboot记录日志）

说明

背景：记录系统接口日志入库，包含接口方法、入参、回参、响应时间、操作人、操作时间等信息。

方案：添加自定义切面处理

一、自定义切面注解

package com.gstanzer.supervise.annotation;

import com.gstanzer.supervise.enums.BusinessType;

import java.lang.annotation.*;

/**
 * 系统操作日志
 *
 * @author: tangbingbing
 * @date: 2023/12/15 15:25
 */
@Documented
@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.METHOD)
public @interface SysOperLog {
    /**
     * 接口名称
     */
    String name();

    /**
     * 接口功能
     */
    BusinessType businessType() default BusinessType.OTHER;

}

二、自定义切面

package com.gstanzer.supervise.aspect;


import cn.hutool.core.util.IdUtil;
import com.alibaba.fastjson.JSON;
