1.存在的意义

  所日志记录，就是记录所有的操作，使领导对这个系统的流转了如指掌，同时要是系统出现了问题，也可以清楚找到问题的所在。

2. 界面展示

 技术分享

3. 主要代码分析（提供三种方法）

  3.1 方法一 使用aop实现

源码介绍:

01.首先在保证你的环境无误的情况下（我用的是ssh）

02.BussAnnotation.java  (自定义注解)

import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;

@Retention(RetentionPolicy.RUNTIME)
@Target({ ElementType.METHOD })
public @interface BussAnnotation {
    // 模块名
    String moduleName();
    // 操作内容 
    String option();
