前言：
任何一个项目都会有一个用户操作日志（也叫行为日志）的模块，它主要用来记录某个用户做了某个操作，当出现操作失败时，通过日志就可以快速的查找是哪个用户在哪个模块出现了错误，以便于开发人员快速定位问题所在。
实现这一功能一般有两种方法：
具体实现步骤
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-aop</artifactId>
</dependency>`
设计操作日志记录表
新增日志实体类、dao层 接口
自定义操作日志记录的注解

*/
@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 {
String operModul() default ""; // 操作模块
String operType() default ""; // 操作类型
String operDesc() default ""; // 操作说明
