Advices.java
注意切入点 所在包下要对不然启动不成功

Ilog.java
自定义注解
package com.baccarat.aop; import java.lang.annotation.ElementType; import java.lang.annotation.Documented; import java.lang.annotation.Retention; import java.lang.annotation.Target; import java.lang.annotation.RetentionPolicy; @Target({ElementType.PARAMETER, ElementType.METHOD}) @Retention(RetentionPolicy.RUNTIME) @Documented public @interface ILog { /** 要执行的操作类型比如:add操作 **/ public String operationType() default ""; /** 要执行的具体操作比如:添加用户 **/ public String operationName() default ""; }
service
自定义注解
结果
不忘初心
