    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;

    @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
