Ilog.java

自定义注解

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 "";
