首先写个注解类，用来标识方法满足切入点
package com.enation.framework.database;
import java.lang.annotation.Documented;
import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;
/**
* 表示对标记有xxx注解的类,做代理 注解@Retention可以用来修饰注解，是注解的注解，称为元注解。
* Retention注解有一个属性value，是RetentionPolicy类型的，Enum RetentionPolicy是一个枚举类型，
* 这个枚举决定了Retention注解应该如何去保持，也可理解为Rentention 搭配
* RententionPolicy使用。RetentionPolicy有3个值：CLASS RUNTIME SOURCE
* 用@Retention(RetentionPolicy
* .CLASS)修饰的注解，表示注解的信息被保留在class文件(字节码文件)中当程序编译时，但不会被虚拟机读取在运行的时候；
* 用@Retention(RetentionPolicy.SOURCE
* )修饰的注解,表示注解的信息会被编译器抛弃，不会留在class文件中，注解的信息只会留在源文件中；
* 用@Retention(RetentionPolicy.RUNTIME
* )修饰的注解，表示注解的信息被保留在class文件(字节码文件)中当程序编译时，会被虚拟机保留在运行时，
* 所以他们可以用反射的方式读取。RetentionPolicy.RUNTIME
* 可以让你从JVM中读取Annotation注解的信息，以便在分析程序的时候使用.
*
* 类和方法的annotation缺省情况下是不出现在javadoc中的，为了加入这个性质我们用@Documented
* java用 @interface Annotation{ } 定义一个注解 @Annotation，一个注解是一个类。
* @interface是一个关键字，在设计annotations的时候必须把一个类型定义为@interface，而不能用class或interface关键字
