14+
* 　　　　1.CONSTRUCTOR:用于描述构造器
15+
* 　　　　1.CONSTRUCTOR:用于描述构造器
16+
* 　　　　2.FIELD:用于描述域
17+

18+
* 　　　　4.METHOD:用于描述方法
19+
* 　　　　5.PACKAGE:用于描述包
20+
* 　　　　6.PARAMETER:用于描述参数
21+
* 　　　　7.TYPE:用于描述类、接口(包括注解类型) 或enum声明
22+
*
23+
* 2.@Retention
24+
* 指注解的生命期
25+
* 取值（RetentionPoicy）有：
26+
* 　　　　1.SOURCE:在源文件中有效（即源文件保留）
27+
* 　　　　2.CLASS:在class文件中有效（即class保留）
28+
* 　　　　3.RUNTIME:在运行时有效（即运行时保留）
29+
*
30+
* 3.@Documented
31+
* 指注解是否可以有文档化
32+
* Documented是一个标记注解，没有成员；
33+
* 标记是否可被javadoc此类的工具文档化
34+
*
35+
* 4.@Inherited
36+
* 定义该注释和子类的关系，即是否允许子类继承该注解
37+
*
38+
* 自定义注解类编写的一些规则:
39+
* 1. Annotation型定义为@interface, 所有的Annotation会自动继承java.lang.Annotation这一接口,并且不能再去继承别的类或是接口.
40+
* 定义注解格式：
41+
* 　public @interface 注解名 {定义体}
42+
* 2. 参数成员只能用public或默认(default)这两个访问权修饰
43+
* 3. 参数成员只能用基本类型byte,short,char,int,long,float,double,boolean八种基本数据类型和String、Enum、Class、
44+
* Annotation等数据类型,以及这一些类型的数组.
45+
* 4. 要获取类方法和字段的注解信息，必须通过Java的反射技术来获取 Annotation对象,因为你除此之外没有别的获取注解对象的方法
46+
* 5. 注解也可以没有定义成员, 不过这样注解就没啥用了
47+
* PS:自定义注解需要使用到元注解
