1.注解对象:

@Retention(RetentionPolicy.RUNTIME)@Target(ElementType.FIELD)public @interface UserBeanAnno {	String desc() default "default desc";	String remark() default "default remark";}

2: 测试对象

public class UserBean {	@UserBeanAnno(desc = "this is id descn",remark="this is id remark")	public int id = 38;	@UserBeanAnno(remark = "th is uname rmark")	public String name = "用户名";	@UserBeanAnno(desc = "th is uage desc")	public String age = "22";	}

3: 测试:

public class UserBeanTest {	@Test	public void test() {		UserBean ub = new UserBean();		Class
     cls = ub.getClass();		  Field[] fields = cls.getDeclaredFields();		  for(Field field:fields){		   UserBeanAnno anno = field.getAnnotation(UserBeanAnno.class);			try {				System.out.println("属性值:"+field.get(ub));				System.out.println("注解值1:"+anno.desc());				System.out.println("注解值2:"+anno.remark());			} catch (Exception e) {				e.printStackTrace();			}		  }		}}

4:控制台输出的结果:

方法值:38注解值1:this is id descn注解值2:this is id remark方法值:用户名注解值1:default desc注解值2:th is uname rmark方法值:22注解值1:th is uage desc注解值2:default remark
