推荐答案
@Documented 是元注解。定义一个注释的时候，要确保使用注释显示这在他们生成的JavaDoc类你申请 @Documented 。我从来没见过多大用处的，但there在这里一个例子。前面一个问题表明它doesn't在Eclipse 自动工作，但我已经在Eclipse 3.6的测试，而我的注释出现在JavaDoc弹出与否我附上 @Documented 注释给他们
@Documented is a meta-annotation. You apply @Documented when defining an annotation, to ensure that classes using your annotation show this in their generated JavaDoc. I've not seen much use of it, but there is an example here. An earlier question suggests that it doesn't work automatically in Eclipse, but I've tested in Eclipse 3.6, and my annotations appear in the JavaDoc popups whether or not I attach the @Documented annotation to them.
下面是春天，这确保了交易方法是在JavaDoc标记为这样一个例子：
Here's an example from Spring, which ensures that transactional methods are marked as such in the JavaDoc:
@Target({ElementType.METHOD, ElementType.TYPE})
@Retention(RetentionPolicy.RUNTIME)
@Inherited
@Documented
public @interface Transactional {
