java - @Category 注释中的不止一种类型

Question

GWT AutoBean page说:

The @Category annotation may specify more than one category type.

以下语法给出标记“，”，/预期的语法错误:

@Category(FooCategory.class, BarCategory.class)
public interface FooBarFactory extends AutoBeanFactory { 
    ...
}

指定多个类别类的语法是什么？

Answer 1

用{和}包裹参数

@Category({FooCategory.class, BarCategory.class})
public interface FooBarFactory extends AutoBeanFactory { 
    ...
}
