包含字符串数组值的类型注释

Question

接口：

public @interface Types {
    String[] value();
}

声明：

@Types(TEST.T1, TEST.T2)
public class TEST{
    public static final String T1= "DAS";
    public static final String T2= "ABC";
}

如何正确地在类型界面中对属性进行分类？

Answer 1

你忘记了花括号：

public @interface Types {
    String[] value();
}

@Types({Test.T1, Test.T2}) // <- requires {} here because multiple values passed
public class Test{
    public static final String T1= "DAS";
    public static final String T2= "ABC";
}
