類型註釋值

Question

接口：

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

聲明：

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

我怎能類接口類型正確的屬性？

Answer 1

你忘了花括號：

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"; 
}
