Java - Error: Attribute value must be constant
Error: Attribute value must be constant

Attribute value must be constant. 属性的值必须要是Constant.
如,在Annotation的接口中的值,但是字符串数组不能指定为Constant,Java中static final。
只能把纯字符设置为Constant,因此只能按如下使用:
public @interface SampleAnnotation {
String[] sampleValues();
}
public class Values {
public static final String v1 = "A";
public static final String v2 = "B";
@SampleAnnotation(sampleValues = { v1, v2 })
public void foo() {
}
}数组无法进行常量化,只能使用字符常量。参考: http://stackoverflow.com/questions/2065937/how-to-supply-value-to-an-annotation-from-a-constant-java
