我想知道是否有办法为 Preon 的单个类使用多个 @ImportStatic 注释？

我试过了：

@ImportStatic(classA.class)
@ImportStatic(classB.class)

// Also tried:

@ImportStatic(classA.class classB.class)

// And: 
@ImportStatic(classA.class,classB.class)

然而，这些都不是有效的......

我有一个规范，要求我查看外部（父）类的枚举值（classA），如果它与特定值匹配，那么我还必须对其他对象的枚举值之一进行枚举检查（ classB) 在继续阅读下一个字段之前。

编辑：这是我第一次尝试解决方案，基本上是复制 ImportStatic 并制作 ImportStatic2 注释......必须看看它的效果如何。

它使用如下语法显示：

@ImportStatic({First.class,Second.class})
