我通过反射创建我的枚举,因为我为每个枚举添加了一个实现抽象工厂的内部类.现在我想访问这个内部类以调用该方法:
@Factory(FooFactory.class) public enum Foo { FOO,BAR; public class FooFactory implements AbstractFactory<Foo> { public Foo create(String value) { return valueOf(value.toUpperCase()); } } }
@Factory的定义是:
@Retention(RetentionPolicy.RUNTIME) public @interface Factory { Class<?> value(); }
但是,有了这个,我收到以下错误:
Class cannot be resolved to a type FooFactory.java
当我尝试@Factory(Foo $FooFactory.class)时,我收到错误:
The nested Foo$FooFactory cannot be referneced using its binary name.
那么甚至可以引用嵌套类吗?
