我正在开发一个EJB项目，我需要定义一组常量，这些常量可以在整个项目中使用，所以我创建了一个保存常量集的接口我的问题是，有没有更好的方法来定义Web项目中的常量？

这是我不变界面的一个例子：

谢谢你的建议

声纳用例子对此有很好的解释

根据《有效Java》的作者Joshua Bloch

The constant interface pattern is a poor use of interfaces.

That a class uses some constants internally is an implementation
detail. Implementing a constant interface causes this implementation
detail to leak into the class's exported API. It is of no consequence
to the users of a class that the class implements a constant
interface. In fact, it may even confuse them. Worse, it represents a
commitment: if in a future release the class is modified so that it no
longer needs to use the constants, it still must implement the
interface to ensure binary compatibility. If a nonfinal class
implements a constant interface, all of its subclasses will have their
namespaces polluted by the constants in the interface.
