我正在开发一个 ejb 项目，我需要定义一组可以在整个项目中使用的常量，因此我创建了一个接口(interface)来保存我的常量集，我的问题是有更好的方法吗在Web项目中定义常量？
这是我的常量界面的示例:
public interface ejbConstant {
final String CONST23= "AB23";
final String CONST24= "AB24";
// ..........
}
感谢您的建议

Sonar已经相当不错了explanation of this with examples
根据《Effective Java》一书的作者 Joshua Bloch 的说法:
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.
