根据JAXRS规范，@ApplicationPath可以用在接口(interface)上吗？
import javax.ws.rs.ApplicationPath;
@ApplicationPath("/")
public interface TestRes {
}
编译器对此没有问题。但这是好方法吗？
最佳答案
ApplicationPath文档清楚地说它只适用于 javax.ws.rs.core.Application 的 subclass 所以如果你在接口(interface)上应用它不会工作，所以当你部署你最终可能会出现此错误消息 The ResourceConfig instance does not contain any root resource classes."
Identifies the application path that serves as the base URI for all resource URIs provided by Path.May only be applied to a subclass of Application.
The @ApplicationPath annotation is used to define the URL mapping for the application. The path specified by @ApplicationPath is the base URI for all resource URIs specified by @Path annotations in the resource class. You may only apply @ApplicationPath to a subclass of javax.ws.rs.core.Application.
