eclipse - 为什么我收到 javax.ws.rs.WebApplicationException

Question

我正在尝试编写一个简单的项目。我正在使用tomee。 Tomee 工作正常，但我无法访问我的项目。当我尝试从浏览器访问我的项目时，Eclipse 控制台给出以下错误。

Answer 1

如果您不指定应用程序，休息服务似乎会接管您的完整上下文，因此将下面的类添加到您的上下文中，它应该可以工作(它对我有用)。

@ApplicationPath("/rest") 
public class ApplicationConfig extends Application { 
}

更新

或者，为了不在您的休息网址中出现丑陋的 /rest 部分:而不是为您的主 Web 应用程序指定 urlPatterns={"/*"} (这与默认的休息应用程序冲突)您可以缩小范围，例如对于我的 vaadin 来说，到目前为止这是有效的:

@WebServlet(urlPatterns = {"", "/VAADIN/*", "/UIDL/*", "/HEARTBEAT/*"}

因此，您未为主应用程序更精确指定的所有内容都将转到其余应用程序。
