Spring 如何整合jersey+；春季jpa？

在与jersey+jpa集成时，我遇到了与映射资源有关的错误，并且在控制器中找不到请求。以下是我在运行应用程序时遇到的错误

10:43:34.616 [http-nio-8080-exec-2] DEBUG org.springframework.web.servlet.DispatcherServlet - DispatcherServlet with name 'dispatcher' processing GET request for [/xptraining/]
10:43:34.618 [http-nio-8080-exec-2] WARN org.springframework.web.servlet.PageNotFound - No mapping found for HTTP request with URI [/xptraining/] in DispatcherServlet with name 'dispatcher'
10:43:34.618 [http-nio-8080-exec-2] DEBUG org.springframework.web.servlet.DispatcherServlet - Successfully completed request
