我正在尝试结合使用 Spring WebMVC 和 Apache CXF，但找不到该服务。为什么？

Question

我正在尝试使用 spring-WebMVC 和 apache CXF 设置一个项目，但如果我尝试调用 Web 服务，总是会出现一条消息告诉我："No service was found."

在apache的tomcat日志中，有一个警告：

org.apache.cxf.transport.servlet.ServletController invoke
WARNING: Can't find the request for 
http://localhost:8080/HelloWebService/rs/user-service/users's Observer

项目配置如下：

我正在使用这个 index.jsp 作为 webapp 的第一页。 index.jsp 包含以下代码：

<html>
<body>
    <h2>CXF RESTful services and Spring-WebMVC Test page</h2>
    <a href="rs/user-service/users">get all users</a>
    <br />
</body>
</html>

restful 网络服务如下所示：

package org.home.playground.interfaces;

import java.io.IOException;
import javax.servlet.http.HttpServletResponse;
import javax.ws.rs.Consumes;
import javax.ws.rs.FormParam;
import javax.ws.rs.GET;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
import javax.ws.rs.core.Context;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;
import org.home.playground.apputils.UserCollection;
import org.home.playground.models.User;

@Path("/user-service/")
@Produces("application/xml")
public interface IUserService {

    @GET
    @Path("/users")
    @Produces({"application/xml", "application/json"})
    public UserCollection getUsers();

    @GET
    @Path("/user/{id}")
    public User getUser(@PathParam("id") Integer id);

    @GET
    @Path("/users/bad")
    public Response getBadRequest();

    @POST
    @Path("/new")
    @Produces(MediaType.TEXT_HTML)
    @Consumes(MediaType.APPLICATION_FORM_URLENCODED)
    public void newUser(
            @FormParam("id") Integer id,
            @FormParam("name") String name,
            @Context HttpServletResponse servletResponse
    ) throws IOException;


}

我的 Spring-webMVC 控制器看起来像这样：

package org.home.playground.web.controllers;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

@Controller
public class HelloWorldController {

    @RequestMapping("/")
    protected ModelAndView showHelloWorldView(HttpServletRequest request, HttpServletResponse response) throws Exception {

        ModelAndView model = new ModelAndView("index");

        return model;
    }
    @RequestMapping("/postUser")
    protected ModelAndView postUserForm(HttpServletRequest request, HttpServletResponse response) throws Exception {

        ModelAndView model = new ModelAndView("postUser");

        return model;
    }
}

你知道为什么我不能调用网络服务吗？是否可以将 Spring-WebMVC 与 apache CXF 结合使用，或者这些框架在一个项目中不兼容？如果您需要更多信息，请告诉我，我会提供。非常感谢您的帮助，并提前致谢。

Answer 1

我已将项目拆分为 2 个项目。一个项目包含 Web 服务内容，另一个项目包含 Spring WebMVC 内容。我不确定是否有另一种可能性来解决这个问题，但它是这样工作的。
