在 CXF 休息服务中访问 post 方法时出现问题

Question

我正在尝试使用 CXF 3.1.2 创建一个简单的 Restful Web 服务和客户端，如下所示，

服务：

package com.rs.sample;

    import javax.jws.WebService;
    import javax.ws.rs.Consumes;
    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.MediaType;

    public class GenServiceImpl  {

    @GET
    @Produces(MediaType.TEXT_PLAIN)
    @Consumes(MediaType.TEXT_PLAIN)
    @Path("/login/{ext}")
    public String login(@PathParam("ext") Integer ext) {
    return "LoggedIn";
    }

    @POST
    @Produces(MediaType.TEXT_PLAIN)
    @Consumes(MediaType.TEXT_PLAIN)
    @Path("/logout/{ext}")
    public String logout(@PathParam("ext") Integer ext) {
    return "LoggedOut";
    }
    }

客户：

import javax.ws.rs.core.MediaType;
    import javax.ws.rs.core.Response;
    import org.apache.cxf.jaxrs.client.WebClient;
    public class TestClient {
    static final String REST_URI = "http://localhost:8080/RestfulSample/Restful";
    public static void main(String[] args) {
    WebClient client = WebClient.create(REST_URI);


    /*
    //Get
    client.path("login").path(new Integer(1234)).accept(MediaType.TEXT_PLAIN);
    String loginResponse = client.get(String.class);
    System.out.println(loginResponse); */

    //Post
    client.path("logout").accept(MediaType.TEXT_PLAIN);
    String logoutResponse = client.post("1024").toString();
    System.out.println(logoutResponse);
    }

我在访问 login(Get) 方法时没有问题，它按预期工作。但是当我尝试访问注销（Post）方法时，出现以下错误，

        WARNING: No operation matching request path "/RestfulSample/Restful/agentLogout" is found, Relative Path: /agentLogout, HTTP Method: POST, ContentType: application/xml, Accept: text/plain,. Please enable FINE/TRACE log level for more details.

你能纠正我的错误吗

谢谢，

Answer 1

@Path("/logout/{ext}")。 /logout 之后需要另一个路径段。 {ext} 的值应该是

client.post("1024") 是请求的正文。 @PathParam是URI，所以URI路径需要加上1024，即path("logout").path("1024")。现在路径中没有 1024，则端点不存在（因此为 404）。

如果想把数据放在POSTbody里，那就改成@Path("/logout")，取出@PathParam，方法参数类型为String .您将需要自己解析它
