        test_RestWebservice
         
      
     

3. 修改web.xml文件

       
      
       Archetype Created Web Application
        
          
       
        contextConfigLocation
           
       
        /WEB-INF/transport-servlet.xml
         
        
          
       
        transport
           
       
        org.springframework.web.servlet.DispatcherServlet
           
       
        1
         
        
          
       
        transport
           
       
        /
         
        
          
       
        CXFServlet
           
       
        org.apache.cxf.transport.servlet.CXFServlet
           
       
        2
         
        
          
       
        CXFServlet
           
       
        /userService/*
         
        
          
       
        org.springframework.web.context.ContextLoaderListener
         
      
     

4. 添加Spring配置文件transport-servlet.xml

5. 建立实体类User，添加注解@XmlRootElement(name = "User")

否则会出错：No message body writer has been found for response class User.

package com.rminfo.controller;import javax.xml.bind.annotation.XmlAccessType;import javax.xml.bind.annotation.XmlAccessorType;import javax.xml.bind.annotation.XmlRootElement;import javax.xml.bind.annotation.XmlType;/** * Created by carl on 2016/6/23. */@XmlRootElement(name = "User")public class User {    private String userId;    private String nickname;    public String getUserId() {        return userId;    }    public void setUserId(String userId) {        this.userId = userId;    }    public String getNickname() {        return nickname;    }    public void setNickname(String nickname) {        this.nickname = nickname;    }    @Override    public String toString() {        return "User{" +                "userId='" + userId + '\'' +                ", nickname='" + nickname + '\'' +                '}';    }}

6. WebService接口类添加注解，以及其实现

package com.rminfo.controller;import javax.ws.rs.*;import javax.ws.rs.core.MediaType;/** * Created by carl on 2016/6/23. */public interface UserService {    @GET    @Produces(MediaType.APPLICATION_JSON)    @Path("/searchUser/{id}")    public User searchUser(@PathParam("id") String userId);}

7. 测试是否发布成功：http://localhost:8080/test_RestWebservice/userService

出现上述画面说明发布成功。
