Question

我正在尝试制作一个简单的rest-api，它将返回JSON中的值。

我的服务等级是：-

import java.util.List;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;


@Path("/UserService") 
public class UserService { 

@GET
@Path("test")
@Produces(MediaType.APPLICATION_JSON)
public User getMyBean() {
   User oUser = new User(); 
   oUser.setName("Srijib");
   oUser.setId(7);
   oUser.setProfession("Student");
   return oUser;
}}

用户类别：-

import java.io.Serializable;  
import javax.xml.bind.annotation.XmlElement; 
import javax.xml.bind.annotation.XmlRootElement; 
@XmlRootElement(name = "user") 

public class User implements Serializable {  
   private static final long serialVersionUID = 1L; 
   private int id; 
   private String name; 
   private String profession; 
   public int getId() { 
      return id; 
   }  
   @XmlElement 
       public void setId(int id) { 
      this.id = id; 
   } 
   public String getName() { 
      return name; 
   } 
   @XmlElement
   public void setName(String name) { 
      this.name = name; 
   } 
   public String getProfession() { 
      return profession; 
   } 
   @XmlElement 
   public void setProfession(String profession) { 
      this.profession = profession; 
   }   
}

由于是第一次创建，所以我可能添加了一些根本不需要的jar。请提出同样的建议。

我的web.xml

<?xml version = "1.0" encoding = "UTF-8"?> 
<web-app xmlns:xsi = "http://www.w3.org/2001/XMLSchema-instance"  xmlns="http://java.sun.com/xml/ns/javaee"  
   xsi:schemaLocation="http://java.sun.com/xml/ns/javaee  
   http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"  
   id = "WebApp_ID" version = "3.0"> 
   <display-name>UserManagement</display-name> 
   <servlet> 
      <servlet-name>Jersey RESTful Application</servlet-name> 
      <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class> 
      <init-param> 
         <param-name>jersey.config.server.provider.packages</param-name>

   </servlet> 
   <servlet-mapping> 
      <servlet-name>Jersey RESTful Application</servlet-name> 
      <url-pattern>/rest/*</url-pattern> 
   </servlet-mapping>   
</web-app>

This is my server configuration

我正在尝试使用以下URL访问：- http://localhost:8080/UserManagement/rest/UserService/test

我尝试访问URL时遇到的错误是：-
