我正在传递JSON数据，比如

{
    "empname" : "seo"
}  

到POST url，但返回415错误，即不支持的媒体类型
排除故障后，我发现内容类型在poster extension中应为“application/json”，我尝试了相同的方法，但没有成功
下面是我的服务代码

package webService;

import java.sql.Connection;
import java.util.ArrayList;

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;
import javax.ws.rs.core.Response;

import com.google.gson.Gson;

import dao.Database;
import dao.Project;
import dto.FeedObjects;
import model.ProjectManager;


@Path("/WebService")
public class FeedService 
{
    @GET
    @Path("/GetFeeds")
    @Produces("application/json")
    public String feed()
    {
    String feeds = null;
    try
    {
    ArrayList<FeedObjects> feedData = null;
    ProjectManager projectManager= new ProjectManager();
    feedData = projectManager.GetFeeds();
    Gson gson = new Gson();
    System.out.println(gson.toJson(feedData));
    feeds = gson.toJson(feedData);
    }

    catch (Exception e)
    {
    System.out.println("Exception Error"); //Console 
    }
    return feeds;
    }

    @GET
    @Path("/insert/{empname}/{empsalary}")

    public String insertEmpName(@PathParam("empname") String empname,@PathParam("empsalary") String empsalary) {

        String result = "Employee Insertion Failed!!!!";
        try {

            Database database = new Database();
            Connection connection = database.Get_Connection();

            Project n = new Project();
            boolean b = n.insertEmpName(connection, empname,empsalary);

            if (b == true) {
                result = "Employee Added SuccessFully!!!!";

            } else {
                result = "Employee Already Exists!!!";
            }

        } catch (Exception e) {
            System.out.println(e);
        }

        return result;

    }

    @POST
    @Path("/justTesting")
    @Consumes(MediaType.APPLICATION_JSON)
    public Response myresponse(FeedObjects fb)
    {
        System.out.println("Name is "+fb.getEmpname());
        return Response.status(201).entity("Tested !!").build();

    }


}  

这是我的类，包含变量的setter和getter，我将它们作为参数传递给上面的方法，并使用它的对象（即fb）调用它们

package dto;

public class FeedObjects
{

private String empname;
private String empsalary;
public FeedObjects() {
    // TODO Auto-generated constructor stub
}
public String getEmpname() {
    return empname;
}
public void setEmpname(String empname) {
    this.empname = empname;
}
public String getEmpsalary() {
    return empsalary;
}
public void setEmpsalary(String empsalary) {
    this.empsalary = empsalary;
}

}

所以请帮我解决这个错误。我是JavaRESTWeb服务的新手，但我正在努力解决这个问题。
