Question

我使用Jersey网站上的一个示例在NetBeans JEE 8.1中构建了一个简单的测试项目。我可以附加调试器并观察正在执行的服务代码并生成带有JSON内容的CREATED响应。发送到浏览器的是404而不是响应。我已经简化了服务代码以消除除REST相关线之外的其他问题。该应用程序的代码是：

package com.domenix.resttestproject;

import java.util.HashSet;
import java.util.Set;
import javax.ws.rs.ApplicationPath;
import javax.ws.rs.core.Application;

/**
 *
 * @author tswanson
 */
@ApplicationPath("/test")
public class TestApplication extends Application
{

  /**
   *
   * @return
   */
  @Override
  public Set<Class<?>> getClasses()
  {
    final Set<Class<?>> retValue = new HashSet<Class<?>>();
    retValue.add( SvcsService.class );
    return( retValue );
  }
}

该服务的代码是：

package com.domenix.resttestproject;

import javax.json.Json;
import javax.json.JsonObjectBuilder;
import javax.ws.rs.Consumes;
import javax.ws.rs.FormParam;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.Response;

import java.util.concurrent.atomic.AtomicInteger;
import javax.json.JsonObject;
import javax.servlet.http.HttpServletResponse;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response.ResponseBuilder;

/**
 *
 * @author tswanson
 */
@Path("/svcs")
public class SvcsService
{
  AtomicInteger idGen = new AtomicInteger(1);

  @Path("/create")
  @Consumes("application/x-www-form-urlencoded")
  @Produces("application/json")
  public Response createUser( @FormParam("userid") String userId ,
                              @FormParam("password") String pwd ,
                              @FormParam("role") String role )
  {
    JsonObjectBuilder bldr = Json.createObjectBuilder();
    JsonObject resp = bldr.add( "userIdx" , idGen.getAndIncrement() )
                          .add( "userName" , userId )
                          .add( "pwd" , pwd )
                          .add( "role" , role ).build();
    ResponseBuilder respBldr = Response.ok( resp.toString() ,
                   MediaType.APPLICATION_JSON_TYPE );
    respBldr.status( HttpServletResponse.SC_CREATED );
    Response myResp = respBldr.build();

    return( myResp );
  }
}

web.xml文件是：

映射中似乎缺少某些东西，它是什么？

感谢。

即使调试显示响应正确，也找不到tomcat7上的jersey servlet
