小编use*_*023的帖子

我正在尝试用Java编写REST Web服务(使用Netbeans,Glassfish和Jersey).

我写了一个小应用程序,它的工作原理.但后来我尝试了以下内容:

package service;

import java.util.logging.Logger;
import javax.ws.rs.*;
import javax.ws.rs.core.Response;
import converter.FlyedpConverter;

   public Response get(@PathParam("date") String date) throws IOException {
      FlysCombination comb = new FlysCombination();
      FlysCombination x = FlysCombination.instance();
      comb = x.getcomb(date);

      System.out.println(comb.toString());

      if (comb == null) {
         return Response.status(Response.Status.NOT_FOUND).build();
      }
      return Response.ok(comb).build();
   }
}

我的班级FlysCombination:

package entities;

import converter.FlyedpConverter;
import java.util.ArrayList;

public class FlysCombination {

   public FlysCombination() {}

   public static FlysCombination flycomb …
