我正在使用Jersey服务和客户端.当我试图调用该服务时,我收到此错误：
Exception in thread "main" com.sun.jersey.api.client.UniformInterfaceException: GET http://localhost:8080/Maze/rest/service/overview?countryid=1 returned a response status of 204 No Content at com.sun.jersey.api.client.ClientResponse.getEntity(ClientResponse.java:528) at com.sun.jersey.api.client.ClientResponse.getEntity(ClientResponse.java:506) at com.sun.jersey.api.client.WebResource.handle(WebResource.java:674) at com.sun.jersey.api.client.WebResource.access$200(WebResource.java:74) at com.sun.jersey.api.client.WebResource$Builder.get(WebResource.java:503) at com.maze.client.MyClient.overviewTest(MyClient.java:34) at com.maze.client.MyClient.main(MyClient.java:64)
我不懂为什么.
这是服务：
@GET
@Produces(MediaType.APPLICATION_JSON )
@Path("/overview")
public JSONArray getOverviewEntities(@QueryParam("countryid")String id){
JSONArray array = null;
try{
Integer countryId = Integer.parseInt(id);
ArrayList<Event> list = new ArrayList<Event>();
EventService event = new EventService();
EntityManagerSingleton.getInstance().getTransaction().begin();
list.addAll(event.getList(countryId,"country",5));
EntityManagerSingleton.getInstance().getTransaction().commit();
for(Event ev : list){
array.add(EventService.toJSONObject(ev));
}
} catch(Exception e){
e.printStackTrace();
}
return array;
}
这是客户：
public static void overviewTest(){
WebResource wbr;
Client client = Client.create();
wbr = client.resource("http://localhost:8080/Maze/rest/service/overview");
JSONArray result = wbr.queryParam("countryid","1").accept(MediaType.APPLICATION_JSON).get(JSONArray.class);
System.out.println(result.toString());
}
我真的不知道问题可能是什么.我知道另一个问题,看似相同的主题,但他们不是.
如果我遗漏了某些内容或者您需要任何额外信息,请告诉我.
