我的RESTful客户端有这个方法:
public void testGetCateogrywiseData() {
ClientConfig config = new DefaultClientConfig();
Client client = Client.create(config);
client.addFilter(new LoggingFilter(System.out));
WebResource service = client
.resource("http://localhost:8080/MyApp/rest/publicdata");
@SuppressWarnings("rawtypes")
MultivaluedMap queryParams = new MultivaluedMapImpl();
queryParams.add("latitude", "18.522387");
queryParams.add("longitude", "73.878437");
queryParams.add("categoryID", "2");
service.queryParams(queryParams);
ClientResponse response = service.get(ClientResponse.class);
System.out.println(response.getStatus());
System.out.println("Form response " + response.getEntity(String.class));
}
在服务器端,方法如下所示:
@Path("publicdata")
@GET
@Produces(MediaType.TEXT_HTML)
@Consumes(MediaType.APPLICATION_FORM_URLENCODED)
public String getPublicData() throws JSONException {
MultivaluedMap<String, String> valueMap = uriInfo.getQueryParameters();
Long latString = Long.parseLong(valueMap.getFirst("latitude"));
Long lonString = Long.parseLong(valueMap.getFirst("longitude"));
Long categoryId = Long.parseLong(valueMap.getFirst("categoryID"));
// Do necessary stuff and return json string
return null;
}
我的问题是服务器端的valueMap始终为空。它永远不会得到我从客户端代码发送的三个参数。我错过了什么?

问题出现在这一行:
service.queryParams(queryParams);
它成功添加了查询参数,但它不会更改原始service
,它会向您返回一个新参数。为了使其工作,您需要更改为:
service = service.queryParams(queryParams);
