服务器端J2EE Web服务获取参数的空值 [英] Server side J2EE Webservice gets null values on parameters

问题描述

我是J2ee的新手，我在这里做错了什么?我的参数获取了空值.

I am a newbie at J2ee, What am I doing wrong here ? I am getting null values for my parameters.

HTTP GET URL

HTTP GET URL

http://:8080/mypath?identity = abcd& identityType = 1

http://:8080/mypath?identity=abcd&identityType=1

代码

@GET
@Path("Request")
@Consumes({ MediaType.TEXT_PLAIN })
public Response get(@PathParam("identity") String identity,
        @PathParam("identityType") int identityType) {
    System.out.println("Identity "+identity+" IdentityType "+identityType) ;

返回

Identity null IdentityType 0

Identity null IdentityType 0

客户端Junit代码

    String phoneNumber = new String("abcd");
    ClientConfig config = new DefaultClientConfig();
    Client client = Client.create(config);

    String authenticateService = "http://" + SERVER
            + "/mypath?";

    List<NameValuePair> params = new LinkedList<NameValuePair>();
    params.add(new BasicNameValuePair("identity", phoneNumber));
    params.add(new BasicNameValuePair("identityType", String
            .valueOf(1)));
    String paramString = URLEncodedUtils.format(params, "utf-8");
    authenticateService += paramString;
    URI url = UriBuilder.fromUri(authenticateService).build();
    WebResource service = client.resource(url);

    System.out.println(authenticateService);

    ->Exception Here<- String identityHash = service.type(MediaType.TEXT_PLAIN).get(
            String.class);
    assertNotNull(identityHash);

客户println返回

Client println returns

http://:8080/mypath?identity = abcd& identityType = 1

http://:8080/mypath?identity=abcd&identityType=1

推荐答案

修复后，将PathParam替换为QueryParam

@GET
@Path("Request")
@Consumes({ MediaType.TEXT_PLAIN })
public Response get(@QueryParam("identity") String identity,
        @QueryParam("identityType") int identityType) {
    System.out.println("Identity "+identity+" IdentityType "+identityType) ;
