是您可以传递包装器对象(类的对象)。

添加依赖:

         <!-- jersey -->
    <dependency>
        <groupId>com.sun.jersey</groupId>
        <artifactId>jersey-json</artifactId>
        <version>1.8</version>
    </dependency>
   <dependency>
        <groupId>com.sun.jersey</groupId>
        <artifactId>jersey-server</artifactId>
        <version>1.8</version>
    </dependency>

<dependency>
    <groupId>com.sun.jersey</groupId>
    <artifactId>jersey-client</artifactId>
    <version>1.8</version>
</dependency>

    <dependency>
    <groupId>org.json</groupId>
    <artifactId>json</artifactId>
    <version>20090211</version>
</dependency>

ForGetMethod并传递两个参数:

          Client client = Client.create();
           WebResource webResource1 = client
                        .resource("http://localhost:10102/NewsTickerServices/AddGroup/"
                                + userN + "/" + groupName);

                ClientResponse response1 = webResource1.get(ClientResponse.class);
                System.out.println("responser is" + response1);

GetMethod传递一个参数并获得List的响应:

       Client client = Client.create();

        WebResource webResource1 = client
                    .resource("http://localhost:10102/NewsTickerServices/GetAssignedUser/"+grpName);    
    //value changed
    String response1 = webResource1.type(MediaType.APPLICATION_JSON).get(String.class);

    List <String > Assignedlist =new ArrayList<String>();
     JSONArray jsonArr2 =new JSONArray(response1);
    for (int i =0;i<jsonArr2.length();i++){

        Assignedlist.add(jsonArr2.getString(i));    
    }

In Above It返回一个List,我们接受它作为List,然后将其转换为Json Array,然后将Json Array转换为List。

如果Post Request将Json Object作为参数传递:

   Client client = Client.create();
    WebResource webResource = client
            .resource("http://localhost:10102/NewsTickerServices/CreateJUser");
    // value added

    ClientResponse response = webResource.type(MediaType.APPLICATION_JSON).post(ClientResponse.class,mapper.writeValueAsString(user));

    if (response.getStatus() == 500) {

        context.addMessage(null, new FacesMessage("User already exist "));
    }

此处用户是用户类的对象。在post参数中进行的操作。
