Question

我写了一个REST网络服务，用于接受来自客户端的json数组，但我得到了java.lang.IndexOutOfBoundsException

任何人都可以告诉我一些解决方案吗

客户端

public class Test {
    public static void main(String[] args) {
        try{
        ClientConfig config = new DefaultClientConfig();
        Client client = Client.create(config);
        client.addFilter(new LoggingFilter());
        HashMap dados=new HashMap();
        WebResource service = client.resource("http://localhost:8224/SampleREST/REST/WebService/MyReceive");
        JSONObject data= new JSONObject();
        dados.put("Name", "John");
        dados.put("Age", "30");
        dados.put("City", "Tokyo");
        data.accumulate("ss", dados);
        ClientResponse client_response = service.accept(MediaType.APPLICATION_JSON).post(ClientResponse.class, data);

        System.out.println("Status: "+client_response.getStatus());

        client.destroy();
        }catch(Exception s){s.printStackTrace();}
    }

}

服务器

 @POST
        @Path("/MyReceive")

        @Consumes(MediaType.APPLICATION_JSON)
        @Produces(MediaType.APPLICATION_JSON)

        //Receive and send a json object
        public JSONObject receiveJSONObject(JSONObject json) throws JSONException
        {
            System.out.println(json.toString());
               return json;
        }

异常

您需要使用@FormParam来使用POST正文。尝试更改此内容：

    public JSONObject receiveJSONObject(JSONObject json) throws JSONException

到

    public JSONObject receiveJSONObject(@FormParam("") JSONObject json) throws JSONException

将JSON发送到REST Web服务 - java.lang.IndexOutOfBoundsException
