我有一个 json 字符串，它是：

我尝试通过httpclient调用采用上述参数的方法。当我调用如下方法时：

uri = "http://localhost:8080/api/trade/createrequisition";
HttpPost postURI = new HttpPost(uri);
            postURI.setHeader("Content-type", "application/json");
            // Setup the request parameters
            BasicHttpParams params = new BasicHttpParams();
            params.setParameter("CreateRequisitionRO", jsonROConverter.serialiseRequisionRO(request));
            params.setBooleanParameter("validateOnly", validateOnly);
            postURI.setParams(params);

            HttpResponse responseURL = client.execute(postURI);

这就是所谓的方法的签名：

public @ResponseBody
    void createRequisition(@RequestBody CreateRequisitionRO[] request,
            @RequestHeader("validateOnly") boolean validateOnly) {....}

这是我得到的例外：

java.io.EOFException: No content to map to Object due to end of input

可能是什么问题呢。

请帮我解决这个问题。

StringRequestEntity requestEntity = new StringRequestEntity(
    JSON_STRING,
    "application/json",
    "UTF-8");

PostMethod postMethod = new PostMethod("http://localhost:8080/api/trade/createrequisition");
postMethod.setRequestEntity(requestEntity);

int statusCode = httpClient.executeMethod(postMethod);
