java - REST Web 服务 - JSON 请求映射到 java Complex 对象

Question

我正在尝试将 JSON 映射并发送到用于 Rest Web 服务的 Java 对象。我正在使用带有 Jersey Java 的 RESTful WS。

我是此 REST 的新手，如果发送不正确，请纠正我。

** 这是我的 JSON 的示例:

Google Rest 插件中我的 Json 输入作为原始数据是:** 如下

JSON 输入: 我需要将其映射到: com.cordys.entity.bean.ClaimTask ClaimTaskObj

{"taskId":["002481F0-8E9F-11E3-FB97-B80661C15631","002481F0-8E9F-11E3-FB97-B80661C15635"]}

================================================== =================================== 我遇到以下错误:

因此每次我发送此请求时都会出现以下错误:

您可以通过实现以下代码来解决和测试您的网络服务

  ClaimTask claim = new com.howtodoinjava.model.ClaimTask();
  claim.setTaskId("002481F0-8E9F-11E3-FB97-B80661C15631");
  claim.setTaskId("002481F0-8E9F-11E3-FB97-B80661C15635");

  StringWriter writer = new StringWriter();
  JAXBContext jaxbContext = JAXBContext.newInstance(ClaimTask.class);
  Marshaller jaxbMarshaller = jaxbContext.createMarshaller();
  jaxbMarshaller.marshal(claim, writer);

 DefaultHttpClient httpClient = new DefaultHttpClient();

 // Define a postRequest request
 HttpPost postRequest = new HttpPost(
"http://localhost:8090/BPMService/v1/tasks/claimTaskObj");

 // Set the API media type in http content-type header
 postRequest.addHeader("SAMLart","XXXXXX");
 postRequest.addHeader("otdsticket","YYYYYYYYYYYYY");
 postRequest.addHeader("content-type", "application/xml");

// Set the request post body
StringEntity userEntity = new StringEntity(writer.getBuffer().toString());
postRequest.setEntity(userEntity);

// Send the request; It will immediately return the response in
// HttpResponse object if any
HttpResponse response = httpClient.execute(postRequest);

// verify the valid error code first
int statusCode = response.getStatusLine().getStatusCode();
