REST Web服務-映射到Java Complex對象的JSON請求

Question

我正在嘗試將JSON映射並發送到Java對象以進行Rest Web Service。 我正在使用帶有Jersey Java的RESTful WS。

我是這個REST的新手，如果發送不正確，請更正我。

**這是My JSON的示例：

Google Rest插件中作為原始數據的MY Json輸入是：** 如下

JSON輸入：我需要將其映射到：com.cordys.entity.bean.ClaimTask ClaimTaskObj

{ “TASKID”：[ “002481F0-8E9F-11E3-FB97-B80661C15631”， “002481F0-8E9F-11E3-FB97-B80661C15635”]}

================================================== ============================== 我遇到了以下錯誤：

因此，每次我發送此請求時，都會出現以下錯誤：

com.sun.jersey.spi.container.ContainerResponse mapMappableContainerException嚴重：無法將MappableContainerException中包含的異常映射到響應，重新拋出到HTTP容器org.codehaus.jackson.map.exc.UnrecognizedPropertyException：無法識別的字段“ taskId ”（com.business.entity.bean.ClaimTask類），未在[來源：org.apache.catalina.connector.CoyoteInputStream@409b5f9c;上標記為可忽略。 行：1，列：12]（通過參考鏈：com.business.entity.bean.ClaimTask [“ taskId”]），位於org.codehaus.jackson.map.exc.UnrecognizedPropertyException.from（UnrecognizedPropertyException.java:53） org.codehaus.jackson上的org.codehaus.jackson.map.deser.std.StdDeserializer.reportUnknownProperty（StdDeserializer.java:673）上的org.codehaus.jackson.map.deser.StdDeserializationContext.unknownFieldException（StdDeserializationContext.java:267）。 org.codehaus.jackson.map.deser.BeanDeserializer.handleUnknownProperty（BeanDeserializer.java:1365）上的map.deser.std.StdDeserializer.handleUnknownProperty（StdDeserializer.java:659）在org.codehaus.jackson.map.deser.BeanDeserializer處。 org.codehaus.jackson.map.deser.BeanDeserializer.deserialize（BeanDeserializer.deserialize（BeanDeserializer.java:580）上的_handleUnknown（BeanDeserializer.java:725）在org.codehaus.jackson.map.deser.BeanDeserializer.deserializeFromObject（BeanDeserializer.java:703）在org.codehaus.jac上的org.codehaus.jackson.map.ObjectMapper._readValue（ObjectMapper.java:2704） org.codehaus.jackson.jaxrs.JacksonJsonProvider.readFrom（JacksonJsonProvider.java:419）處的com.sun.jersey.json.impl.provider.entity.JacksonProviderProxy處的kson.map.ObjectMapper.readValue（ObjectMapper.java:1315）。 com.sun.jersey.spi.container.ContainerRequest.getEntity（ContainerRequest.java:488）處的com.sun.jersey.server.impl.model.method.dispatch.EntityParamDispatchProvider $ EntityInjecta的readFrom（JacksonProviderProxy.java:139）

我的休息服務方法。

@POST
@ApiResponses(value = {
        @ApiResponse(code = 200, message = STATUS_200),
        @ApiResponse(code = 500, message = STATUS_500)
})
@Path("/claimTaskObj")
@Consumes({ "application/json", "application/xml"})
@Produces({ "application/json", "application/javascript", "application/xml" })
public Response claimTaskObj(
        com.business.entity.bean.ClaimTask claimTaskObj,
        @HeaderParam("SAMLart") String samlArt,
        @HeaderParam("otdsticket") String oTAuthenticationHeader,
        @Context UriInfo uriInfo) {
    System.out.println("TaskService.claimTask()====== IN");
    // Integration with JAXWS
    //System.out.println("oTAuthenticationHeader ="+oTAuthenticationHeader);
    ClaimTaskJaxWsClient claimTaskClient = new ClaimTaskJaxWsClient();
    ClaimTaskResponse jaxWSResponse = null;
    MultivaluedMap<String, String> inputParameters = uriInfo.getQueryParameters();
    inputParameters.add("task_id", claimTaskObj.getTaskId().get(0));

    String callback = inputParameters.getFirst("callback");
    try {
        jaxWSResponse = claimTaskClient.executeSoapRequest(inputParameters, samlArt,oTAuthenticationHeader);
        return Util.getRespone(jaxWSResponse, callback, 200);
    } catch (com.business.jaxws.task.claimtask.businessFaultDetail e) {
        return Util.getRespone(e.getFaultInfo(), callback, 500);
    } 

}

您可以通過實現以下代碼來解決和測試您的Web服務

  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();
