我正在使用 Apache HTTP 客户端进行 HTTPPost 调用,然后尝试使用 Jackson 从响应中创建一个对象。这是我的代码:
private static final Logger log = Logger.getLogger(ReportingAPICall.class);
ObjectMapper mapper = new ObjectMapper();
public void makePublisherApiCall(String jsonRequest)
{
String url = ReaderUtility.readPropertyFile().getProperty("hosturl");
DefaultHttpClient client = new DefaultHttpClient();
try {
HttpPost postRequest = new HttpPost(url);
StringEntity entity = new StringEntity(jsonRequest);
postRequest.addHeader("content-type", "application/json");
log.info("pub id :"+ExcelReader.publisherId);
postRequest.addHeader("accountId", ExcelReader.publisherId);
postRequest.setEntity(entity);
HttpResponse postResponse = client.execute(postRequest);
log.info(EntityUtils.toString(postResponse.getEntity()));
// Response<PublisherReportResponse> response = mapper.readValue(postResponse.getEntity().getContent(), Response.class);
// log.info("Reponse "+response.toString());
} catch (UnsupportedEncodingException ex) {
log.error(ex.getMessage());
log.error(ex);
Assert.assertTrue(false, "Exception : UnsupportedEncodingException");
} catch (ClientProtocolException ex) {
log.error(ex.getMessage());
log.error(ex);
Assert.assertTrue(false, "Exception : ClientProtocolException");
} catch (IOException ex) {
log.error(ex.getMessage());
log.error(ex);
Assert.assertTrue(false, "Exception : IOException");
}
方法 makePublisherApiCall() 将在一个循环中调用,该循环运行 100 次。当我取消注释该行时,基本上会出现问题:
// Response<PublisherReportResponse> response = mapper.readValue(postResponse.getEntity().getContent(), Response.class);
// log.info("Reponse "+response.toString());
取消注释后我得到异常:
Attempted read from closed stream.
17:26:59,384 ERROR com.inmobi.reporting.automation.reportingmanager.ReportingAPICall - java.io.IOException: Attempted read from closed stream.
否则它工作正常。有人可以让我知道我做错了什么。
