我正在尝试通过 ESB 从 JSON 客户端向 DSS 服务器调用请求,我正在尝试调用获取数据服务,客户端代码、ESB Insequence 配置如下所示。我收到如下所示的服务器错误:
LogMediator To:http ://www.w3.org/2005/08/addressing/anonymous,WSAction:,SOAPAction:,MessageID:urn:uuid:da913ea8-4122-4f58-9732-4106a55b465a,方向:响应,MESSAGE = Executing默认“故障”序列,ERROR_CODE = 0,ERROR_MESSAGE = 发送回消息时发生意外错误,信封:
客户端代码是:
URL url = new URL("http://xxx:xx:xx:xxx/entitytype");
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setDoOutput(true);
conn.setRequestMethod("POST");
conn.setRequestProperty("Content-Type", "application/json");
String studentDetails = "{\"hierarchyEntityRequest\":{\"entityName\":\"Chandragiri\",\"parentEntity\":900000001}}";
System.setProperty("studentDetails",studentDetails);
OutputStream os = conn.getOutputStream();
os.write(studentDetails.getBytes());
os.flush();
if (conn.getResponseCode() != HttpURLConnection.HTTP_CREATED) {
throw new RuntimeException("Failed : HTTP error code : "
+ conn.getResponseCode());
}
BufferedReader br = new BufferedReader(new InputStreamReader(
(conn.getInputStream())));
conn.disconnect();
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
ESB 配置服务是:
