Question

我试图通过ESB从JSON客户端调用请求到DSS服务器，我正在尝试调用获取数据服务，下面给出了客户端代码，ESB顺序配置。我收到服务器错误，如下所示：

LogMediator To：http://www.w3.org/2005/08/addressing/anonymous，WSAction：，SOAPAction：，MessageID：urn：uuid：da913ea8-4122-4f58-9732-4106a55b465a，Direction：response，MESSAGE =执行默认的'fault'序列，ERROR_CODE = 0 ，ERROR_MESSAGE =发回消息时出现意外错误，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：

           <payloadFactory>
  <format>
     <p:getEntityById xmlns:p="http://com.pcs.entity">
           <xs:data xmlns:xs="http://com.pcs.entity">get-property('uri.var.myhierachy')</xs:data>
        </p:getEntityById>
     </format>
     <args>
        <arg xmlns:ns="http://org.apache.synapse/xsd" expression="get-property('uri.var.myhierachy')"/>
     </args>
  </payloadFactory>
  <enrich>
     <source clone="true" type="body"/>
     <target action="replace" type="property" property="myhierachy"/>
  </enrich>
<enrich>
     <source clone="true" type="body"/>
     <target action="replace" type="property" property="myhierachy"/>
  </enrich>
  <send>
     <endpoint key="HierarchyService"/>
  </send>
  <property name="messageType" value="application/json" scope="axis2" type="STRING"/>
  <log level="full" category="TRACE"/>

Answer 1

如果要将消息发送到DSS服务器而不回复，则可以将“OUT_ONLY”属性指定为“true”，如下所述。

<property action="set" name="OUT_ONLY" value="true"/>

如果您希望将回复发送回客户，您可以将介体作为配置的最后一个元素或在序列中包含。

<send/>
