Wso2 Data Mapper fehlgeschlagen

Question

Wenn ich versuchte, den Data Mapper Mediator zu verwenden, erhalte ich immer einen Fehler. Ich habe versucht, die JSON-Antwort auf XML zu mappen.

Hier ist meine API. Ich benutze nur die omdbapi, um ein Beispiel zu geben.

<?xml version="1.0" encoding="UTF-8"?> 
<api context="/omdbapi" name="omdbapi" xmlns="http://ws.apache.org/ns/synapse"> 
    <resource methods="GET" uri-template="/*"> 
     <inSequence> 
      <send> 
       <endpoint> 
        <address trace="disable" uri="http://www.omdbapi.com/"/> 
       </endpoint> 
      </send> 
     </inSequence> 
     <outSequence> 
      <datamapper config="gov:datamapper/omdbapiConfig.dmc" inputSchema="gov:datamapper/omdbapiConfig_inputSchema.json" inputType="XML" outputSchema="gov:datamapper/omdbapiConfig_outputSchema.json" outputType="XML"/> 
      <respond/> 
     </outSequence> 
     <faultSequence/> 
    </resource> 
</api>

Wenn Sie versuchen, JSON-> XML abzubilden, müssen Sie in der Data Mapper Mediator Konfiguration angeben. Stellen Sie sicher, dass Sie den Eingabetyp als JSON festgelegt haben.

Und es gab beta2 Release auf wso2 esb. Also versuchen Sie es mit Beta2-Packs für esb runtime und tooling. Benutze das neueste Paket und versuche es.
