ich habe in EI_HOME/conf/axis2.xml hinzugefügt

<messageFormatter contentType="application/fhir+json" class="org.wso2.carbon.integrator.core.json.JsonStreamFormatter"/> 

und

<messageBuilder contentType="application/fhir+json" class="org.wso2.carbon.integrator.core.json.JsonStreamBuilder"/> 

aber ohne Erfolg.

Ohne hinzufügen messageBuilder und messageFormatter für "application/Fhir + json" Ich habe den Fehler folgt:

[2017-05-11 11:29:18,247] [] DEBUG - TransportUtils Could not find a Builder for type (application/fhir+json). Using SOAP. 
[2017-05-11 11:29:18,257] [] INFO - BuilderUtil OMException in getSOAPBuilder

     at org.apache.axiom.om.impl.builder.StAXOMBuilder.next(StAXOMBuilder.java:296)... 

Answer 1

Können Sie mit folgenden Herstellern und Formatierer versuchen?

<messageFormatter contentType="application/fhir+json" class="org.apache.synapse.commons.json.JsonStreamFormatter"/> 
<messageBuilder contentType="application/fhir+json" class="org.apache.synapse.commons.json.JsonStreamBuilder"/>
