Wie referenziere ich einen JAXB POJO in einem Mule-Fluss

Question

Ich habe erfolgreich ein XML Dokument in ein JAXB Objekt entmarshaliert, aber jetzt möchte ich auf das Objekt im Fluss verweisen und den Wert seiner Eigenschaften in eine Datenbanktabelle einfügen.

Die Strömung ist wie folgt:

<?xml version="1.0" encoding="UTF-8"?> 
<mule xmlns:http="http://www.mulesoft.org/schema/mule/http" xmlns:mulexml="http://www.mulesoft.org/schema/mule/xml" xmlns="http://www.mulesoft.org/schema/mule/core" xmlns:doc="http://www.mulesoft.org/schema/mule/documentation" xmlns:spring="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans   http://www.springframework.org/schema/beans/spring-beans-current.xsd

<http:listener-config name="HTTP_Listener_Configuration" host="0.0.0.0" port="10009" basePath="/ipay/bra" doc:name="HTTP Listener Configuration"/> 
<mulexml:jaxb-context name="JAXB_Context" packageNames="com.dhg.api" doc:name="JAXB Context"/> 
<flow name="transaction_initiation_testFlow"> 
    <http:listener config-ref="HTTP_Listener_Configuration" path="/transaction" doc:name="HTTP"> 
     <http:response-builder> 
      <http:header headerName="Content-Type" value="text/xml"/> 
     </http:response-builder> 
    </http:listener> 
    <mulexml:jaxb-xml-to-object-transformer returnClass="com.dhg.api.PAYMENTS" jaxbContext-ref="JAXB_Context" doc:name="XML to JAXB Object"/> 
    <logger message="#[payload.transaction.email]" level="INFO" doc:name="Logger"/> 
    <echo-component doc:name="Echo"/> 
</flow> 
</mule> 

Das Objekt ist wie folgt:

        } 

       } 

      } 

     } 

    } 

} 

} 

Nach unmarshalling, wird das Objekt als com.dhg.api.PAYMENTS@some_random_string instanziiert, die sie an Referenz erschwert. Also meine Frage ist einfach, wie kann ich auf dieses Objekt verweisen und in der Lage sein, auf die Werte zuzugreifen, die anderswo im Fluss verwendet werden.

Danke für Ihre Hilfe.

Answer 1

Ihre Setter/Getter ist nicht kompatibel mit Eigenschaftsnamen in:

public PAYMENTS.TRANSACTION getTRANSACTION() { 
    return transaction; 
} 

public void setTRANSACTION(PAYMENTS.TRANSACTION value) { 
    this.transaction = value; 
} 

So in <logger message="#[payload.transaction.email]" level="INFO" doc:name="Logger"/> der transaction Teil ist null.

Der korrekte Getter-Name ist getTransaction und ist derselbe für Setter. Ändern sie bitte
