Beim Versuch, eine Kunden-> Bestellung 1: n-Beziehung mit Jaxb 2.2.6 zuordnen Ich möchte die Liste der Aufträge in einem separaten Knoten "Aufträge" verpackt bekommen.So wickeln Sie die Unterliste mit Jaxb
derzeit das Ergebnis:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Customer>
<id>100</id>
<name>John Doe</name>
<orders>
<address>100 main street, smalltown, pa</address>
<orderid>1100</orderid>
</orders>
<orders>
<address>5 broadway, ny, ny</address>
<orderid>1200</orderid>
</orders>
</Customer>
aber ich möchte bekommen:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Customer>
<id>100</id>
<name>John Doe</name>
<orders>
<order>
<address>100 main street, smalltown, pa</address>
<orderid>1100</orderid>
</order>
<order>
<address>5 broadway, ny, ny</address>
<orderid>1200</orderid>
</order>
</orders>
</Customer>
Was muss geändert werden, dieses Ergebnis zu bekommen?
Der entsprechende Quellcode hat:
- Kundenschnittstelle
- CustomerJaxbDao Implementierung
- Bestellen Schnittstelle
- OrderJaxbDao Implementierung
- TestCustomerWrite junit4 Testfall
