Unable to write expected XML file with StaxEventItemWriter
Hi all,
I am trying to process the following XML to add and set some properties to items:
HTML Code:
<lot xmlns:xsi=...>
<id>...</id>
<date>...</date>
<desc>...</desc>
<items>
<item>...</item>
<item>...</item>
....
<item>...</item>
</items>
</lot>
. I use StexEventItemReader abd Jaxb2 unmarshaller for unmarshalling : all works fine.
. I modify my Jaxb2 objects as expected
. At marshalling step is my problem:
I use StaxEventItemWriter and Jaxb2 marshaller, but i am not able to well reconstitute
the XML file. What i obtain is something like:
HTML Code:
<lot>
<lot>
<id>...</id>
<date>...</date>
<desc>...</desc>
<items>
<item>...</item>
<item>...</item>
....
<item>...</item>
</items>
</lot>
</lot>
as we can see: the root tag element is put twice for opening and closing the xml document.
My configuration is like this:
Code:
<beans:bean id="myWriter" class="com.MyWriter">
<beans:property name="delegate" ref="xmlWriter" />
</beans:bean>
<beans:bean id="xmlWriter" class="org.springframework.batch.item.xml.StaxEventItemWriter">
<beans:property name="rootTagName" value="lot" />
<beans:property name="marshaller" ref="marshaller" />
<beans:property name="overwriteOutput" value="true" />
<beans:property name="resource" ref="fichierOUT" />
</beans:bean>
<beans:bean id="marshaller"
class="org.springframework.oxm.jaxb.Jaxb2Marshaller">
<beans:property name="classesToBeBound">
<beans:list>
<beans:value>Lot</beans:value>
<beans:value>Items</beans:value>
<beans:value>Item</beans:value>
</beans:list>
</beans:property>
<beans:property name="schema" value="file:./myXSD.xsd"/>
</beans:bean>
In the class MyWriter, in the 'write' method, the delegate writer (StaxEventItemWriter) writes the object transmitted in parameter (here a 'Lot' object):
Code:
delegate.write(lot)
I tried to make the delegate write only the 'items' block, but in this case i lose the other information of the lot (see the following xml):
HTML Code:
<lot>
<items>
<item>...</item>
<item>...</item>
....
<item>...</item>
</items>
</lot>
What is wrong in my configuration? how is it possible to obtain the XML expected? If you have a sample of code doing that, it would be great!
Thanks in advance ofr your help on this!
