Question

I have created a spring-batch job. My reader class reads the data from the DB and gives back the dataset object having the below structure.

@XmlRootElement
@XmlType(propOrder = { "start", "end", "users"})
public class DataSet implements Serializable {

    /**
     * Start datetime of this data set
     */
    private Date start;

    /**
     * End datetime of this data set
     */
    private Date end;

    /**
     * Providers involved in this data set
     */
    private List<User> users;
}

etc…… and the writer wites the above data using StaxEventItemWriter.
The resulting xml contains two root tag elements.

<root>  //added by the startDocument and endDocument methods from stax writer. 
  <DataSet>......</DataSet>  // from the dataSet xsd annotation.
</root>

i need to eliminate the with out overriding the startDocument and endDocument methods.

is there a way to do it through the configuration. its urgent please.

my writer configuartion is given below.

<bean id="testrWriter" class="com.test.writer.TestWriter"
        scope="step">
<property name="testXMLWriter" ref="testXMLWriter" />
<property name="baseDirectory" value"#{jobParameters['baseDirectory']}"></property>
</bean>

<bean id="testXMLWriter" class="org.springframework.batch.item.xml.StaxEventItemWriter">
   <property name="overwriteOutput" value="true" /> 
   <property name="marshaller" ref="testJaxb2Marshaller" /> 
</bean>

<bean id="testJaxb2Marshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshaller">
    <property name="classesToBeBound">
    <list>
             <value>com.test.service.dto.DataSet</value>
    </list>
   </property> 
</bean

Answer 1

I set the root to !-- --

finally got a valid xml.

<bean id="delegateWriter" class="org.springframework.batch.item.xml.StaxEventItemWriter">
    <property name="marshaller" ref="someMarshaller" />
    <property name="overwriteOutput" value="true" />
    <property name="RootTagName" value="!-- --"/>
</bean>
