Problems Restart with CompositeItemWriter

[xgiangi]

We have a problem with CompositeItemWriter. In particular, we can not handle restart.
Following an error, the table is stored BATCH_STEP_EXECUTION_CONTEXT only the outcome of writing the second file itemWriterFile2
(in the field SHORT_CONTEXT is enhanced with {"map":{"entry":[{"string":"FlatFileItemReader.read.count","int":37 },{"string":"FlatFileItemWriter.written","long":2} ,{"string":"FlatFileItemWriter.current.count","lon g":98}]}})

The outcome of writing the first file is stored where itemWriterFile1?

The configuration of the job is as follows:

<b:job id="loaderJob" job-repository="jobRepository" restartable="true">
<b:step id="loaderStep">
<b:tasklet transaction-manager="batchTransactionManager">
<b:chunk reader="loaderReader" processor="loaderProcessor" writer="itemWriterComposite" commit-interval="1">
<b:streams>
<b:stream ref="fileItemReader"/>
<b:stream ref="itemWriterFile1"/>
<b:stream ref="itemWriterFile2"/>
</ b:streams>
</ b:chunk>
</ b:tasklet>
</ b:step>
</ b:job>

<bean id="itemWriterComposite" class="org.springframework.batch.item.support.CompositeItemWriter">
<property name="delegates">
<list>
<ref bean="itemWriterFile1" />
<ref bean="itemWriterFile2" />
</list>
</property>
</bean>

<bean id="itemWriterFile1" class="com.write.ItemFile1" >
		<property name="delegate">
			<bean class="org.springframework.batch.item.file.FlatFileItemWriter">
				 <property name="resource" value="file:target/test-outputs/output1.txt" />
				 
				<property name="lineAggregator">
					<bean class="org.springframework.batch.item.file.transform.PassThroughLineAggregator" />
				</property>
			</bean>
		</property>		
	</bean>
	
	<bean id="itemWriterFile2" class="com.write.ItemFile2" >
		<property name="delegate">
			<bean class="org.springframework.batch.item.file.FlatFileItemWriter">
				 <property name="resource" value="file:target/test-outputs/output2.txt" />
				 
				<property name="lineAggregator">
					<bean class="org.springframework.batch.item.file.transform.PassThroughLineAggregator" />
				</property>
			</bean>
		</property>		
	</bean>

FlatFileItemWriter (and similar components) has a naming convention for the ExecutionContext keys. You need to override it if yo have two in the same step using the "name" property.
