如果任何块失败，如何中止春季批处理作业

Question

I have a spring batch application which reads the data from master table and moves all the records which are older that 90 days to an archive table.

the application context file is as "

<context:property-placeholder location="classpath:batch.properties" />

<context:component-scan base-package="com.prax.batch" />

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" >
    <property name="url" value="${batch.jdbc.url}"/>
    <property name="driverClassName" value="${batch.jdbc.driver}"/>
    <property name="username" value="${batch.jdbc.user}"/>
    <property name="password" value="${batch.jdbc.password}"/>
</bean>

<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
    <property name="dataSource" ref="dataSource"/>
</bean>

<bean id="jobReposotoryTransactionManager" class="org.springframework.batch.support.transaction.ResourcelessTransactionManager"/>

<bean id="jobLauncher" class="org.springframework.batch.core.launch.support.SimpleJobLauncher">
    <property name="jobRepository" ref="jobRepository"></property>
</bean>

<!-- <jdbc:initialize-database data-source="dataSource">
    <jdbc:script location="${batch.schema.script}" />
</jdbc:initialize-database> -->

<!-- <batch:job-repository id="jobRepository" transaction-manager="jobReposotoryTransactionManager"></batch:job-repository> -->

<bean id="jobRepository" class="org.springframework.batch.core.repository.support.MapJobRepositoryFactoryBean" >
    <property name="transactionManager" ref="jobReposotoryTransactionManager"/>
</bean>

<import resource="classpath:/META-INF/spring/module-context.xml" />



</beans>

and job context file is as

<batch:job id="fqtvArchiveJob">
    <batch:step id="readWriteDeleteStep">
        <batch:tasklet transaction-manager="transactionManager"
            start-limit="10">
            <batch:chunk reader="fqtvreader" writer="fqtvcompositewriter"
                commit-interval="1000" />
        </batch:tasklet>
    </batch:step>
</batch:job>


<bean id="fqtvreader"
    class="org.springframework.batch.item.database.JdbcCursorItemReader">
    <property name="rowMapper" ref="fqtvrowmapper" />
    <property name="dataSource" ref="dataSource" />
    <property name="sql" value="${batch.reader.sql}" />
    <property name="maxRows" value="0"/>
    <property name="fetchSize" value="0" />
</bean>

<bean id="fqtvinsertwriter"
    class="org.springframework.batch.item.database.JdbcBatchItemWriter">
    <property name="assertUpdates" value="true" />
    <property name="dataSource" ref="dataSource" />
    <property name="itemPreparedStatementSetter" ref="fqtvpreparedstatementsetter" />
    <property name="sql" value="${batch.writer.insert.sql}" />
</bean>

<bean id="fqtvdeletewriter"
    class="org.springframework.batch.item.database.JdbcBatchItemWriter">
    <property name="assertUpdates" value="true" />
    <property name="dataSource" ref="dataSource" />
    <property name="itemPreparedStatementSetter" ref="deletestatementsetter" />
    <property name="sql" value="${batch.writer.delete.sql}" />
</bean>

<bean id="fqtvcompositewriter"
    class="org.springframework.batch.item.support.CompositeItemWriter">
    <property name="delegates">
        <list>
            <ref local="fqtvinsertwriter"/>
            <ref local="fqtvdeletewriter"/>
        </list>
    </property>
</bean>

<bean id="fqtvrowmapper" class="com.prax.job.util.FqtvRowMapper"          />

<bean id="fqtvpreparedstatementsetter"
    class="com.prax.job.util.FqtvPreparedStatementSetter" />

<bean id="deletestatementsetter"
    class="com.prax.job.util.FqtvDeleteStatementSetter" />

</beans>

I have the requirement that if archiving of any item fails, the batch should stop and not archive any more record and send the mail notification to the users.

Answer 1

 <batch:job id="fqtvArchiveJob">
  <batch:step id="readWriteDeleteStep">
     <batch:tasklet transaction-manager="transactionManager"
        start-limit="10">
        <batch:chunk reader="fqtvreader" writer="fqtvcompositewriter"
            commit-interval="1000" skip-limit="10" >
        <skippable-exception-classes>
            <exclude class="customExceptionIDontWannaSkip"/>
        </skippable-exception-classes>
       </batch:chunk>
   </batch:tasklet>
 </batch:step>
  <batch:listeners>
                <batch:listener ref="jobListener" />
  </batch:listeners>
</batch:job>

And JobListener should implements JobExecutionListener and override :

@Override
public void afterJob(JobExecution exec) {
  BatchStatus status = exec.getStatus();
  if (!status.equals(BatchStatus.COMPLETED)){
   //send the mail
  }
}
