Transaction Attributes

You can use transaction attributes to control the isolation, propagation, and timeout settings. You can find more information on setting transaction attributes in the Spring core documentation.

Java
XML

The following example sets the isolation, propagation, and timeout transaction attributes in Java:

Java Configuration

@Bean
public Step step1(JobRepository jobRepository, PlatformTransactionManager transactionManager) {
	DefaultTransactionAttribute attribute = new DefaultTransactionAttribute();
	attribute.setPropagationBehavior(Propagation.REQUIRED.value());
	attribute.setIsolationLevel(Isolation.DEFAULT.value());
	attribute.setTimeout(30);
	return new StepBuilder("step1", jobRepository)
				.<String, String>chunk(2, transactionManager)
				.reader(itemReader())
				.writer(itemWriter())
				.transactionAttribute(attribute)
				.build();
}

The following example sets the isolation, propagation, and timeout transaction attributes in XML:

XML Configuration

<step id="step1">
 <tasklet>
 <chunk reader="itemReader" writer="itemWriter" commit-interval="2"/>
 <transaction-attributes isolation="DEFAULT"
 propagation="REQUIRED"
 timeout="30"/>
 </tasklet>
</step>
