Skippable exception classes for Spring Batch with java based configuration

Question

I configure a step in XML like this:

<batch:step id="slaveStep">
        <batch:tasklet>
            <batch:chunk
                    reader="reader"
                    processor="processor"
                    writer="writer"
                    commit-interval="10"
                    skip-limit="100000">
                <batch:skippable-exception-classes>
                    <batch:include class="MyException"/>
                </batch:skippable-exception-classes>
            </batch:chunk>
        </batch:tasklet>
    </batch:step>

In the java configuration I use a StepBuilder like this:

@Bean
public StepBuilder stepBuilder(String stepName)
{
    return new StepBuilder(stepName);
}

@Bean
Step slaveStep()
{
    return stepBuilder("slaveStep")
            .<Movie, Movie>chunk(10)
            .reader(reader(new HashMap<>()))
            .processor(processor())
            .writer(writer())
            .build();
}

But I could not find a way to configure the skippable exception classes

You need to build up a FaultTolerantStepBuilder using StepBuilder.faultTolerant method.

return stepBuilder()
  .chunk()
  .faultTolerant()
  .skip(MyException.class)
  .skipLimit(100000)
.build()

Thanks for this. Could you point me to where is that information listed? I've searched for it in spring docs and couldn't find any mention of it. – Cristiano Fontes Aug 03 '15 at 16:05

see at http://docs.spring.io/spring-batch/trunk/apidocs/org/springframework/batch/core/step/builder/StepBuilder.html#chunk-org.springframework.batch.repeat.CompletionPolicy- and http://docs.spring.io/spring-batch/trunk/apidocs/org/springframework/batch/core/step/builder/SimpleStepBuilder.html#faultTolerant--. But honestly I found this method while I was looking at SB code – Luca Basso Ricci Aug 03 '15 at 19:45

@Configuration
@EnableBatchProcessing
@Import(DataConfig.class)
    public class SpringBatchConfig {
    ..................
    ..................
    @Autowired
    private StepBuilderFactory stepBuilders;

    @Bean
    public Step loadSlaveStep()
        return stepBuilders.get("slaveStep")()
       .chunk()
       .faultTolerant()
       .skip(MyException.class)
       .skipLimit(100000)
       .build() 
}
