Spring Batch 3.0.2 integration with Spring Core 4.1.x - What is the appropriate way to use @EnableBatchProcessing?

Question

I'm trying to run Spring Batch Admin app with Spring Boot and it looks like that I have the same issue. Preferred solution would be to use Java configuration, instead of XML.

What would be appropriate solution to use @EnableBatchProcessing with Spring Batch Admin?

I had a look on this question, but I wasn't able to solve the issue.

Thank you in advance.

Spring Batch configuration:

@Configuration
@EnableBatchProcessing
@ImportResource({
        "classpath:org/springframework/batch/admin/web/resources/servlet-config.xml",
        "classpath:org/springframework/batch/admin/web/resources/webapp-config.xml"
    })
public class BatchConfig {
}

Spring Boot starter implementation:

@Configuration
@EnableAutoConfiguration(exclude = { BatchAutoConfiguration.class, DataSourceAutoConfiguration.class, WebMvcAutoConfiguration.class })
@Import(BatchConfiguration.class)
public class Application extends SpringBootServletInitializer {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return super.configure(application);
    }
}

Answer 1

Working example (@EnableBatchProcessing is removed, JobBuilderFactory and StepBuilderFactory are created in Java configuration):

@Configuration
@ImportResource(
        value = {
                "classpath:org/springframework/batch/admin/web/resources/servlet-config.xml",
                "classpath:org/springframework/batch/admin/web/resources/webapp-config.xml"
        }
    )
public class BatchConfiguration {
    @Bean
    public JobBuilderFactory jobBuilderFactory(JobRepository jobRepository) {
        return new JobBuilderFactory(jobRepository);
    }

    @Bean
    public StepBuilderFactory stepBuilderFactory(JobRepository jobRepository, PlatformTransactionManager transactionManager) {
        return new StepBuilderFactory(jobRepository, transactionManager);
    }
}

Answer 2

The error you are getting is because @EnableBatchProcessing registers a StepScope and so does Spring Batch Admin. As I mentioned in the post you referenced, I would not recommend using @EnableBatchProcessing with Spring Batch Admin and instead, just configure the beans you need (only the job factory and step factory).
