Spring Batch Infrastructure defined with Java Config Beans not with @EnableBatchProcessing

I use Spring Batch 4.3.2. I need to define a TaskExecutor for the JobLauncher. As i don't want to enable bean overriding, the solution with DefaultBatchConfigurer is not applicable. I ended up with the the beans below, defining all bean on my own. My Question:

1. Do you see an other solutions than mine?
2. Are the beans defined the correct way?

Thanks for your help! Cheers T

 @Bean
public JobBuilderFactory jobBuilderFactory(JobRepository jobRepository) {
    return new JobBuilderFactory(jobRepository);
}

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

@Bean
public JobRegistry jobRegistry() {
    return new MapJobRegistry();
}

@Bean
public JobRepository createJobRepository(DataSource dataSource, PlatformTransactionManager transactionManager) throws Exception {
    JobRepositoryFactoryBean factory = new JobRepositoryFactoryBean();
    factory.setDataSource(dataSource);
    factory.setTransactionManager(transactionManager);
    factory.afterPropertiesSet();
    return factory.getObject();
}

@Bean
public JobExplorer createJobExplorer(DataSource dataSource) throws Exception {
    JobExplorerFactoryBean jobExplorerFactoryBean = new JobExplorerFactoryBean();
    jobExplorerFactoryBean.setDataSource(dataSource);
    jobExplorerFactoryBean.afterPropertiesSet();
    return jobExplorerFactoryBean.getObject();
}

@Bean
public JobLauncher jobLauncher(ThreadPoolTaskExecutor taskExecutor, JobRepository jobRepository) throws Exception {
    SimpleJobLauncher jobLauncher = new SimpleJobLauncher();
    jobLauncher.setJobRepository(jobRepository);
    jobLauncher.setTaskExecutor(taskExecutor);
    jobLauncher.afterPropertiesSet();
    return jobLauncher;
}

@Bean
public ThreadPoolTaskExecutor msBatchTaskExecutor() {
    ThreadPoolTaskExecutor taskExecutor = new ThreadPoolTaskExecutor();
    taskExecutor.setCorePoolSize(5);
    taskExecutor.setMaxPoolSize(50);
    taskExecutor.setQueueCapacity(50);
    return taskExecutor;
}
