Spring Batch jobRepository配置

Question

这是我的配置文件：

@Configuration
@EnableBatchProcessing
@Import(DatasourceConfig.class)

public class BatchProcessConfiguration {

@Autowired
public JobBuilderFactory jobBuilderFactory;

@Autowired
public StepBuilderFactory stepBuilderFactory;

@Autowired
public DriverManagerDataSource dataSource;

@Bean
MapJobRepositoryFactoryBean jobRepository() {
    MapJobRepositoryFactoryBean mjRFBean = new MapJobRepositoryFactoryBean();
    mjRFBean.setTransactionManager(transactionManager());
    return mjRFBean;
}

@Bean
SimpleJobLauncher jobLauncher() throws Exception {
    SimpleJobLauncher jobLauncher = new SimpleJobLauncher();

    JobRepository jobRepo = jobRepository().getJobRepository();


    jobLauncher.setJobRepository(jobRepo);
    return jobLauncher;
}

@Bean
JdbcCursorItemReader<MyDto> databaseItemReader() {
    JdbcCursorItemReader<MyDto> jdbcItemReader = new JdbcCursorItemReader<MyDto>();
    jdbcItemReader.setDataSource(dataSource);
    jdbcItemReader.setSql(QUERY);
    jdbcItemReader.setRowMapper(new ControparteRowMapper());

    return jdbcItemReader;
}

@Bean
FlatFileItemWriter<MyDto> fileItemWriter() {
    ...
}

...

@Bean
MyListener jobListener() {
    return new MyListener();
}

@Bean
MyProcessor itemProcessor() {
    return new MyProcessor();
}

ResourcelessTransactionManager transactionManager() {
    return new ResourcelessTransactionManager();
}

@Bean
public Job myJob(MyJobListener listener) {
    ...
}

@Bean
public Step step1() {
    ...
}

我有这个错误：

    Exception in thread "main" org.springframework.beans.factory.UnsatisfiedDependencyException: 
Error creating bean with name 'batchProcessConfiguration': Unsatisfied dependency expressed through field 'jobBuilderFactory'; 
nested exception is org.springframework.beans.factory.BeanCreationException: 
Error creating bean with name 'jobBuilders' defined in class path resource [org/springframework/batch/core/configuration/annotation/SimpleBatchConfiguration.class]:

org.springframework.batch.core.repository.support.MapJobRepositoryFactoryBean$$EnhancerBySpringCGLIB$$2bfb173 cannot be cast to org.springframework.batch.core.repository.JobRepository

我的配置有什么问题？

感谢。
