Spring Batch Multiple DataSource Session / Entitymanager已关闭

我试图使用Spring Boot和Sprin Batch（JpaPagingItemReader和JpaItemWriter）从SQLServer数据库中将记录拉到Mysql中 . 我已经配置了多个数据源 . 我怎么面对以下错误 .

org.springframework.batch.item.ItemStreamException: Error while closing item reader

以下是我的批处理，步骤配置

@Autowired
private StepBuilderFactory stepBuilderFactory;

@Autowired
@Qualifier("mysqlEntityManager")
private LocalContainerEntityManagerFactoryBean mysqlLocalContainerEntityManagerFactoryBean;

@Autowired
@Qualifier("secondarySqlEntityManager")
private LocalContainerEntityManagerFactoryBean localContainerEntityManagerFactoryBean;

@Autowired
@Qualifier("mysqlTransactionManager")
private PlatformTransactionManager mySqlplatformTransactionManager;


@Autowired
@Qualifier("secondaryTransactionManager")
private PlatformTransactionManager secondaryTransactionManager;


@Autowired
private JobBuilderFactory jobBuilderFactory;

@Bean
public JpaPagingItemReader itemReader(PlatformTransactionManager secondaryTransactionManager) {
    JpaPagingItemReader<SqlServerJobLogs> serverJobLogsJpaPagingItemReader = new JpaPagingItemReader<>();
    serverJobLogsJpaPagingItemReader.setMaxItemCount(1000);
    serverJobLogsJpaPagingItemReader.setPageSize(100);
    serverJobLogsJpaPagingItemReader.setEntityManagerFactory(localContainerEntityManagerFactoryBean.getNativeEntityManagerFactory());
    serverJobLogsJpaPagingItemReader.setQueryString("select p from SqlServerJobLogs p");
    return serverJobLogsJpaPagingItemReader;
}

@Bean
public ItemProcessor itemProcessor() {
    return new DataItemProcessor();
}

@Bean
public ItemWriter itemWriter(PlatformTransactionManager mySqlplatformTransactionManager) {
    DataWriter dataWriter = new DataWriter();
    return dataWriter;
}

@Bean
public Step step() {
    return stepBuilderFactory.get("myJob").chunk(100).reader(itemReader(secondaryTransactionManager)).processor(itemProcessor()).writer(itemWriter(mySqlplatformTransactionManager)).build();
}

@Bean(name = "myJob")
public Job myJob() throws Exception {
    return jobBuilderFactory.get("myJob").start(step()).build();
}

@Bean
public ResourcelessTransactionManager resourcelessTransactionManager(){
    return new ResourcelessTransactionManager();
}

@Bean
public JobRepository jobRepository() throws Exception{
    MapJobRepositoryFactoryBean mapJobRepositoryFactoryBean = new MapJobRepositoryFactoryBean(resourcelessTransactionManager());
    return  mapJobRepositoryFactoryBean.getObject();
}
@Bean
public SimpleJobLauncher jobLauncher() throws Exception {
    SimpleJobLauncher simpleJobLauncher = new SimpleJobLauncher();
    simpleJobLauncher.setJobRepository(jobRepository());
    return simpleJobLauncher;
}

我试图配置BatchConfigurer.But没有运气 . 如果我需要配置除上述细节之外的任何其他内容，请告诉我
