Hibernate在Spring Batch Job中使用完全JavaConfig aproach

Question

我使用JavaConfig完全配置了批处理作业。有困难，主要是因为我在配置上只使用java的材料很少。在弹簧批处理手册中，没有关于如何使用仅使用java的弹簧批完全配置作业的信息。我不知道是不是因为这个配置模型比基于xml的aprouch更新...

现在我在使用此配置类设置hibernate时遇到问题。我有一个xml设置，但我不知道如何引用它或如何为完全“JavaConfig”版本更改这些设置。

我的工作配置类是：

@Configuration
@EnableBatchProcessing
public class CrawlerBatchConfiguration {


    @Autowired
    private StepBuilderFactory steps;

    @Bean
    public Job job(JobBuilderFactory jobs) {
        return jobs.get("myJob").start(flow()).end().build();
    }

    protected Step step0() {
        return steps.get("setupCrawlerStep").tasklet(tasklet()).build();
    }

    private Flow flow() {
        FlowBuilder<Flow> builder = new FlowBuilder<>("flow1");
        builder.start(step0())
                .next(step1())
                .end();
        return builder.build();
    }


    @Bean
    protected Step step1() {
        return steps.get("processProductStep")
                .<TransferObject, Product>chunk(10)
                .reader(reader())
                .processor(processor())
                .writer(writer())
                .build();
    }

    @Bean
    protected Tasklet tasklet() {
        return new StartCrawlerTasklet();
    }


    @Bean
    protected ProductList getProductList() {
        return new ProductList();
    }

    @Bean
    public CrawlerListener listener() {
        CrawlerListener listener = new RibeiraoListener();
        return listener;
    }


    @Bean
    public ItemProcessor<TransferObject, Product> processor() {
        return new ProductProcessor();
    }

    @Bean
    public ItemReader<TransferObject> reader() {
        return new ProductItemReader();
    }

    @Bean
    public ItemWriter<Product> writer() {
        return new HIbernateProductsItemWriter();
    }


    @Bean
    public Crawler crawler() {
        return new RibeiraoCrawler(new UserAgentFactory());
    }

    @Bean
    public ProductBo productBo() {
        return new ProductBoImpl();
    }

    @Bean
    public ProductDao productDao() {
        return new ProductDaoImpl();
    }
}

和hibernate配置文件：
