我想升级到Hibernate 5,但由于一些奇怪的原因我无法让它工作.

我的Hibernate 4的Spring上下文配置如下所示:

....
<bean id="sessionFactory"
    class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="annotatedClasses" ref="hibernateClasses" />
    <property name="hibernateProperties">
        <props>
            <prop key="hibernate.dialect">
                ${hibernate.dialect}
            </prop>
            <prop key="hibernate.show_sql">
                ${hibernate.show_sql}
            </prop>
            <prop key="hibernate.format_sql">true</prop>
            <prop key="hibernate.generate_statistics">
                ${hibernate.generate_statistics}
            </prop>
            <prop key="hibernate.hbm2ddl.auto">
                ${hibernate.hbm2ddl.auto}
            </prop>
        </props>
    </property>
</bean>

<bean id="transactionManager"
    class="org.springframework.orm.hibernate4.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory" />
</bean>

....

我遗漏了数据源和hibernateClasses bean定义.

对于Hibernate 5,我将包名改为hibernate5,如下所示:

....
<bean id="sessionFactory"
    class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="annotatedClasses" ref="hibernateClasses" />
    <property name="hibernateProperties">
        <props>
            <prop key="hibernate.dialect">
                ${hibernate.dialect}
            </prop>
            <prop key="hibernate.show_sql">
                ${hibernate.show_sql}
            </prop>
            <prop key="hibernate.format_sql">true</prop>
            <prop key="hibernate.generate_statistics"> …

根据Spring Batch文档,开箱即用的重新启动作业,但我无法从它离开的位置开始.例如,如果我的步骤处理了10个记录,它应该从记录11开始,每当我重新启动它时进行处理 在实践中,这不会发生.它从beginnen中读取并重新处理所有内容.

是否有人使用基于Java配置的简单作业配置来读取分隔文件并将内容写入可以从停止点重新启动的db表？

@Configuration
public class BatchConfiguration {

    @Value("${spring-batch.databaseType}")
    private String databaseType;

    @Value("${spring-batch.databaseSchema}")
    private String schemaName;

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

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

    @Bean
    public JobRepository jobRepository(final DataSource dataSource, final PlatformTransactionManager transactionManager) {

        final JobRepositoryFactoryBean bean = new JobRepositoryFactoryBean();
        bean.setDatabaseType(databaseType);
        bean.setDataSource(dataSource);
        if (StringUtils.isNotBlank(schemaName)) {
            bean.setTablePrefix(schemaName);
        }
        bean.setTransactionManager(transactionManager);
        try {
            bean.afterPropertiesSet();
            return bean.getObject();
        } catch (final Exception e) {
            throw new …

由于某些原因，我无法从Apache POI获得PdfConverter来在Linux机器上正确转换MS Word文档。在Windows和MacOS上似乎可以正常工作，但是每当我在Linux机器上尝试时，它基本上都不会转换UTF-8字符。我还尝试配置fontEncoding选项，该选项可以传递给PdfConverter，但这似乎无济于事。

final InputStream in = new FileInputStream(new File("src/test/resources/SOMEDOC.docx"));
final XWPFDocument document = new XWPFDocument(in);
final OutputStream out = new FileOutputStream(new File("target/test.pdf"));
final PdfOptions options = PdfOptions.getDefault();
// This actually breaks the whole conversion. No text will be displayed if you set this font encoding option to UTF-8
options.fontEncoding("UTF-8");
PdfConverter.getInstance().convert(document, out, options);

有人知道我在这里做错了吗？
