Hibernate 不更新数据库（尽管它提交并读取它）答案

【问题标题】：Hibernate not updating database (despite it commits and reads it)Hibernate 不更新数据库（尽管它提交并读取它）
【发布时间】：2020-06-20 03:47:46
【问题描述】：

我没有例外，一切似乎都很好，但是在将一些数据插入数据库后，它并没有持久化。我不知道我是否需要一些特定的注释，或者我在某些 Spring 配置中失败了。

实体 bean：

@Entity
@Table(name="IMAGEN")
public class Imagen {

    @Id
    @Column(name="ID")
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Integer id;

    @Column(name="NOMBRE",
            nullable = false)
    private String nombre;

    @Column(name="CATEGORIA",
            nullable = false)
    private String categoria;

    //Getters and setters...

表的 SQL 脚本：

CREATE TABLE IMAGEN(
ID INTEGER IDENTITY PRIMARY KEY,
NOMBRE VARCHAR(64) NOT NULL,
CATEGORIA VARCHAR(32)
);

Imagen 存储库：

@Repository
public interface RepositorioImagen extends JpaRepository<Imagen,Integer> {}

图像服务：

@Service
public class ServicioImagen {

    @Autowired RepositorioImagen repo;

    public List<Imagen> getAll(){
        return repo.findAll();
    }

    public void saveImage(Imagen im) {
        repo.save(im);
    }

和控制器：

@Controller
public class Controlador {
    @Autowired private ServicioImagen servicioImagen;

    private void someMethod(){
        servicioImagen.getAll().forEach(e -> System.out.println(e));

        Imagen imagen = new Imagen();
        imagen.setNombre("SOMENAME");
        servicioImagen.saveImage(imagen);

        servicioImagen.getAll().forEach(e -> System.out.println(e));
    }

}

我在创建数据库时在表中插入了一些默认记录，getAll() 方法可以很好地检索它们，但是当我save() 一个新 bean 时，它不会保留在数据库中（getAll() 检索相同信息和以前一样）。我在this 中阅读了打开记录器的答案，然后我发现 Hibernate 甚至提交了查询。我不知道还要做什么，这是插入的日志：

我还注意到查询提交在连接关闭（时间戳2020-03-07 18:33:55.720 for Ctrl+F），我不知道它是否与持久性有关。

【问题讨论】：

你是如何调用someMethod的？
其实它是JavaFX的一个按钮动作，但我100%确定它被调用了。我没有将其添加到问题中，因为它毫无意义。
您不确定该函数是否被调用并且您认为它无关紧要？
不，我 100% 确定该函数已被调用，我说作为 JavaFX onAction 方法的函数对于添加到问题中毫无意义。

【解决方案1】：

我终于成功了，我不知道为什么，但我发布了我是如何做到的，以防它对某人有所帮助。

我的配置文件如下所示：

@Configuration
@EnableTransactionManagement
public class SpringConfig {
    @Bean
    public DataSource dataSource() {
        DriverManagerDataSource dataSource = new DriverManagerDataSource();
        dataSource.setDriverClassName("org.hsqldb.jdbcDriver");

        String ruta = System.getProperty("user.home") + "\\path\\to\\my\\db";
        String url = "jdbc:hsqldb:file:" + ruta;
        dataSource.setUrl(url);

        dataSource.setUsername("SA");
        dataSource.setPassword("");

        return dataSource;

    }

    @Bean
    public LocalSessionFactoryBean sessionFactory() {
        LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
        sessionFactory.setDataSource(dataSource());
        sessionFactory.setPackagesToScan("com.bcadaval.memefinder3020.modelo.beans");

        return sessionFactory;
    }



    @Bean
    public PlatformTransactionManager transactionManager() {
        HibernateTransactionManager transactionManager = new HibernateTransactionManager();
        transactionManager.setSessionFactory(sessionFactory().getObject());
        return transactionManager;
    }


    @Bean
    public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
          LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
          em.setDataSource(dataSource());
          em.setPackagesToScan("com.bcadaval.memefinder3020.modelo.beans");     
          JpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
          em.setJpaVendorAdapter(vendorAdapter);
          return em;
       }
}

我做了一些改动：

@Configuration
@EnableTransactionManagement
public class SpringConfig {
    @Bean
    public DataSource dataSource() { /* the same as before */}

    @Bean
    public EntityManager entityManager() {
        return entityManagerFactory().createEntityManager();
    }

    @Bean
    public EntityManagerFactory entityManagerFactory() {

          LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
          em.setDataSource(dataSource());
          em.setPackagesToScan("com.bcadaval.memefinder3020.modelo.beans");     
          JpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
          em.setJpaVendorAdapter(vendorAdapter);
          em.setPersistenceUnitName("default");
          em.afterPropertiesSet();
          return em.getObject();
       }
}

As CodeSlave said，我需要flush()，然后我收到了那个异常，但是在删除LocalSessionFactoryBean bean 后，所有的都开始工作了。我什至尝试删除 EntityManager 和 EntityManagerFactory bean 并且它仍然工作正常，但我不知道我应该保留它们还是删除它们。我想对此给出更明确的答案，但我是 Hibernate 的新手，我想我是在无意识地配置一个 Hibernate/Spring 不会使用的事务管理器或类似的东西。

【解决方案2】：

这是因为在您尝试从数据库中获取数据之前事务没有关闭。

尝试使用saveAndFlush(); 而不是save();

【讨论】：

我试过了，但是抛出异常：Caused by: org.springframework.dao.InvalidDataAccessApiUsageException: no transaction is in progress; nested exception is javax.persistence.TransactionRequiredException: no transaction is in progress
尝试使用@Transactional为您服务。
用@Transactional注释服务是一种巨大的代码味道
同样，我尝试了 @Transactional 注释（javax 和 springframework），但仍然抛出异常，甚至在 Spring 配置文件中添加/删除 @EnableTransactionManagement。日志告诉它在异常发生后回滚，希望如此。
@Andronicus 不，它很好，这里是日志消息：rolling back - Preparing to rollback transaction via JDBC Connection.rollback() - Transaction rolled-back via JDBC Connection.rollback() - LogicalConnection#afterTransaction - Releasing JDBC resources - re-enabling auto-commit on JDBC Connection after completion of JDBC-based transaction
