Spring 4 with hibernate 5.2 Configuration（将hibernate 4移动到5.2）：无法启动tomcat服务器

Question

以下是此 Hibernate 5 + spring 4 集成的错误日志。

@Configuration
@EnableTransactionManagement
@ComponentScan(basePackages = { "com.social.*","com.*" })
public class HBConfig {

   @Bean
   public LocalSessionFactoryBean getSessionFactory() {
      LocalSessionFactoryBean factoryBean = new LocalSessionFactoryBean();

      Properties props = new Properties();
      // Setting JDBC properties
      props.put(DRIVER, "com.mysql.cj.jdbc.Driver");
      props.put(URL, "jdbc:mysql://localhost:3306/socialdev");
      props.put(USER, "root");
      props.put(PASS,"123");

      // Setting Hibernate properties
      props.put(SHOW_SQL, true);
      props.put(HBM2DDL_AUTO, "update");

      // Setting C3P0 properties
      props.put(C3P0_MIN_SIZE, 5);
      props.put(C3P0_MAX_SIZE, 20);
      props.put(C3P0_ACQUIRE_INCREMENT, 1);
      props.put(C3P0_TIMEOUT, 1800);
      props.put(C3P0_MAX_STATEMENTS, 150);

      factoryBean.setHibernateProperties(props);
      factoryBean.setPackagesToScan("com.social.entity");

      return factoryBean;
   }

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

以上是配置。让我知道我在做什么错误，使用相同的代码库 hibernate 4 对我来说工作正常。

Answer 1

这可能是版本不匹配问题，我在升级到 Hibernate 5.2 时遇到过这个问题。

事实上，stackoverflow 上有多个线程，但我找不到确切的解决方案，直到我发现 Spring 记录了支持 Hibernate 5.2 的问题，您可以在 https://github.com/spring-projects/spring-framework/issues/18899 参考该问题

就解决方案而言

• 将你的 spring 版本升级到最新的 4.3.x 系列，从今天起你可以迁移到 Spring 4.3.30.RELEASE
• 既然您已经迁移到 Hibernate 5.2，请确保所有 Hibernate 工件版本都是 5.2.x

这应该可以解决您的问题，

  @Bean
  public DataSource dataSource() {
    return DataSourceBuilder.create().build();
  }


  @Bean
  @Primary
  public PlatformTransactionManager transactionManager(EntityManagerFactory entityManagerFactory) {
    JpaTransactionManager transactionManager = new JpaTransactionManager();
    transactionManager.setEntityManagerFactory(entityManagerFactory);
    return transactionManager;
  }

  @Bean
  @Primary
  public EntityManagerFactory entityManagerFactory(DataSource dataSource,
    JpaVendorAdapter jpaVendorAdapter) {
    LocalContainerEntityManagerFactoryBean lef = new LocalContainerEntityManagerFactoryBean();
    lef.setDataSource(dataSource);
    lef.setJpaVendorAdapter(jpaVendorAdapter);
    Properties props = new Properties();
  props.put(DRIVER, "com.mysql.cj.jdbc.Driver");
  props.put(URL, "jdbc:mysql://localhost:3306/socialdev");
  props.put(USER, "root");
  props.put(PASS,"123");

  // Setting Hibernate properties
  props.put(SHOW_SQL, true);
  props.put(HBM2DDL_AUTO, "update");

  // Setting C3P0 properties
  props.put(C3P0_MIN_SIZE, 5);
  props.put(C3P0_MAX_SIZE, 20);
  props.put(C3P0_ACQUIRE_INCREMENT, 1);
  props.put(C3P0_TIMEOUT, 1800);
  props.put(C3P0_MAX_STATEMENTS, 150);

    props.setProperty("hibernate.dialect", "org.hibernate.dialect.Oracle10gDialect");
    lef.setJpaProperties(jpaProperties);
    //lef.setPersistenceProvider(new HackedHibernatePersistence());
    lef.setPackagesToScan("com.social.entity");
    lef.afterPropertiesSet();
    
    return lef.getObject();
  }
