【问题描述】：
我有一个利用 java 8 的 spring boot 应用程序，并且到目前为止使用了 hibernate 4。但是，我需要更改模型的一部分以包含 java8 提供的新 ZonedDateTime 类，即我需要一个数据时间类型，它为我提供 UTC 时间的实例以及偏移量和时区。出于这个原因，我想拥有原生的 hibernate 5 支持。我已经在我的 pom 中替换了这些部件：
//<dependency>
// <groupId>org.hibernate</groupId>
// <artifactId>hibernate-core</artifactId>
// <version>4.3.10.Final</version>
//</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-java8</artifactId>
<version>5.0.0.CR2</version>
</dependency>
我已经在我的 SpringPercisence 配置类中更改为使用休眠 5 而不是休眠 4，即
@Bean
public org.springframework.orm.hibernate5.LocalSessionFactoryBean sessionFactory() {
// org.springframework.orm.hibernate4.LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
org.springframework.orm.hibernate5.LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
sessionFactory.setDataSource(this.dataSource());
sessionFactory.setPackagesToScan("org.test");
sessionFactory.setHibernateProperties(hibernateProperties());
return sessionFactory;
}
@Bean
// public org.springframework.orm.hibernate4.HibernateTransactionManager transactionManager() {
public org.springframework.orm.hibernate5.HibernateTransactionManager transactionManager() {
HibernateTransactionManager txManager = new HibernateTransactionManager();
txManager.setSessionFactory(sessionFactory().getObject());
return txManager;
}
@Bean
public PersistenceExceptionTranslationPostProcessor exceptionTranslation() {
return new PersistenceExceptionTranslationPostProcessor();
}
@Bean
public Properties hibernateProperties() {
return new Properties() {
{
setProperty("hibernate.dialect", "org.hibernate.dialect.PostgreSQLDialect");
setProperty("hibernate.chach.provider_class", "org.hibernate.cache.NoCacheProvider");
setProperty("hibernate.show_sql", "true");
// setProperty("hibernate.hbm2ddl.auto", "create");
setProperty("hibernate.hbm2ddl.auto", "create-drop");
// setProperty("hibernate.hbm2ddl.auto", "update");
}
};
}
我收到一个与上面配置的“sessionFactory”bean 有某种关联的错误，后来它说明了有关 ImplicitNamingStrategy 的内容。我在这里读过
http://in.relation.to/2015/03/31/hibernate-orm-500-beta-1-release/
hibernate NamingStrategy 已被删除，但我不明白这到底是什么意思。由于我找不到 hibernat 和 spring4 的示例，我希望有人可以帮助我解决这个问题。

【问题讨论】：
-
你用的是哪个Spring Boot版本和Spring Version？
-
@M.Deinum 我正在使用 spring-boot-starter-parent 1.2.5.RELEASE
-
@M.Deinum shell 我粘贴了整个 pom 文件？它很长，但我相信这与休眠 5 的一些配置问题有关，即 ImplicitNamingStrategy。
-
不，这是因为 Spring Boot 1.2 使用不支持 Hibernate 5 的 Spring 4.1，因此您可能将版本中的 Spring Framework 的（部分）升级到 4.2 以及如何升级支持 hibernate 5 的版本取决于版本。 Spring 4.2 和 hibernate 5 都没有准备好生产，它们还不是最终版本。
-
@M.Deinum 感谢您的回复。我刚刚尝试将整个应用程序升级到 spring-boot-starter-parent 版本 1.3.0.M2 删除了所有外部 pom 引用和所有版本声明，这是同样的问题。基本上我的问题是如何使用 ZonedDateTime 类，因此它在 postgresql 中显示它包括时区和时间偏移。我已经厌倦了多个东西，例如“@Temporal(TemporalType.TIMESTAMP)”时间注释或使用“@Type(type="org.jadira.usertype.dateandtime.jsr310.PersistentZonedDateTime")”，但都没有按预期工作.
