Hibernate Oracle 12c unable to determine dialect
提问by user3249353
I am trying to connect to Oracle 12c using hibernate version 3.6.10.Final. When i do org.hibernate.cfg.configuration.buildSessionFactory()
我正在尝试使用休眠版本 3.6.10.Final 连接到 Oracle 12c。当我做 org.hibernate.cfg.configuration.buildSessionFactory()
I get
我得到
org.hibernate.HibernateException: Unable to determine Dialect to use [name=Oracle, majorVersion=12]; user must register resolver or explicitly set 'hibernate.dialect'.
org.hibernate.HibernateException：无法确定方言使用 [name=Oracle，majorVersion=12]；用户必须注册解析器或明确设置“hibernate.dialect”。
When i am using Oracle 11g i don't have this problem the dialect is autodetected to org.hibernate.dialect.Oracle10gDialect. Why for Oracle 12c it doesn't work.
当我使用 Oracle 11g 时，我没有这个问题，方言会自动检测到 org.hibernate.dialect.Oracle10gDialect。为什么对于 Oracle 12c 它不起作用。
Thanks
谢谢

Hibernate in your version cannot guess what dialect to use with Oracle12c. However, you may force to use Oracle10 dialect.
您的版本中的 Hibernate 无法猜测与 Oracle12c 一起使用的方言。但是，您可能会强制使用 Oracle10 方言。
Here is a spring configuration and the databasePlatformproperty which does the job.
这是一个弹簧配置和databasePlatform完成工作的属性。
<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="jpaVendorAdapter">
<bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
<property name="generateDdl" value="true"/>
<property name="showSql" value="true" />
<!-- this property forces Oracle10 on Oracle12c since Hibernete cannot guess it! -->
<property name="databasePlatform" value="org.hibernate.dialect.Oracle10gDialect"/>
</bean>
</property>

Hibernate 3.6.10 doesn't support Oracle 12. StandardDialectResolver can't resolve the dialect for Oracle12
Hibernate 3.6.10 不支持 Oracle 12。StandardDialectResolver 无法解析 Oracle12 的方言
