Hibernate和Oracle 12c：未知的Oracle主要版本[12]：无法确定要使用的方言[name = Oracle，majorVersion = 12]

Question

Oracle连接错误。

WARN: HHH000384: Unknown Oracle major version [12]

Persistance.xml

<persistence-unit name="IntegratorMasterdataPU" transaction-type="JTA" >

        <property name="hbm2ddl.auto" value="create" />
    </properties>
</persistence-unit>

代码：

public static void main(String[] args) {

    EntityManagerFactory emf = Persistence.createEntityManagerFactory("IntegratorMasterdataPU");
    em = emf.createEntityManager();

}

Maven依赖项：

<dependencies>
    <dependency>
        <groupId>org.eclipse.persistence</groupId>
        <artifactId>javax.persistence</artifactId>
        <version>2.0.0</version>

我是否需要更改提供者的持久性？如果是，那又如何？还是在hibernate.connection.driver_class中有问题？

Answer 1

命中和试验，并使用Persistance.xml中的以下属性修复：

        <property name="hibernate.connection.driver_class" value="oracle.jdbc.OracleDriver" />
        <property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect" />
