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]
Exception in thread "main" javax.persistence.PersistenceException: [PersistenceUnit: IntegratorMasterdataPU] Unable to build EntityManagerFactory

Persistance.xml

<persistence-unit name="IntegratorMasterdataPU" transaction-type="JTA" >
    <provider>org.hibernate.ejb.HibernatePersistence</provider>
    <properties>
        <property name="hibernate.connection.url" value="jdbc:oracle:thin:@daq-esb-ora01.man.bosng.dk:1521/int_qa" />
        <property name="hibernate.connection.driver_class" value="org.hibernate.dialect.Oracle10gDialect" />
        <property name="hibernate.connection.username" value="ERDATA" />
        <property name="hibernate.connection.password" value="6g6gqn5" />
        <property name="hibernate.archive.autodetection" value="class" />

        <property name="hibernate.format_sql" value="true" />
        <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>
    </dependency>

    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-entitymanager</artifactId>
        <version>4.2.8.Final</version>
    </dependency>

    <dependency>
        <groupId>oracle</groupId>
        <artifactId>ojdbc6</artifactId>

        <artifactId>junit</artifactId>
        <version>3.8.1</version>
        <scope>test</scope>
    </dependency>
</dependencies>

我需要坚持更换供应商吗？如果是那么什么？或者这是 hibernate.connection.driver_class 中的一个问题？

Answer 1

命中和试炼并使用 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" />
