在Hibernate 4中获取本机Oracle连接的句柄以运行存储过程

这是一项后续行动

我已经尝试了列出的答案中的选项，但出现了错误，无法将代理连接打开到Oracle需要的本机连接中

选项2代码

public void execute(Connection connection) throws SQLException {
    OracleConnection oracleConnection = connection.unwrap( OracleConnection.class );
    ...
}

错误

选项3代码

public void execute(Connection connection) throws SQLException {
    Connection unproxiedConnection = ( (JdbcWrapper<Connection>) connection ).getWrappedObject();
    ...
}

有什么建议吗

我也尝试过这个选项，但是这个类根本没有被实例化

更新：

选项2代码工作正常。问题是我们有两个版本的ojbc.jar-一个作为Jboss模块，另一个在EAR中，因此出现了异常。

选项2代码工作正常

即

OracleConnection OracleConnection=connection.unwrap OracleConnection.class

问题是我们有两个版本的ojbc.jar——一个作为Jboss模块，另一个在EAR中，因此出现了ClassCastException

如评论中所述，此代码也适用

oracle.jdbc.driver.OracleConnection oc=oracle.jdbc.driver.OracleConnection connection.getMetaData.getConnection

试试下面的方法

我也遇到了同样的问题。我们使用的是spring，它有一个名为 NativeJdbcExtractor。它有许多实现，下面的一个适用于TomCat。Jboss有一个特定的实现，称为JBossNativeJdbcExtractor

<bean id="jdbcExtractor" class="org.springframework.jdbc.support.nativejdbc.CommonsDbcpNativeJdbcExtractor"></bean>

为什么选项3代码会导致该错误？您从未尝试将连接强制转换为Oracle连接。通常，您需要了解连接池和数据源通常也会包装连接。对于选项2代码，Hibernate只需将该调用委托给它所拥有的底层连接。但这导致了一个错误。因此，在该连接的展开方法中存在错误。我假设这是JBoss WrappedConnectionJDK6类。你有选项2的完整堆栈跟踪吗？@Steve Ebersole:我们通过了这个oracle.jdbc.driver.OracleConnection oc=oracle.jdbc.driver.OracleConnection.getMetaData.getConnection；不知道为什么你会认为这会奏效。如果有东西代理驱动程序，一般来说，它并不只是代理连接。正如我已经问过的，你有选项2错误的完整异常输出吗？@SteveEbersole:Option 2有效-请查看我的更新。谢谢你抽出时间。
