Java Oracle驱动程序错误Oracle.jdbc.Driver.T4CConnection.isValid（I）Z

我正在使用从Oracle站点分发的ojdbc7.jar，到目前为止，它工作得非常好。然而，最近，我们决定使用maven结构来开发我们的Web应用程序，所以我一直在将Java Web应用程序转换为maven。现在，在建立oracle DB连接时，我看到了这个oracle.jdbc.driver.T4CConnection.isValidIZ错误，尽管我使用的驱动程序文件与非maven版本中的驱动程序文件完全相同。我的依赖项声明如下：

<dependency>
    <groupId>com.oracle</groupId>
    <artifactId>ojdbc</artifactId>
    <version>7</version>
</dependency>

您需要运行maven安装文件，因为maven无法下载它

你升级了Java吗？mavenized ur web app之前使用的是哪个版本？现在使用的是哪个版本？您介意发布完整的堆栈跟踪吗？我们使用的是Java 1.7，是的，我将在问题中发布堆栈跟踪。我已经发布了，它不起作用。我仍然会遇到同样的错误，而且只有在使用Maven时才会出现。
