Question

使用Vaadin 7我创建了一个简单的登录表单，将用户名和密码传递给管理与Oracle系统的数据库连接的类。然后该类登录并创建会话。

以下凭据有效：

用户名：User1

密码：密码1

这些凭据会抛出错误：

用户名：user1@email.com

密码：密码1

两者都是数据库中的有效用户。我已经通过在Oracle SQL Developer中使用上述凭据证实了这一点。

我怀疑JDBC驱动程序不喜欢“@”或“。”在用户名中。有没有办法可以转义任何一个字符，以便JDBC驱动程序在连接字符串中忽略它？

Answer 1

根据Oracle，这是一个错误（BUG-6362104）： JDBC驱动程序抛出MalformedObjectException或InstanceAlreadyExistsException 加载时。。尝试再次从OTN下载驱动程序。如果你想知道你是否有修补过的jar：

java -jar ojdbc6.jar

未修补的jar打印

Oracle 11.1.0.6.0-Production JDBC 5.0 complied with JDK1.6

和修补后的jar打印

Oracle 11.1.0.6.0-Production+ JDBC 5.0 complied with JDK1.6

请确保您拥有可用于Oracle数据库版本的最新JDBC驱动程序。
