无法在 groovysh 中加载 oracle.jdbc.driver.OracleDriver？

Question

我正在尝试通过 GroovySQL 上的 tutorial。我需要连接的数据库是 Oracle 数据库。于是我下载了ojdbc6.jar，放到~/.groovy/lib/。如果我将以下脚本放在 .groovy 文件中，我可以执行groovy testScript.groovy 并且会成功：

import oracle.jdbc.driver.OracleDriver
println(OracleDriver.getCompileTime())

当我尝试通过groovysh 做同样的事情时，我收到以下错误：

如何在 Groovy shell 中使用 Oracle JDBC 驱动程序？

Answer 1

在没有 SecurityManager 的情况下运行 shell，不允许注册新的 MBeans（这就是异常所说的）。

在 Groovy shell 的启动脚本中查找 -Djava.security.manager 或在源代码中查找 System.setSecurityManager()。

请注意，如果您这样做，您的系统就会受到各种攻击。

OTOH，使用标准工具配置 SecurityManager 非常复杂，我敢肯定没有人能正确地完成任何不平凡的示例，所以问题是安装一个的痛苦是否超过了收益安全。
