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

Question

我正在尝试通过 tutorial在 GroovySQL 上。我需要连接的数据库是 Oracle 数据库。所以我下载了ojdbc6.jar并将其放入 ~/.groovy/lib/。如果我将以下脚本放入 .groovy 文件中，我可以执行 groovy testScript.groovy 并且它会成功:

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:

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

Answer 1

在没有 SecurityManager 的情况下运行 shell，它不允许注册新的 MBean(异常就是这么说的)。

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，如果这样做，您的系统将面临各种攻击。

OTOH，使用标准工具配置 SecurityManager 非常复杂，我很确定没有人能正确处理任何重要的示例，所以问题是安装的痛苦是否一个超过了安全方面的 yield 。
