我正在尝试浏览GroovySQL上的tutorial。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在.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：

如何在Groovy shell中使用Oracle JDBC驱动程序？
答案 0 :(得分：2)
运行没有SecurityManager的shell，不允许注册新的MBeans（这就是异常所说的内容）。
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，则会打开系统以进行各种攻击。
OTOH，使用标准工具配置SecurityManager是如此复杂，以至于我很确定没有人能够解决任何非平凡的例子，所以问题是安装它的痛苦是否超过了获得安全保障。
