Java IO错误：网络适配器无法建立给定的连接错误

我想使用CSV阅读器将值上载到oracle数据库

我有这样的数据库连接

我得到了一些类似这样的错误，看起来我的连接是正确的，但是返回值给出了错误

在我与mysql的连接中，这段代码运行正常，但是当我尝试连接到oracle时，我遇到了这个错误。

好吧，你能ping一下机器吗？在

10.40.43.133:1526上没有数据库服务器在监听，或者它的防火墙阻止你向该主机/端口发送数据包。关于“连接超时：连接”有什么不清楚的？它无法连接到您的服务器。如果您确定您的连接
String
正确，则您的数据库已关闭。请检查连接设置、oracle server防火墙、您的应用程序是否可以看到oracle服务器等。
