＆＃13;

我有什么方法可以这样做，如果有，我有错误的解决方案吗？

Answer 1

jdbc:sqlserver://[serverName[\instanceName][:portNumber]][;property=value[;property=value]]

这是连接URL的格式。你的工作吗？

Answer 2

我认为您不希望http：//在那里，对于正确的URL，您可能需要MySQL：// - 或 - http：//不是两者。

我猜你正确的字符串将是：

JDBC：MySQL的：//danu6.it.nuigalway.ie：3306 / mydb1899 /播放器

将代码写入数据库html的问题
