JAVA连接SQL显示驱动加载失败请问怎么解决

at java.awt.EventDispatchThread.pumpEventsForHierarchy(Unknown Source)
at java.awt.EventDispatchThread.pumpEvents(Unknown Source)
at java.awt.EventDispatchThread.pumpEvents(Unknown Source)
at java.awt.EventDispatchThread.run(Unknown Source)
这是报错

查看驱动包是否导入成功


驱动名写错没，//加载驱动
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");


url写错 //数据库连接URL
String url="jdbc:sqlserver://localhost:1433;DatabaseName=Student";


jar包有问题没

如果什么都是对的就project___的clean对应项目
