------解决方案--------------------
你登录数据库难道不用账号和密码么

只有一个url不能连接数据库诶、

10: conn=DriverManager.getConnection(url,username,passsword);


------解决方案--------------------
你的username和password呢?
10: conn=DriverManager.getConnection(url,username,passsword);
------解决方案--------------------
conn=DriverManager.getConnection(url,username,passsword);
------解决方案--------------------
把你连接sql server的代码贴出看看，就知道拉。
------解决方案--------------------
你的sql jdbc是放在哪里？

探讨

String url="jdbc:sqlserver://localhost;integratedSecurity=true;DatabaseName=student";
