Answer 4

首先你有sqlserver的jdbc驱动么String driverName = "com.microsoft.jdbc.sqlserver.SQLServerDriver";
String dbURL = "jdbc:microsoft:sqlserver://localhost:1433; DatabaseName=pubs";
//检查你的端口是否修改过，然后是你数据库的名称，以及你连数据库的用户名，密码
String userName = "sa";
String userPwd = "";
Connection dbConntry {
Class.forName(driverName);
dbConn = DriverManager.getConnection(dbURL, userName, userPwd);
System.out.println("Connection Successful!");
}
Catch (Exception e) {
e.printStackTrace();
}
