public class Test {

public static void main(String[] args) throws SQLException {
// TODO Auto-generated method stub

String url="jdbc://mysql://localhost:3306/user";
String user="root";
String password="123456";
Connection conn=null;
try {
Class.forName("com.mysql.jdbc.Driver");
DriverManager.getConnection(url, user, password);
System.out.println("链接数据库成功");
} catch (ClassNotFoundException | SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}finally {
conn.close();
}
}

}

应该是你的项目没有导入mysql驱动包。
如：mysql-connector-java-5.1.45.jar。
