Question

尝试连接到允许远程连接的免费mysql数据库主机，但我收到此错误：

没有为jdbc找到合适的驱动程序：mysql：//xx2-23-x1-2x1-172.compuxe-1.xmazonaws.com:3306

我使用下面的代码

 try{
      Class.forName("com.mysql.jdbc.Driver");
    System.out.println("Driver loaded");
    }
    catch(ClassNotFoundException e){
        System.out.println(e.getMessage());
    }
    try{
       String host = "jdbc:mysql://xx2-23-x1-2x1-172.compuxe-1.xmazonaws.com:3306/xxxxx";
        conn = DriverManager.getConnection(host,"xxxxx","xxxxx");
        System.out.println("Connection Established");
    }

提前致谢。

EDIT

堆栈跟踪如下：

您应该使代码看起来如下：

try {
    Class.forName("com.mysql.jdbc.Driver");
    String host = "jdbc:mysql://xx2-23-x1-2x1-172.compuxe-1.xmazonaws.com:3306/xxxxx";
    conn = DriverManager.getConnection(host,"xxxxx","xxxxx");
} catch (Exception e) {
    e.printStackTrace();
}

同时验证MySQL JDBC库是否在您的类路径中。该库可以从here下载。
