使用Java连接到MySql数据库

Question

So I've been teaching myselft mysql and am trying to integrate it into my Java code. I've looked at some past code snippets and tutorials and I can't seem to figure out why my code is incorrect. (removed password for obvious reasons)

Here's what I'm using to connect

  public static void connectionToMySql(){
    String host = "mysql9.000webhost.com";
    String username = "a9808220_pin";
    String pass = "";
    try{
        Class.forName("com.mysql.jdbc.Driver").newInstance();
        Connection connection = DriverManager.getConnection(host,username,pass);
      /*insert code*/
        connection.close();
        System.out.println("It worked :)");

    } catch (Exception e) {
        System.out.println("Something went wrong :(");
        e.printStackTrace();
    }
}

I get an exception that there's no suitable driver. I'm not sure why because I have the jar downloaded and pathed correctly

Answer 1

String host should be like

String host = "jdbc:mysql:ip:port"//ip or hostname

example code that works for me...

        Connection conn = DriverManager.getConnection("jdbc:mysql://localhost:1433;"
                 +"databaseName=test;"
                 +"user=sa;"
                 +"password=xxxxx;");
         System.out.println("connected");

Answer 2

Your connection should be a JDBC URL in the form

String url = "jdbc:mysql://mysql9.000webhost.com:3306/";

Now in order for this to work you should:

1) Verify that mySQL is running on the host mysql9.000webhost.com

2) Verify that the port is the default port ie 3306, if not change the code above to use the right port
