مشکل وصل شدن به MYSQL
سلام
باسه وصل شدن به mysql از تکه کد زیر تو سرور استفاده کردم :
public void connect() {
Connection conn = null;
String url = "jdbc:mysql://localhost:3306/";
String db = "bible";
String driver = "com.mysql.jdbc.Driver";
String user = "root";
String pass = "admin";
try {
Class.forName(driver).newInstance();
} catch (InstantiationException e) {
System.out.print("<MYSQL:InstantiationException>") ;
} catch (IllegalAccessException e) {
System.out.print("<MYSQL:IllegalAccessException>") ;
} catch (ClassNotFoundException e) {
System.out.print("<MYSQL:ClassNotFoundException>") ;
}
try {
conn = DriverManager.getConnection(url+db, user, pass);
System.out.print("<MYSQL:Enjoy!>");
} catch (SQLException e) {
System.err.println("Mysql Connection Error: ");
e.printStackTrace();
//System.out.print("<MYSQL:Can't Connect>");
}
}
اما ارور زیر رو میده :
Mysql Connection Error:
com.mysql.jdbc.exceptions.jdbc4.CommunicationsExce ption: Communications link failure
The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.
