Java Connection Database

The basic code is as follows:

String driver= "Com.mysql.jdbc.Driver";
String url= "Jdbc:mysql:/localhost:3306/project";
String user= "root";
String password= "Wang";
Public Dbconn () {

}
Public Connection Getconn () {
Connection Conn=null;
try{
Class.forName (driver);
Conn=drivermanager.getconnection (Url,user,password);
System.out.println ("Database linked success!");
}catch (Exception e) {
System.out.println ("Link failed!");
E.printstacktrace ();
}
Return conn;
}

It is worth noting that in a regular Java project, the database driver file can be loaded into the program directly with Bulidpath, but in a Web project, the driver file needs to be put into web-inf/lib, or the program will not be able to read the database file
