用的是MySQL数据库。

1，建一个userdb库，再建userinfo表，字 段：id(int),username(varchar),password(varchar)。

create database userdb; 
use userdb; 
create table userinfo( 
id int(10) not null auto_increment, 
username varchar(20), 
password varchar(20), 
primary key(id)); 
  create database userdb;  use userdb;  create table userinfo(  id int(10) not null auto_increment,  username varchar(20),  password varchar(20),  primary key(id));
2，DBConnection.java

        String driver = "com.mysql.jdbc.Driver"; 
        String url = "jdbc:mysql://localhost:3306/userdb"; 
        String username = "root"; 
        String password = "mysql"; 
        Class.forName(driver); 
        conn = DriverManager.getConnection(url, username, password); 
        return conn; 
    } 
}
