数据库连接代码 （javaBean）

public class DataCon {
     private static final String Driver = "com.mysql.jdbc.Driver";//jar包驱动
     private static final String url = "jdbc:mysql://localhost:3306/myhome";//数据库连接路径，数据库名
     private static final String user = "root";//数据库用户名
     private static final String password = "root";//数据库密码
        
        
     public Connection getConnction(){
     Connection con = null;
     try {
     Class.forName(Driver);//引用驱动
     con = DriverManager.getConnection(url, user, password);//数据库连接
                
     } catch (Exception e) {
     e.printStackTrace();
     }
     return con;
     }
    
    
    //关闭数据库
     public void closeAll(ResultSet rs, PreparedStatement ps, Connection con)
     {
     try {
     rs.close();
     ps.close();
     con.close();
     } catch (Exception e) {
     e.printStackTrace();
     }
