最简单的jdbc操作

 Connection con = null;
         Statement stmt = null;

         // 保存到表中
         String sql = "insert into website(username,userpassw) values('喜欢','不喜欢')";

         try {
             Class.forName("com.mysql.jdbc.Driver");
             //链接对象
             con = DriverManager.getConnection("jdbc:mysql://127.0.0.1/mysqlconnect", "root", "bequt");
             //执行命令对象
             stmt = con.createStatement();
             //执行
             stmt.execute(sql);
             //关闭
             stmt.close();
             con.close();
         } catch (Exception e) {
             // TODO Auto-generated catch block
             e.printStackTrace();
         }
