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();
        }
