最简单的jdbc操作

 1 Connection con = null;
 2         Statement stmt = null;
 3         
 4         // 保存到表中
 5         String sql = "insert into website(username,userpassw) values('喜欢','不喜欢')";
 6         
 7         try {
 8             Class.forName("com.mysql.jdbc.Driver");
 9             //链接对象
10             con = DriverManager.getConnection("jdbc:mysql://127.0.0.1/mysqlconnect", "root", "bequt");
11             //执行命令对象
12             stmt = con.createStatement();
13             //执行
14             stmt.execute(sql);
15             //关闭
16             stmt.close();
17             con.close();
18         } catch (Exception e) {
19             // TODO Auto-generated catch block
20             e.printStackTrace();
21         }
