如何实现JSP页面中的表单信息保存到Mysql数据库啊？

获取表单中的信息，然后插入到Mysql中 
<%@ page language="java" contentType="text/html; charset=gbk"
    pageEncoding="gbk"%>

<%
int id = Integer.parseInt(request.getParameter("id"));
int rootid = Integer.parseInt(request.getParameter("rootid"));

%>








 ">
 ">

 
  
   
  
 

 
  
   
  
 

 
  
   
  
 





---------------------------------------------------------------
下面接收上面表单中传过来的信息，并插入到mysql中

<%@ page language="java" contentType="text/html; charset=gbk"
    pageEncoding="gbk"%>
<%@ page import="java.sql.*" %>

<%
request.setCharacterEncoding("GBK");
int id = Integer.parseInt(request.getParameter("id"));
int rootid = Integer.parseInt(request.getParameter("rootid"));
String title = request.getParameter("title");
String cont = request.getParameter("cont").replaceAll("\n","
");

Connection conn = null;
Statement st = null;

Class.forName("com.mysql.jdbc.Driver");
conn = DriverManager.getConnection("jdbc:mysql://localhost/bbs?user=root&password=690115399");
st = conn.createStatement();

conn.setAutoCommit(false);

String sql = "insert into article values(null,?,?,?,?,now(),0)";
PreparedStatement pstmt = conn.prepareStatement(sql);
pstmt.setInt(1,id);
pstmt.setInt(2,rootid);
pstmt.setString(3,title);
pstmt.setString(4,cont);
pstmt.executeUpdate();

st.executeUpdate("update article set isleaf = 1 where id = " + id);

conn.commit();
conn.setAutoCommit(true);

st.close();
pstmt.close();
conn.close();
%>







<%response.sendRedirect("ShowArticleTree.jsp"); %>


当然最好的方法还是应该用jsp + JavaBean方式。

最好写个SERVLET的类，通过获取表单页面的信息，在通过SQL语句保存到数据库里面

参考我写的这个吧，不想再写第二遍了，应该能看懂的。。
