如何将JSP页面中的表单信息保存到Mysql数据库？
展开全部
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"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<%
int id = Integer.parseInt(request.getParameter("id"));
int rootid = Integer.parseInt(request.getParameter("rootid"));
%>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gbk">
<title>Replay</title>
</head>
<body>
<form method="post" action="ReplayOK.jsp">
<input type="hidden" name="id" value="<%=id %>">
<input type="hidden" name="rootid" value="<%=rootid %>">
<table align="center">
<tr>
<td>
<input type="text" name="title" size="80">
</td>
</tr>
<tr>
<td>
<textarea cols="80" rows="20" name="cont"></textarea>
</td>
</tr>
<tr>
<td>
<input type="submit" value="提交">
</td>
</tr>
</table>
</form>
</body>
</html>

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.*" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<%
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","<br/>");
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();
%>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gbk">
<title>Insert title here</title>
</head>
<body>
<%response.sendRedirect("ShowArticleTree.jsp"); %>
</body>
</html>
当然最好的方法还是应该用jsp + JavaBean方式。
