JSP中的数据库操作(3):JSP页面中的数据库插入
这次是怎样将大象放冰箱的命题了!大家都懂的!
我们要解决的主要有两个问题:
1、如何获取输入的内容
2、如何插入时间。
直接上代码
[html]
<%@ page language="java" import="java.util.*, java.sql.*" pageEncoding="gb2312"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<%request.setCharacterEncoding("UTF-8");%>
<%response.setCharacterEncoding("UTF-8");%>

<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />

<body>
<form method=post>

//连接MySQL数据库
Class.forName("com.mysql.jdbc.Driver").newInstance();
String url="jdbc:mysql://localhost:3306/news";
String user="root";
String password="1234";
Connection conn = DriverManager.getConnection(url, user, password);
Statement st = conn.createStatement();
%>
<table >
<tr>
<td width="174" id="title">标题</td>
<td width="449" id="title">内容</td>
<td width="161" id="title">时间</td>
</tr>
<%
ResultSet rs = st.executeQuery("SELECT * FROM data ORDER BY id DESC LIMIT 10");
while(rs.next()){%>
<tr>
<td width="174" ><%=rs.getString("title") %></td>
<td width="449" ><%=rs.getString("content") %></td>
<td width="161"><%=rs.getString("time") %></td>
</tr>
<%} %>
</table>
<%
//通过input中的name获取输入的内容。time那一行是获得时间及定义时间格式
String getTitle=request.getParameter("title");
String getContent=request.getParameter("content");
java.text.SimpleDateFormat time = new java.text.SimpleDateFormat( "yyyy-MM-dd HH:mm:ss");
String insertSQL = "INSERT INTO data(title, content, time) Values ('"+getTitle+"', '"+getContent+"', ' "+time.format(new java.util.Date())+"')";
st.executeUpdate(insertSQL);
%>
<%
rs.close();
st.close();
conn.close();
%>
</body>
</html>
