UploadNews.jsp

<%@ page language="java" contentType="text/html; charset=utf-8"
 pageEncoding="utf-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>上傳新聞</title>
<SCRIPT LANGUAGE="JavaScript">
function upload(){
 document.getElementById("article").value = document
 .getElementById("content").value;
 document.getElementById("formid").submit();
 }
</SCRIPT>
</head>
<body>
 <form method="post" action="ShangchuanNews.jsp" id="formid">
  <table border="0" align="center">
   <tr>
    <td>title&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<input type="text"
     name="title" value="a" size="40">
    </td>
   </tr>
   <tr>
    <td>author&nbsp;&nbsp;<input type="text" name="author"
     size="40">
    </td>
   </tr>
   <tr>
    <td><input type="hidden" id="article"
     name="articleName" /></td>
   </tr>
   <tr>
    <td>date(xxxx.xx.xx)<input type="text" name="date" size="40">
    </td>
   </tr>
   <tr>
    <td><div align="center">
      <input type="button" value="submit" class="btn2" onclick = "upload();" />
     </div></td>
   </tr>
   <tr>
    <td><textarea rows="30" cols="80" id="content"></textarea></td>
   </tr>
  </table>
 </form>
</body>
</html>

換行函數(shù)在ShangchuanNews.jsp 代碼如下

<%@page import="java.io.PrintWriter"%>
<%@page import="java.net.URLDecoder"%>
<%@ page language="java" contentType="text/html; charset=utf-8" 
 pageEncoding="utf-8" %> 
<%@ page import="java.sql.*" %> 
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> 

<html> 
<head> 
<meta http-equiv="Content-Type" content="text/html; utf-8"> 
<title>上傳新聞</title> 
</head> 
<body> 
<%! // 字符處理函數(shù) 換行符變成<br>
public String turn(String str) { 
 while (str.indexOf("\n") != -1) { 
  str = str.substring(0, str.indexOf("\n")) + "<br>" 
    + str.substring(str.indexOf("\n") + 1); 
 } 
 while (str.indexOf(" ") != -1) { 
  str = str.substring(0, str.indexOf(" ")) + "&nbsp" 
    + str.substring(str.indexOf(" ") + 1); 
 } 
 return str; 
} 
%>
<% 
try {
 request.setCharacterEncoding("utf-8");
 String title = request.getParameter("title");
 String author = request.getParameter("author");
 String article = request.getParameter("articleName");
 String articlebr = turn(article);
 String date = request.getParameter("date");
 String driverClass="com.mysql.jdbc.Driver";
 String url = "jdbc:mysql://****.****/****?characterEncoding=utf8";//存到數(shù)據(jù)庫不會(huì)亂碼
 String user="***"; 
 String password="****";
 Connection conn;
 int i=0;
 Class.forName(driverClass).newInstance();
 conn = DriverManager.getConnection(url,user,password);
 String sql = "insert into news (id,title,author,article,date) "
   + "values(?,?,?,?,?)";
 Connection conn1 = DriverManager.getConnection(url, user, password);
 PreparedStatement pstmt;
 pstmt = (PreparedStatement) conn1.prepareStatement(sql);
 pstmt.setString(1, null);
 pstmt.setString(2, title);
 pstmt.setString(3, author);
 pstmt.setString(4, articlebr);
 pstmt.setString(5, date);
 i = pstmt.executeUpdate();
 conn1.close();
 pstmt.close();
 out.println("<br>上傳成功");
} catch (Exception e) {
 // TODO Auto-generated catch block
 e.printStackTrace();
}
%> 
</body>
