jsp实现textarea中的文字保存换行空格存到数据库的方法

UploadNews.jsp

<%@ page language="java" contentType="text/html; charset=utf-8"
 pageEncoding="utf-8"%>








 

  

   

    
title      
    
   
   

    
author  
    
   
   

    

   
   

    
date(xxxx.xx.xx)
    
   
   

    

      
     
   
   

    

   
  
 

换行函数在ShangchuanNews.jsp 代码如下

<%@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.*" %> 
 

 
 
 
 
 
 
<%! // 字符处理函数 换行符变成

public String turn(String str) { 
 while (str.indexOf("\n") != -1) { 
  str = str.substring(0, str.indexOf("\n")) + "
" 
    + str.substring(str.indexOf("\n") + 1); 
 } 
 while (str.indexOf(" ") != -1) { 
  str = str.substring(0, str.indexOf(" ")) + " " 
    + 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";//存到数据库不会乱码
 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("
上传成功");
} catch (Exception e) {
 // TODO Auto-generated catch block
 e.printStackTrace();
}
%>
