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.*" % 
!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上传新闻/title 
/head 
body 
%! // 字符处理函数 换行符变成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 {

 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="***";

 pstmt.setString(5, date);
 i = pstmt.executeUpdate();
 conn1.close();
 pstmt.close();
 out.println("br上传成功");
} catch (Exception e) {
