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(" ")) + " " + 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("<br>上传成功"); } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } %> </body> </html>
