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();
}
