JSP開發應用是,中文亂碼是個比較常見的問題,其根源是:Web容器默認的字符處理編碼是ISO-8859-1。
實例一、JSP頁面顯示時
- <html>
- <head>
- <title>中文亂碼——JSP頁面顯示時</title>
- </head>
- <body>
- <center>
- <br/>
- <h1>木蘭辭擬古決絕詞柬友</h1>
- <p>人生若只如初見,何事秋風悲畫扇。</p>
- <p>等閒變卻故人心,卻道故人心易變。</p>
- <p>骊山語罷清宵半,淚雨霖鈴終不怨。</p>
- <p>何如薄幸錦衣郎,比翼連枝當日願。</p>
- </center>
- </body>
- </html>
運行結果:
解決方法:為其指定中文字符集,<html>前加入
- <%@ page contentType="text/html;charset=gb2312" %>
實例二、JSP頁面傳遞中文參數時
注冊頁面:
- <%@ page contentType="text/html;charset=gb2312" %>
- <html>
- <head>
- <title>中文亂碼——JSP頁面傳遞中文參數時</title>
- </head>
- <body>
- <h2>申請賬號:</h2>
- <form action="userMsg.jsp" method="POST">
- <p>郵箱: <input type="text"name="email" id="email"/><p/>
- <p>昵稱: <input type="text"name="nickname" id="nickname"/><p/>
- &n
bsp; <p>密碼: <input type="password"name="password" id="password"/><p/>
個人信息頁面:
- <%@ page contentType="text/html;charset=gb2312" %>
- <html>
- <head>
- <title>中文亂碼——JSP頁面傳遞中文參數時 </title>
- </head>
- <body>
- <center>
- <h2>用戶信息:</h2>
- <% String email = request.getParameter("email"); %>
- <% String nickname = request.getParameter("nickname"); %>
- <% String password = request.getParameter("password"); %>
- <% String sex = request.getParameter("sex"); %>
- <% String introduction = request.getParameter("introduction");%>
- <p>郵箱: <
;% out.print(email); %><p/>
運行結果:
解決方法:修改個人信息頁面如下
- <%@ page contentType="text/html;charset=gb2312" %>
- <html>
- <head>
- <title>中文亂碼——JSP頁面傳遞中文參數時 </title>
- </head>
- <body>
- <h2>用戶信息:</h2>
- <% String email = newString(request.getParameter("email").getBytes("ISO-8859-1"), "gb2312");%>
- <% String nickname = newString(request.getParameter("nickname").getBytes("ISO-8859-1"), "gb2312");%>
- <% String password = newString(request.getParameter("password").getBytes("ISO-8859-1"), "gb2312");%>
- <% String sex = newString(request.getParameter("sex").getBytes("ISO-8859-1"), "gb2312");;%>
- <% String introduction = newString(request.getParameter("introduction").getBytes("ISO-8859-1"), "gb2312");;%>
- <p>郵箱: <% out.print(email); %><p/>
- &
lt;p>昵稱: <% out.print(nickname); %><p/>
實例三、Servlet處理中文參數時
注冊頁面:
- <%@ page contentType="text/html;charset=gb2312" %>
- <%@ page import="test.UserMsg"%>
- <html>
- <head>
- <title>中文亂碼——JSP頁面傳遞中文參數時</title>
- </head>
- <body>
- <h2>申請賬號:</h2>
- <form action="./UserMsg" method="POST">
- <p>郵箱: <input type="text"name="email" id="email"/><p/>
- <p>昵稱: <input type="text"name="nickname" id="nickname"/><p/>
- <p>密碼: <input type="password"name="password" id="password"/><p/>
- <p>性別: <input type="radio"name="sex" id="sex"value="男" /> 男
- <input type="radio" name="sex"id="sex" value="女" /> 女<p/>
- <textarea name="introduction"id="introduction" rows="5" cols="27">一句話介紹自己...</textarea>
- <p><input type="submit"value="提交申請"></p>
- &nb
sp; </form>
UserMsg.java(Servlet)
- package test;
- importjava.io.IOException;
- importjava.io.PrintWriter;
- importjava.io.UnsupportedEncodingException;
- importjavax.servlet.http.HttpServlet;
- importjavax.servlet.http.HttpServletRequest;
- importjavax.servlet.http.HttpServletResponse;
- public classUserMsg extends HttpServlet{
- public void doGet(HttpServletRequestrequest,
- HttpServletResponse response){
- doPost(request, response);
- }
- public void doPost(HttpServletRequestrequest,
- HttpServletResponse response){
- try {
- request.setCharacterEncoding("gb2312");
- } catch (UnsupportedEncodingExceptione) {
- e.printStackTrace();
- }
- PrintWriter out = null;
- try {
- out = response.getWriter();
- } catch (IOException e1) {
- e1.printStackTrace();
- }
- out.print("<html>");
- &nbs
p; out.print("<body>");
運行結果:
解決方法:在doPost中加入:
- response.setContentType("text/html; charset=gb2312");
