常見(jiàn)JSP中文亂碼例子及其解決方法
JSP開(kāi)發(fā)應(yīng)用是,中文亂碼是個(gè)比較常見(jiàn)的問(wèn)題,其根源是:Web容器默認(rèn)的字符處理編碼是ISO-8859-1。
實(shí)例一、JSP頁(yè)面顯示時(shí)
- <html>
- <head>
- <title>中文亂碼——JSP頁(yè)面顯示時(shí)</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(jiàn),何事秋風(fēng)悲畫(huà)扇。</p>
- <p>等閑變卻故人心,卻道故人心易變。</p>
- <p>驪山語(yǔ)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(dāng)日愿。</p>
- </center>
- </body>
- </html>
運(yùn)行結(jié)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(shí)例二、JSP頁(yè)面?zhèn)鬟f中文參數(shù)時(shí)
注冊(cè)頁(yè)面:
- <%@ page contentType="text/html;charset=gb2312" %>
- <html>
- <head>
- <title>中文亂碼——JSP頁(yè)面?zhèn)鬟f中文參數(shù)時(shí)</title>
- </head>
- <body>
- <h2>申請(qǐng)賬號(hào):</h2>
- <form action="userMsg.jsp" method="POST">
- <p>郵箱: <input type="text"name="email" id="email"/><p/>
- <p>昵稱(chēng): <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(huà)介紹自己...</textarea>
- <p><input type="submit"value="提交申請(qǐng)"></p>
- </form>
- </body>
- </html>
個(gè)人信息頁(yè)面:
- <%@ page contentType="text/html;charset=gb2312" %>
- <html>
- <head>
- <title>中文亂碼——JSP頁(yè)面?zhèn)鬟f中文參數(shù)時(shí) </title>
- </head>
- <body>
- <center>
- <h2>用戶(hù)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/>
- <p>昵稱(chēng): <% out.print(nickname); %><p/>
- <p>密碼: <% out.print(password); %><p/>
- <p>性別: <% out.print(sex); %><p/>
- <p>個(gè)人介紹:<%out.print(introduction); %></p>
- </center>
- </body>
- </html>
運(yùn)行結(jié)果:
解決方法:修改個(gè)人信息頁(yè)面如下
- <%@ page contentType="text/html;charset=gb2312" %>
- <html>
- <head>
- <title>中文亂碼——JSP頁(yè)面?zhèn)鬟f中文參數(shù)時(shí) </title>
- </head>
- <body>
- <h2>用戶(hù)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/>
- <p>昵稱(chēng): <% out.print(nickname); %><p/>
- <p>密碼: <% out.print(password); %><p/>
- <p>性別: <% out.print(sex); %><p/>
- <p>個(gè)人介紹:<%out.print(introduction); %></p>
- </body>
- </html>
實(shí)例三、Servlet處理中文參數(shù)時(shí)
注冊(cè)頁(yè)面:
- <%@ page contentType="text/html;charset=gb2312" %>
- <%@ page import="test.UserMsg"%>
- <html>
- <head>
- <title>中文亂碼——JSP頁(yè)面?zhèn)鬟f中文參數(shù)時(shí)</title>
- </head>
- <body>
- <h2>申請(qǐng)賬號(hào):</h2>
- <form action="./UserMsg" method="POST">
- <p>郵箱: <input type="text"name="email" id="email"/><p/>
- <p>昵稱(chēng): <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(huà)介紹自己...</textarea>
- <p><input type="submit"value="提交申請(qǐng)"></p>
- </form>
- </body>
- </html>
UserMsg.java(Servlet)
- package test;
- importjava.io.IOException;
- importjava.io.PrintWriter;
- importjava.io.UnsupportedEncodingException;

- importjavax.servlet.http.HttpServletRequest;
- importjavax.servlet.http.HttpServletResponse;
- public classUserMsg extends HttpServlet{

- 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>");
- out.print("<body>");
- out.print("<h2>" +"用戶(hù)信息:"+ "</h2>");
- out.print("<p>"+"郵箱:"+request.getParameter("email")+"<p/>");

- out.print("</html>");
- out.print("</body>");
- }
- }
運(yùn)行結(jié)果:
解決方法:在doPost中加入:
- response.setContentType("text/html; charset=gb2312");
