常見3個例子及其解決方案如下
執行個體一、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>等閑變卻故人心，卻道故人心易變。</p> <p>驪山語罷清宵半，淚雨霖鈴終不怨。</p> <p>何如薄倖錦衣郎，比翼連枝當日願。</p> </center> </body> </html>
運行結果：
解決方案：為其指定中文字元集，<html>前加入
<%@ page contentType="text/html;charset=gb2312" %>
執行個體二、JSP頁面傳遞中文參數時
註冊頁面：
<%@ 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>申請帳號：</h2> <form action="userMsg.jsp" method="POST"> <p>郵箱： <input type="text"name="email" id="email"/><p/> <p>暱稱： <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> </form> </body> </html>
個人資訊頁面：
<%@ 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>使用者資訊：</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>暱稱： <% out.print(nickname); %><p/> <p>密碼： <% out.print(password); %><p/> <p>性別： <% out.print(sex); %><p/> <p>個人介紹：<%out.print(introduction); %></p> </center> </body> </html>
運行結果：
解決方案：修改個人資訊頁面如下
<%@ 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>使用者資訊：</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>暱稱： <% out.print(nickname); %><p/> <p>密碼： <% out.print(password); %><p/> <p>性別： <% out.print(sex); %><p/> <p>個人介紹：<%out.print(introduction); %></p> </body> </html>
執行個體三、Servlet處理中文參數時
註冊頁面：
<%@ 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>申請帳號：</h2> <form action="./UserMsg" method="POST"> <p>郵箱： <input type="text"name="email" id="email"/><p/> <p>暱稱： <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> </form> </body> </html>
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>"); out.print("<body>"); out.print("<h2>" +"使用者資訊："+ "</h2>"); out.print("<p>"+"郵箱："+request.getParameter("email")+"<p/>"); out.print("<p>"+"暱稱："+request.getParameter("nickname")+"<p/>"); out.print("<p>"+"密碼："+request.getParameter("password")+"<p/>"); out.print("<p>"+"性別："+request.getParameter("sex")+"<p/>"); out.print("<p>"+"個人介紹："+request.getParameter("introduction")+"<p/>"); out.print("</html>"); out.print("</body>"); } }
運行結果：
解決方案：在doPost中加入：
response.setContentType("text/html; charset=gb2312");
