JSP开发应用是,中文乱码是个比较常见的问题,其根源是:Web容器默认的字符处理编码是ISO-8859-1。

实例一、JSP页面显示时

<html>

<head>

<title>中文乱码——JSP页面显示时</title>

</head>

<body>

<center>

<br/>

<h1>木兰辞拟古决绝词柬友</h1>

<p>人生若只如初见,何事秋风悲画扇。</p>

<p>等闲变却故人心,却道故人心易变。</p>

<p>骊山语罢清宵半,泪雨霖铃终不怨。</p>

<p>何如薄幸锦衣郎,比翼连枝当日愿。</p>

</center>

</body>

</html>

运行结果:

解决方法:为其指定中文字符集,<html>前加入

<%@ page contentType="text/html;charset=gb2312" %>

实例二、JSP页面传递中文参数时

注册页面:

<%@ page contentType="text/html;charset=gb2312" %>

<html>

<head>

<title>中文乱码——JSP页面传递中文参数时</title>

</head>

<body>

<h2>申请账号:</h2>

<form action="userMsg.jsp" method="POST">

<p>邮箱: <input type="text"name="email" id="email"/><p/>

<p>昵称: <input type="text"name="nickname" id="nickname"/><p/>

&n

bsp;<p>密码: <input type="password"name="password" id="password"/><p/>

<p>性别: <input type="radio"name="sex" id="sex"value="男" /> 男

<input type="radio" name="sex"id="sex" value="女" /> 女<p/>

<textareaname="introduction"id="introduction" rows="5" cols="27">一句话介绍自己...</textarea>

<p><input type="submit"value="提交申请"></p>

</form>

</body>

</html>

个人信息页面:

<%@ page contentType="text/html;charset=gb2312" %>

<html>

<head>

<title>中文乱码——JSP页面传递中文参数时 </title>

</head>

<body>

<center>

<h2>用户信息:</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>邮箱: <

;% out.print(email); %><p/>

<p>昵称: <% out.print(nickname); %><p/>

<p>密码: <% out.print(password); %><p/>

<p>性别: <% out.print(sex); %><p/>

<p>个人介绍:<%out.print(introduction); %></p>

</center>

</body>

</html>

运行结果:

解决方法:修改个人信息页面如下

<%@ page contentType="text/html;charset=gb2312" %>

<html>

<head>

<title>中文乱码——JSP页面传递中文参数时 </title>

</head>

<body>

<h2>用户信息:</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>邮箱: <% out.print(email); %><p/>

&

lt;p>昵称: <% out.print(nickname); %><p/>

<p>密码: <% out.print(password); %><p/>

<p>性别: <% out.print(sex); %><p/>

<p>个人介绍:<%out.print(introduction); %></p>

</body>

</html>

实例三、Servlet处理中文参数时

注册页面:

<%@ page contentType="text/html;charset=gb2312" %>

<%@ page import="test.UserMsg"%>

<html>

<head>

<title>中文乱码——JSP页面传递中文参数时</title>

</head>

<body>

<h2>申请账号:</h2>

<form action="./UserMsg" method="POST">

<p>邮箱: <input type="text"name="email" id="email"/><p/>

<p>昵称: <input type="text"name="nickname" id="nickname"/><p/>

<p>密码: <input type="password"name="password" id="password"/><p/>

<p>性别: <input type="radio"name="sex" id="sex"value="男" /> 男

<input type="radio" name="sex"id="sex" value="女" /> 女<p/>

<textareaname="introduction"id="introduction" rows="5" cols="27">一句话介绍自己...</textarea>

<p><input type="submit"value="提交申请"></p>

&nb

sp; </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>");

&nbs

p;out.print("<body>");

out.print("<h2>" +"用户信息:"+ "</h2>");

out.print("<p>"+"邮箱:"+request.getParameter("email")+"<p/>");

out.print("<p>"+"昵称:"+request.getParameter("nickname")+"<p/>");

out.print("<p>"+"密码:"+request.getParameter("password")+"<p/>");

out.print("<p>"+"性别:"+request.getParameter("sex")+"<p/>");

out.print("<p>"+"个人介绍:"+request.getParameter("introduction")+"<p/>");

out.print("</html>");

out.print("</body>");

}

}

运行结果:

解决方法:在doPost中加入:

response.setContentType("text/html; charset=gb2312");
