常见3个例子及其解决方法如下
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/>
<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/>
<textarea name=\"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/>
<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/>
<textarea name=\"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>
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>\" +\"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\");
以上就是几种常见JSP中文乱码例子及其解决方法,希望能够帮助大家解决JSP中文乱码的问题。
