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。
