<%@ 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>

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>"); } }
