<input type="submit" value="提交">
<input type="reset" value="重置">
</center>
</td>
</tr>
</table>
</form>

步骤2、编写RegisterServlet

String UserName = req.getParameter("User_Name");
String UserPass = req.getParameter("User_Pass");
String UserSex  = req.getParameter("User_Sex");
String UserPresent = req.getParameter("User_Present");
String Userfavor[] = req.getParameterValues("User_Favor");

for (int i=0;i<Userfavor.length;i++){
Userfavor[i] = changChar(Userfavor[i]);
}
UserName = changChar(UserName);
UserPass = changChar(UserPass);
UserSex  = changChar(UserSex);
UserPresent = changChar(UserPresent);

resp.setContentType("text/html;charset=utf-8");
PrintWriter out = resp.getWriter();

out.write("<html> <body><center> <h1>");
out.write("姓名："+UserName+"<br>");
out.write("密码："+UserPass+"<br>");
out.write("性别："+UserSex+"<br>");

for (int i=0;i<Userfavor.length;i++){
out.write("爱好："+Userfavor[i]+"<br>");
}
out.write("个人介绍："+UserPresent+"<br>");
out.write("</h1></centen> </body> </html>");
out.flush();

<servlet>
<servlet-name>RegsiterServlet</servlet-name>
<servlet-class>com.java.servlet.RegsiterServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>RegsiterServlet</servlet-name>
