一個關于javaBean+servlet+jsp的MVC架構問題

//jsp的代碼：

//JavaBean代碼

package xx;

public class JiamiBean {

private String mingwen;

//private String key="";

public JiamiBean(){}

public JiamiBean(String mingwen){

this.mingwen=mingwen;

}

public void setMingwen(String mingwen){

this.mingwen=mingwen;

}

public String getMingwen(){

return mingwen;

}

}

//servlet代碼

package xx;

import java.io.IOException;

import java.io.PrintWriter;

import javax.servlet.RequestDispatcher;

import javax.servlet.ServletException;

import javax.servlet.http.HttpServlet;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

public class Jiami extends HttpServlet {

public Jiami() {

super();

}

public void doGet(HttpServletRequest request, HttpServletResponse response)

throws ServletException, IOException {

doPost(request,response);

}

public void doPost(HttpServletRequest request, HttpServletResponse response)

throws ServletException, IOException {

request.setCharacterEncoding("gb2312");

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

String mingWen=request.getParameter("mingwen");

JiamiBean jb=new JiamiBean(mingWen);

request.setAttribute("JiamiBean", jb);

RequestDispatcher rd=request.getRequestDispatcher("showMiwen.jsp");

rd.forward(request, response);

}

}
