HomeWork <学生作业提交管理系统> 这是一个朋友做的一个学生作业提交系统,也是做为毕业设计而完成的. 使用JSP,Servelet技术,很好的实现了MVC设计模式,现在拿出来,

package work.ctrol.ctrolStu;
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import java.util.*;
import work.info.WorkInfo;
import work.tools.SysTime;
public class ShowAllWork extends HttpServlet {
    private static final String CONTENT_TYPE = "text/html; charset=GB2312";

    //Initialize global variables
    public void init() throws ServletException {
    }

    //Process the HTTP Get request
    public void doGet(HttpServletRequest request, HttpServletResponse response) throws
            ServletException, IOException {
        response.setContentType(CONTENT_TYPE);
        PrintWriter out = response.getWriter();

        WorkInfo work=new WorkInfo();
        HttpSession session=request.getSession();
       String stuid= (String) session.getAttribute("stuNo");
       int stuNo=Integer.parseInt(stuid);
        ArrayList list=work.getAllwork(stuNo);
        if(list==null){
            out.println(work.getStatus());
        }
        session.setAttribute("allwork",list);
        request.setAttribute("welcome",SysTime.getWelcome());
        getServletContext().getRequestDispatcher("/student/index.jsp").forward(request,response);
        out.close();
    }

    //Process the HTTP Post request
    public void doPost(HttpServletRequest request, HttpServletResponse response) throws
            ServletException, IOException {
        doGet(request, response);
    }

    //Clean up resources
    public void destroy() {
    }
}
