Jstl dynamically adds drop-down list items in jsp

Before using the jsp below, you need to write an Stu class to generate the set and get methods.

Public Class Stu{    private int id;    private String name;    public void setId(int id){       this.id=id;    }    public int getId(){       return this.id;    }    public void setName(String name){       this.name=name;    }    public String getName(){       return this.name;    }}

Write a simple servlet

public class gotoMall extends HttpServlet {public void doGet(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException {ArrayList<Stu> stus=new ArrayList<Stu>();Stu stu1=new Stu();stu1.setId(1);stu1.setName("aa");stu2.setId(2);stu2.setName("bb");stus.add(stu1);stus.add(stu2);request.setAttribute("stus", stus);request.getRequestDispatcher("/WEB-INF/admin/my.jsp").forward(request, response);}public void doPost(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException {this.doGet(request, response);}}

My. jsp
