2.修改具体的信息

2.1获取信息

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    request.setCharacterEncoding("utf-8");
    response.setContentType("text/html;charset=utf-8");

    int id= Integer.parseInt(request.getParameter("id"));
    String name= request.getParameter("name");
    String gender=request.getParameter("gender");
    String age=request.getParameter("age");
    String address= request.getParameter("address");
    String email=request.getParameter("email");

2.2建立的person对象，进行赋值

Person person=new Person();
person.setId(id);
person.setName(name);
person.setGender(gender);
person.setAge(Integer.parseInt(age));
person.setAddress(address);
person.setEmail(email);


personService.upDate(person);
response.getWriter().write("添加成功");
response.sendRedirect("/per_list");

然后用service进行业务方法的实现
