Create basic form using spring 3 mvc framework

Question

I am new to Spring Framework . I am trying to create and submit a basic form, but I am not receiving a 404 error response from the second page.

MainController.java:

@RequestMapping(value = "/dangki", method = RequestMethod.GET)
public ModelAndView student() {
    return new ModelAndView("dangki", "command", new Student());
}

@RequestMapping(value = "/addStudent", method = RequestMethod.POST)
public String addStudent(@ModelAttribute("SpringFramework") Student myStudent,
        ModelMap model) {
    model.addAttribute("sinhvien", myStudent);
    return "ketqua";

}

Please rewrite this line into controller.

@RequestMapping(value = "/SpringFramework/addStudent", method = RequestMethod.POST)

Supposing that your controller definition is just like this:

@Controller
public class StudentController {

//... your code here
}

You have to change the form to post the data to the request mapping you declared, so:

<%@taglib uri="http://www.springframework.org/tags/form" prefix="form"%>
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>

    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title>Đăng kí</title>
    </head>
    <body>
        <h1>Đăng kí</h1>
        <form:form action="/addStudent/SpringFramework" method="POST">
            Tên:  <form:input type="text" path="name" value="sss"/> <br>
 ID: <form:input type="number" path="id" value="sss"/> <br>
 <input type="submit" value="Đăng kí">
 </form:form>
 </body>
</html>

By the way SpringFramework is a really poor choise for a variable name, I would use student for example.
