How can I send form values from jsp file to controller in Spring, JSP?
Question
I'm trying to design a web page allows users to make comments on eachothers' profiles. To do this, the logged in user clicks the name of another user and see his/her detailed profile page and can make comment on that page. So the Comment table has two foreign key columns as commentator_id and owner_id . When a user makes a comment on another user's profile, the comment table will keep the both users' id and the text, title of comment and so on.
Here's my Controller :
@RequestMapping(value = "/comment", method = RequestMethod.GET)
public ModelAndView comment(Principal principal, String username, @ModelAttribute Comment c) {
ModelAndView result = new ModelAndView("result");
User user = userService.findByUsername(username); // the user who gets the comment
String username2 = (String) ((Authentication) principal).getPrincipal(); //logged in user who makes the comment
User authenticatedUser = userService.findByUsername(username2);
c.setCommentator(authenticatedUser);;
c.setOwner(user);
user.getComments().add(c);
userService.save(host);
String message = "Com was successfully added.";
result.addObject("message", message);
return result;
}
My jsp file :
<body>
<form method="post" action="comment">
<center>
<table border="1" width="30%" cellpadding="5">
<thead>
<tr>
<th colspan="2">Leave a referance</th>
</tr>
</thead>
<tbody>
<tr>
<td>Title</td>
<td><input type="text" name="title" value="" /></td>
</tr>
<tr>
<td>Text</td>
<td><input type="text" name="message" value="" /></td>
</tr>
// ...
</tbody>
</table>
</center>
<a href="<c:url value="/comment"><c:param name="username" value="${user.getUsername()}"/></c:url>">Send</a>
</form>
</body>
With this way, a user can make comment on another user's profile but the Comment table only keeps the id of both user but not the text, title and other values which I get from the form. How can I also keep form values in the db?

use ModelAttribute annotation
public ModelAndView getMessage(@ModelAttribute("s") Student s){
ModelAndView model=new ModelAndView("Successpage");
return model;
}
