Question

I want to make a form in which I can update my entity in my REST application. For example I have a User entity whith username and realname fields.

Do I need in my request method do something like this

    @RequestMapping(value = "/admin/user/update", method = RequestMethod.POST)
public String updateHouse(@RequestBody String username, @RequestBody String realname, Model model) 

??

I would prefer to make something like this

@RequestMapping(value = "/admin/house/update", method = RequestMethod.POST)
public String updateHouse(@RequestBody User user, Model model) 

I mean that I want to send an object not every field. If i`ll have 20 fields in my entity I would have to add 20 params to my method. Thats not to fancy.

I`m using spring form tag

}

You don’t need @RequestBody here. Spring will automatically bind the form fields to the House class without it, i.e.

@RequestMapping(value = "/admin/house/update", method = RequestMethod.POST)
public String updateHouse(House house, Model model) {
