java - How to pass ID to controller? -

i have form

<form method="post" action="/user/${id}">     <input type="text" name="id" value="${id}" placeholder="input id">     <button>get user</button> </form> 

how pass id controller?

    @requestmapping (value = "/user/{id}", method = requestmethod.post)     public string getstudent(@pathvariable ("id") integer id, model model){         user saveduser = userrepository.get(id);         model.addattribute("user", saveduser);         return "user";     } 

you way , consider passing ${id} value through query string

<a href="user?id=${id}">get user</a> 

and in controller,

@requestmapping ("user")     public string getstudent(@requestparam  integer id, model model){         user saveduser = userrepository.get(id);         model.addattribute("user", saveduser);         return "user";     } 

hope helps !
