From the first look to your code , I notice that your request method not specified. At this case (When using @ModelAttribute) you have to make it as (POST) request.

@RequestMapping(value = "/insert", method = RequestMethod.POST)
@RequestMapping(value = "/accinsert" , method = RequestMethod.POST)

Why ? because actually your object will be retrieved due to Form Submission which is treated as POST request. Try that thing and check the results. If the problem is still maybe you have some real problem in your Presentation Layer (e.g JSP Page) that is responsible about submitting the data.

Good Luck !
