i want insert data database using angularjs , spring mvc, according tutorial did failed insert data database.

       @requestmapping(value = "/add", method = requestmethod.post)           public @responsebody string addemployee(@modelattribute(value="employee")employeeentity employee, bindingresult result)  {     employeemanager.addemployee(employee);     return "redirect:/"; }

you didn't specify problem , behaviour experiencing, there seems problems code can pointed out.

it seems trying mix 2 ways of communicating backend - more traditional, form based approach, , rest api.

annotating controller method @responsebody means, spring should not try resolve view render. should instead convert object has been returned method using message converter (usually - serialize json) , send result client in response body. used expose rest endpoint.

that means returning string "redirect:/" not cause redirect. instead string returned in body.

it better return persisted entity returned employeemanager.addemployee(employee) if process of persisting causes id set. way client can receive id , find employee later.

if passing data angular backend using json should use @requestbody annotation instead of @modelattribute. in turn cause object deserialized. did not show employeeentity class, don't know if want.

on client side don't need form element. angular can pass data using ajax calls. having form , submit button cause browser reload page , not want if creating single page application.
