Question

I am using spring and Hibernate in my application,There is one scenario where i insert same records morethan once ,So application correctly throwing Constraint Exception because i applied Unique constraint in one of the db column.So far is everything fine.

But i have to display some custom message like “record already exists'” instead of showing Hibernate Exception.

How can i do with Spring framework.

Any hints or examples greatly appreciated.

Yes you can exception in controller:

  @ExceptionHandler(Exception.class)
      public ModelAndView handleMyException(Exception  exception) {
         ModelAndView mv = new ModelAndView("error");
         mv.addObject("message"."record already exists");
         return mv;
              } 

Of cause you can catch any tpe of exception just insert it as the parameter to @ExceptionHandler

Hope it helps.
