Thymeleaf Neither BindingResult nor plain target object for bean name 'person' available as request attribute

Question

From what I can tell this is set up correctly but I am getting the following error:

java.lang.IllegalStateException: Neither BindingResult nor plain target 
         


        

Answer 1

Model attribute has to be initialized (using GET method) before calling post method. In your case you need one more method in controller which does model.addAttribute("person",new Person()); and it has to be called before post.

Refer below link: https://spring.io/guides/gs/handling-form-submission/ OR http://forum.thymeleaf.org/Neither-BindingResult-nor-plain-target-object-for-bean-name-miniDoniie-available-as-request-attribute-td4027859.html

It has GetMapping as well as PostMapping in controller.
