So when first I hit localhost:8080 then I am able to get index.html from there I click on the link to add order then I should get redirected to add-journeyFoodOrder.html view where I am getting the error(please view controller code that will give more clarity). Error logs are as:

Have you researched the root cause error mentioned in the stack trace you provided? "Caused by: java.lang.IllegalStateException: Neither BindingResult nor plain target object for bean name 'journeyFoodOrder' available as request attribute". There are several questions and answers on SO relating to this error. — andrewjames
Does this answer your question? What causes "java.lang.IllegalStateException: Neither BindingResult nor plain target object for bean name 'command' available as request attribute"? — andrewjames
I got it what you are saying but I was referring to this baeldung.com/spring-boot-crud-thymeleaf where they have not added it in signup method(and that code (github.com/eugenp/tutorials/tree/master/spring-boot-modules…) is working fine). — Shivam

You need to add the object which you reference in th:object:

 <form action="#" th:action="@{/addJourneyFoodOrder}" th:object="${journeyFoodOrder}" method="post">

I see that you mention it but there is no adding of this model attribute inside the GET mapping. Add this from your GET mapping and it should work just fine.

LE:

You can also use this variant:

@GetMapping("/signup") public String showSignUpForm(JourneyFoodOrder journeyFoodOrder) { return "add-journeyFoodOrder"; }
