html code:

Answer 1

The th:method="delete" creates the hidden input field automatically for you. If you add it manually as well you will have it twice. Check the source code.

I still got the POST Error message after the recommendations here. I found out Spring ignores those hidden fields by default. The solution is to activate it in your application.properties file:

spring.mvc.hiddenmethod.filter.enabled=true

My working code in my application looks like this:

Form:

    
        Delete
    

Controller:

@RequestMapping(value="/books/delete/{id}", method = RequestMethod.DELETE)
public String deleteBook(@PathVariable Long id) {
    bookService.deleteBook(id);
    return "books";
}
