Spring Security Access denied 403 after post

Question

I've tried almost everything in the others posts about it, nothing is related with my problem.

If I try to recover my URL via GET (ex: path/users/edit/1 ) everything works fine and I get redirected to the user edit page, but If I try to access this page via POST, the spring security deny my access to the page.

Both of the methods are mapped in my controller class.

@RequestMapping(value="/users/edit/{id}", method={RequestMethod.POST,RequestMethod.GET})
public ModelAndView login(ModelAndView model, @PathVariable("id") int id ) {
    model.addObject("user", this.userService.getUserById(id));
    model.setViewName("/users/add"); //add.jsp
    return model;
}

My form which I use post

<f:form method="post" action="/users/edit/${user.id}">
     <button type="submit">Edit</button>
</f:form>

Spring security.xml

Solution

I noticed you're using csrf protection, which by default protects any HTTP verb that modifies a resource (e.g. PUT, POST, DELETE,...). If you're using Spring's form tag, a csrf token should be automatically included as a hidden input in your form. You should check the source in your browser to verify the csrf token is there, otherwise you'll need something like this:

<input type="hidden"
    name="${_csrf.parameterName}"
    value="${_csrf.token}"/> 

You can read more about csrf protection/configuration in Spring reference.

That's it! Thank you!

If you are using Thymeleaf with Spring Boot, this manual way is only needed on login template. There is automatic way how to add CSRF token with th:action: <form action="#" th:action="@{/ingredients}" th:object="${ingredient}" method="post">
