spring boot get controller class out of ServletRequest in a AuthorizationFilter

Question

Heee there,

right now I am totally stuck. I spend hours asking google but I haven't found any solution or approach yet. Maybe you guys can help me.

Some background information:

I am developing a microservice into an existing microservice infrastructure. I want to use spring boot and connect the service to our existing authentication service. There are plenty of other jax rs microservices which are already connected to it. I started with an authentication and an authorization filter. The authentication filter works perfectly.

The problem:

I want to use my own "Secured" annotation like in the other services. So there are some annotated resource methods in controllers like this example one:

    @Secured({Role.ADMIN,...})
    @RequestMapping(value = "/interfaces", method = RequestMethod.GET, produces = MediaType.APPLICATION_JSON_VALUE)
    public ResponseEntity<ExportInvoiceInterfaceResponseRepListWrapper> getAll() {
       ...
    } 

so when the following filter gets triggered I want to read the roles of the annotated controller method. In jax rs I just used the Class ResourceInfo to do so. As you may know I can't use this class in a default spring boot setup. Is there any way to get the class "the spring boot way"?

    public class AuthorizationFilter extends GenericFilterBean {
    @Context
    private ResourceInfo resourceInfo;

    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {

        HttpServletRequest httpRequest = (HttpServletRequest) request;
        HttpServletResponse httpResponse = (HttpServletResponse) response;

        // Get the resource class which matches with the requested URL
        // Extract the roles declared by it
        Class<?> resourceClass = resourceInfo.getResourceClass();
        List<Role> classRoles = extractRoles(resourceClass);
...

}

Any help would be awesome. Thank you in advanced.

Cheers Frank
