Various @RequestMapping
methods inside my @Controller
classes have custom annotations that I want to analyze at runtime.
E.g:
@Controller
@RequestMapping("/bla")
@RequireCommunityLevel("...")
@AnotherCustomAnnotation(value = "...")
public class FakeController {
// ...
@RequireScore(level = Score.Platinum, score = 8500)
@RequestMapping("/blabla")
@AnotherCustomAnnotation(value = "...")
public DTOResponse<MySpecialModel> getMySpecialModels() {
// ...
}
}
When I receive a request in my custom Interceptor
and Filter
classes, I want to analyze which Method
the request is going to call.
I have worked in the past with custom frameworks based on Javax Servlet
and Jetty
and often implemented some kind of method-registry one could interrogate.
For example:
public class CustomFilter extends Filter {
@Inject
private MyMethodRegistry registry;
@Override
public void doFilter(
ServletRequest request,
ServletResponse response,
FilterChain chain) throws IOException, ServletException {
// get the request path
final String path = getPath(request);
final Method m = this.registry.getMethodForPath(path);
// that's what I mean to do
if (m.getAnnotation(RequireScore.class) != null) { ... }
if (m.getDeclaringClass().getAnnotation(AnotherCustomAnnotation.class != null) { ... }
chain.doFilter(request, response);
}
}
I'm looking for a similar way in Spring
, possibly a built-in utility to analyze at runtime the Annotation
's on my @RequestMapping
methods. All of this should happen within my Interceptor/Filter.
