Aadam :
It might be hard to explain why, but I have this situation where I need to get the request url mapping string of currently requested url.
Like if I have a GET URL as "/Test/x/{number}"
I want to get "/Test/x/{number}" not "/Test/x/1"
can I get the actual declared url string in interceptor?
If this is possible how can I achieve this
Darren Forsythe :
You can implement a HanderInterceptor
to intercept, pre or post, request and introspect the method being called.
public class LoggingMethodInterceptor implements HandlerInterceptor {
Logger log = LoggerFactory.getLogger(LoggingMethodInterceptor.class);
@Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
HandlerMethod method = (HandlerMethod) handler;
GetMapping mapping = method.getMethodAnnotation(GetMapping.class);
log.info("URL is {}", Arrays.toString(mapping.value()));
return true;
}
}
This will output, URL is [/hello/{placeholder}]
Full example can be found here, https://github.com/Flaw101/spring-method-interceptor
You could add more logic to introspect only certain methods, certain types of requests etc. etc.
