For comparing reference objects like Integer, you should use Integer::compare
<code>
        System.out.println(list.stream().max((a, b) -> Integer.compare(a, b)).get()); //10
        System.out.println(list.stream().min((a, b) -> Integer.compare(a, b)).get());  //2

Yes, you can use MDC for it. But, it is better to add this logic in a filter, because logging is a cross-cutting concern. The logic in controller should be about querying model, and updating the view.

You need to use service for that. Create a service, and specify it as a provider in your angular components. This service will make REST calls to the backend, and fetch data, which will be used by the components.
