Why does Finatra use flatMap and not just map?

Asked 2020-Dec-07 at 18:18

This might be a really dumb question but I am trying to understand the logic behind using #flatMap and not just #map in this method definition in Finatra's HttpClient definition:

From my understanding of FP, exceptions are not thrown. This would be, as you said, a side-effect. Exceptions are instead values that are handled at some point in the execution of the program.

Cats (and i'm sure other libraries, too) employs this technique too (https://github.com/typelevel/cats/blob/master/core/src/main/scala/cats/ApplicativeError.scala).

Therefore, the flatMap call allows the exception to be contained within a satisfied Future here and handled at a later point in the program's execution where other exception value handling may also occur.

how to set response with camelCase in finatra

Asked 2020-Apr-28 at 01:13

I need to return a json response in camelCase with finatra but it is in snake_case by default. From what I found so far, I need to use ObjectMapper, but I can't understand where do I pass it once I create it. An example would be very helpful. Here is what I have:

Set Finatra HTTP request timeout

Asked 2020-Jan-24 at 07:08

Is it possible to set HTTP request-response timeout in a Finatra server?

The http controller callback typically returns a Future, that once resolved the response is transmitted. I would like to define, within Finatra, how long the server should wait before returning a 500 or 400 response.

Your problem is that you're using equality in the first parameter and matcher for the second one. Try using matchers for all arguments.

But a bigger problem that I feel here is that you're trying to mock 3rd party library - this is something you should avoid. This would also solve your problem. Here's some extra read about it - TDD best practices: don't mock others

I recommend using nginx and its SSL Termination capability: https://docs.nginx.com/nginx/admin-guide/security-controls/terminating-ssl-http/

The nginx service should be the entry point to your application, where you terminate SSL using your provided cert/key then pass unencrypted traffic between your container apps over the overlay network.

It's a best practice to terminate SSL like this, and if you do want to encrypt network traffic within your cluster, then do so with separate certs from your ingress controller.

Generically Serialize Java Enums to json using json4s

Asked 2018-Jan-13 at 21:41

Our finatra application uses json4s to serialize objects to jsons in our controller responses. However, I noticed that when trying to serialize enums, it creates an empty object.

I don't think there is a clean solution because of the type-safety constraints. Still if you are OK with a hacky solution that relies on the fact that Java uses type erasure, here is one that seems to work:

I couldn't find the test class on github however the answer to this depends on what you want to achieve. You wouldn't mock a class however using specs2 and mockito you can spy on it to determine if something has happened this is an example of what you might be trying to achieve.
