POST responses not compressed despite Accept-Encoding Header being present in a request

I have encountered a strange case. I am working with a Spring Boot application which consists of a few different services.

For each service, in a application.properties file, those properties were added:

server.compression.enabled=true
server.compression.mime-types=application/json,application/xml,text/html,text/xml,text/plain,application/javascript,text/css
server.compression.min-response-size=1024

Now, it should work that every appropriate request contains "Accept-Encoding" header and response contains "Content-Encoding" header, and the response should be compressed.

It it almost works like that, but for one service POST responses do not contain "Content-Encoding", even though POST requests contain "Accept-Encoding". Such responses are not compressed, so it's not only about missing headers. GET responses/requests for this service work fine. Both GET/POST requests/responses for the rest of services work fine too.

This particular service's Spring Boot version is 1.5.16.RELEASE.

Where should I look for the cause? Can this setting be overwritten somehow for POST responses only?

Update: I also noticed that in POST responses for this service, "Vary: Accept-Encoding" header is missing. It's present in all other cases.

Try to change wiremock dependency configuration from compile to testCompile. In my case, wiremock in 2.22.0 version (with compile) caused this issue.
