public class CustomJackson2jsonEncoder
extends org.springframework.http.codec.json.Jackson2CodecSupport
implements org.springframework.http.codec.HttpMessageEncoder<Object>

Base class providing support methods for Jackson 2.9 encoding. For non-streaming use cases, Flux elements are collected into a List before serialization for performance reason.
