Deprecation Removals

Most of deprecations from previous versions have been removed. It is strongly recommended to move to the replacing API. See JavaDocs for the deprecated API to determine what it is replaced in favor of.

MongoDb Driver 4.0

The spring-integration-mongodb provides now Reactive Streams channel adapter implementations based on the mongodb-driver-reactivestreams. For better end-user experience both sync and reactive drivers are optional dependencies in the spring-integration-mongodb. So, now you have to specify driver explicitly in your project:

implementation "org.springframework.integration:spring-integration-mongodb"
implementation "org.mongodb:mongodb-driver-reactivestreams"
// implementation "org.mongodb:mongodb-driver-sync"

FileSplitter JSON

The FileSplitter doesn't require a JSON processor (e.g. Jackson) presence in the classpath any more. It uses now a SimpleJsonSerializer for its FileMarker serialization when a markersJson is configured.
