You should not use Spring Data Neo4j R/X anymore. It was a WIP project that eventually finds its destination as the successor of Spring Data Neo4j 5.x (and before). With a recent Spring Boot release (starting with 2.4), you will get the completely rewritten Spring Data Neo4j if you add the Spring Data Neo4j Boot starter to your dependencies:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-neo4j</artifactId>
</dependency>
And yes, it has @CompositeProperties (https://docs.spring.io/spring-data/neo4j/docs/current/reference/html/#custom.conversions.composite-properties)
@Node
public class Entity {
// id etc.
@CompositeProperty
private Map<String, String> additionalFields = new HashMap<>();
}
It supports prefix, converter, and even converterRef(erences) to bean instances.
