Class JacksonPageDeserializer

java.lang.Object
tools.jackson.databind.ValueDeserializer<org.springframework.data.domain.Page<?>>
org.axonframework.extension.spring.data.JacksonPageDeserializer
All Implemented Interfaces:
tools.jackson.databind.deser.NullValueProvider
public class JacksonPageDeserializer extends tools.jackson.databind.ValueDeserializer<org.springframework.data.domain.Page<?>>
Custom Jackson deserializer for the Spring Data Page interface.

This deserializer converts JSON representations of paginated data into PageImpl instances. It extracts the content array, number (page number), size (page size), and totalElements from the JSON structure.

The deserializer handles missing fields gracefully by applying sensible defaults:

  • number defaults to 0
  • size defaults to the content size (minimum 1)
  • totalElements defaults to the content size
Since:
5.1.0
