Class JsonIndexAccessor

java.lang.Object

org.springframework.integration.json.JsonIndexAccessor

All Implemented Interfaces:

IndexAccessor, TargetedAccessor

@Deprecated(forRemoval=true,
            since="7.0")
public class JsonIndexAccessor
extends Object
implements IndexAccessor

Deprecated, for removal: This API element is subject to removal in a future version.

Since 7.0 in favor of JacksonIndexAccessor for Jackson 3.

A SpEL IndexAccessor that knows how to read indexes from JSON arrays, using Jackson's ArrayNode API.

Supports indexes supplied as an integer literal — for example, myJsonArray[1]. Also supports negative indexes — for example, myJsonArray[-1] which equates to myJsonArray[myJsonArray.length - 1]. Furthermore, null is returned for any index that is out of bounds (see ArrayNode.get(int) for details).

Since:

6.4
