Class JsonMapFlattener

java.lang.Object

org.springframework.vault.support.JsonMapFlattener

public abstract class JsonMapFlattener
extends Object

Flattens a hierarchical Map of objects into a property Map.

Flattening is particularly useful when representing a JSON object as Properties

JsonMapFlattener flattens maps containing nested List, Map and simple values into a flat representation. The hierarchical structure is reflected in properties using dot-notation. Nested maps are considered as sub-documents.

Input:

     {"key": {"nested: 1}, "another.key": ["one", "two"] }
 

Result

  key.nested=1
  another.key[0]=one
  another.key[1]=two
