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
