java.lang.Object
com.ultikits.ultitools.utils.JsonPathUtil
public final class JsonPathUtil extends Object
JSON path utility class - replaces hutool-json's putByPath/getByPath functionality

Provides dot-separated path access and mutation of values inside a nested JSON Map. 

 Usage example:
 Map<String, Object> json = new LinkedHashMap<>();
 JsonPathUtil.putByPath(json, "a.b.c", "value");
 Object value = JsonPathUtil.getByPath(json, "a.b.c"); // "value"
