JSON to JAVA

Convert JSON to Java Map<String,Object> or List<Map<String,Object>>

DEMO

Use cases

• When you need to save JSON to NoSQL each time and don't want to create class for it.

For example: you have Organization class and organization collection on MongoDB.

   String name;

And you are asked to add map information that organization could use. It is list of map configurations

One way to solve it:

Create class

   String name;
   List<MapInfo> maps;

For this you need to create class and keep collection on MongoDB. Too much for just keeping map info.

OR

Use Map<String,Object> or List<Map<String,Object>>>

   String name;
   List<Map<String,Object>> maps;

And you have following JSON to persist each time:

[ 
        {
            "default" : true,
            "imageUrl" : "/img/map/osm.png",
            "name" : "OSM",
            "type" : "Tile Layer",
            "url" : "https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png"
        }, 
        {
            "default" : false,
            "imageUrl" : "/img/map/yandexsat.png",
            "name" : "Yandex Sat",
            "type" : "Yandex Sat",
            "url" : ""
        }
]
