JsonMapper

If you only have simple use cases you can use avaje-json without avaje-jsonb.

For use cases that only want to map to the following types:

• String
• Boolean
• Integer
• Long
• Double
• Map<String, Object>
• List

  Create a JsonMapper

  static final JsonMapper mapper = JsonMapper.builder().build()

  Map example

  var map = Map.of("key", "some value", "otherKey", 42).

  String asJson = mapper.toJson(map);

  // read json into a Map Map<String,Object> asMap = mapper.fromJsonObject(asJson);

  List example

  var map0 = Map.of("key", "a", "otherKey", 42); var map1 = Map.of("key", "b", "otherKey", 99);

  var list = List.of(map0, map1).

  String asJson = mapper.toJson(list);

  // read json into a List List asList = mapper.fromJsonArray(asJson);
