Posted a question in SO [0]. Question is:
I have a need to map standard Json array to a custom List type (infact not
java.util.List at all but javaslang.collection.List). Adding to the
complexity, we don't have static beans where we could define the list type
as javaslang type but we need to map to generic Map but the list instance
should be of type javaslang.collection.List.
I tried with creating new custom deserializer but since we are trying to
deser into generic Map, it is not touching that custom deserializer at all.
For ex., here is the test case we are looking to pass.
@Test@DisplayName("list instance is javaslang list")void listAsJsList() throws
Exception {
Map<String, Object> object = objectMapper.readValue(
"{\"records\": [{\"id\": \"123\"}, {\"id\": \"124\"} ] }",
HashMap.class);
assertThat(object.get("records")).isInstanceOf(javaslang.collection.List.class);}
Any help is appreciated.
