I.E

server.port=1234

TO

{
         


        

Answer 1

Personally I used this dependency:

  com.fasterxml.jackson.dataformat
  jackson-dataformat-properties 
  2.10.2
  compile

private static JavaPropsMapper javaPropsMapper = JavaPropsMapper.builder().build();
final JsonNode request = javaPropsMapper.readPropertiesAs(parameters, JsonNode.class);

Try to use schema validation to avoid possible issues in you mapping.

Although, with a simple object mapper it is possible also

Properties properties = new Properties();
properties.put("array", new int[] {1,2,3});
ObjectMapper objectMapper = new ObjectMapper();
objectMapper.writeValueAsString(parameters);

Output

{"fullname":["Foo","Bar"]}
