How can a mapped object with nested objects be updated using the Jackson Parser?

edit

To update a nested object of a mapped object using Jackson Parser, you can follow these steps:

1. Convert the mapped object to a JSON string using the Jackson ObjectMapper.

ObjectMapper objectMapper = new ObjectMapper();
String jsonString = objectMapper.writeValueAsString(mappedObject);

1. Parse the JSON string to a JsonNode using the Jackson ObjectMapper.

JsonNode jsonNode = objectMapper.readTree(jsonString);

1. Update the nested object in the JsonNode using its path.

ObjectNode nestedObjectNode = (ObjectNode) jsonNode.path("nestedObject");
nestedObjectNode.put("property", "newValue");

1. Convert the updated JsonNode back to a JSON string.

String updatedJsonString = objectMapper.writeValueAsString(jsonNode);

1. Convert the updated JSON string to the desired mapped object type.

MappedObjectType updatedMappedObject = objectMapper.readValue(updatedJsonString, MappedObjectType.class);

Note: Replace "nestedObject" and "property" with the actual names of the nested object and its property that you want to update.
