How Can I Configure Jackson to Use Only Fields for JSON Serialization and Deserialization?

Configuring Jackson to Use Only Fields: A Comprehensive Solution

When serializing and deserializing objects to JSON, Jackson by default utilizes both getters/setters (properties) and fields. However, sometimes you may prefer to rely solely on fields for this process. Here's how you can achieve this:

On an individual class level, you can control the behavior using the @JsonAutoDetect annotation, as mentioned in the question. For a global configuration, you can customize the ObjectMapper as follows:

ObjectMapper mapper = new ObjectMapper();
mapper.setVisibility(
    mapper.getSerializationConfig().getDefaultVisibilityChecker()
            .withFieldVisibility(JsonAutoDetect.Visibility.ANY)
            .withGetterVisibility(JsonAutoDetect.Visibility.NONE)
            .withSetterVisibility(JsonAutoDetect.Visibility.NONE)
            .withCreatorVisibility(JsonAutoDetect.Visibility.NONE)
);

If you require global access to a configured mapper, consider using a wrapper class for a centralized approach to configuration.
