 # FasterXML Jackson Examples
 
 This project demonstrates various FasterXML Jackson annotations in a Spring Boot application. It showcases common JSON

     - Demonstrates how to control which fields are included in JSON output
     - Example shows excluding null fields from the response

+    - Example demonstrates formatting dates with specific patterns and timezones

+    - Demonstrates how to flatten nested objects during serialization
+    - Example shows unwrapping an `Address` object into the main JSON structure

+7. **@JsonAnyGetter and @JsonAnySetter** (`/json-any-getter-setter`)
