Comment configurer l'ObjectMapper pour ignorer les propriétés inconnues dans le JSON en Java

# Introduction

In Java development, working with JSON data is a common requirement. The ObjectMapper class from the Jackson library is a powerful tool for converting between Java objects and JSON. However, when processing JSON data, you may encounter properties that are not defined in your Java classes. This can cause exceptions during deserialization.

This lab will guide you through configuring the ObjectMapper to ignore unknown properties in JSON data. You will learn how to handle JSON gracefully, making your applications more robust when dealing with external data sources that may change over time.
