Here is an example of how to use the IgnoredPropertyException class from the Jackson Databind library to handle the exception of an ignored property during deserialization:

import com.fasterxml.jackson.core.JsonParser;
import com.fasterxml.jackson.databind.DeserializationContext;
import com.fasterxml.jackson.databind.JsonDeserializer;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.exc.IgnoredPropertyException;

import java.io.IOException;

public class MyClassDeserializer extends JsonDeserializer<MyClass> {

    @Override
    public MyClass deserialize(JsonParser p, DeserializationContext ctxt) throws IOException {
        try {
            ObjectMapper mapper = (ObjectMapper) p.getCodec();
            MyClass myClass = mapper.readValue(p, MyClass.class);
            return myClass;
        } catch (IgnoredPropertyException e) {
            // handle the exception here
            System.out.println("Ignored property: " + e.getPropertyName());
            return null;
        }
    }
}

You can then use this custom deserializer by registering it with the ObjectMapper:

ObjectMapper mapper = new ObjectMapper();
SimpleModule module = new SimpleModule();
module.addDeserializer(MyClass.class, new MyClassDeserializer());
mapper.registerModule(module);

Then you can deserialize your JSON to MyClass as follow:

MyClass myClass = mapper.readValue(jsonString, MyClass.class);

Please note that the above example is just a skeleton code, you may need to handle the exception and add proper validation based on your use case.

The IgnoredPropertyException class is thrown when an ignored property is encountered during deserialization. The getPropertyName() method returns the name of the ignored property.

You can use this exception to handle the ignored properties during deserialization, you can log the property name, throw an exception or handle
