Answer 1

With Spring Boot you can achieve this by registering new Module.

@Configuration
public class AppConfig {

    @Bean
    public Module module() {
        SimpleModule module = new SimpleModule("Module", new Version(1, 0, 0, null, null, null));
        module.addSerializer(LocalDateTime.class, new LocalDateTimeSerializer());
        module.addDeserializer(LocalDateTime.class, new LocalDateTimeDeserializer());

        return module;
    }
}

As stated in documentation here

Jackson 1.7 added ability to register serializers and deserializes via Module interface. This is the recommended way to add custom serializers -- all serializers are considered "generic", in that they are used for subtypes unless more specific binding is found.

and here:

Any beans of type com.fasterxml.jackson.databind.Module are automatically registered with the auto-configured Jackson2ObjectMapperBuilder and are applied to any ObjectMapper instances that it creates. This provides a global mechanism for contributing custom modules when you add new features to your application.
