Hi,I got a problem when my spring-boot program running with native image. It can't serializer java.sql.Date caus class com.fasterxml.jackson.databind.ser.std.SqlDateSerializer not found.It only happend in native image.if my program don't running in native image,it works well.

Comment From: wilkinsona
Jackson loads a small number of its less commonly used serializers using reflection. Without some additional metadata, these serializers cannot be loaded in a native image. You could fix your problem by providing some reflection hints that allow SqlDateSerializer to be loaded and instantiated through reflection.
I'll transfer this issue to the Framework team as they may want to consider automatically adding the necessary reflection hints when org.springframework.aot.hint.annotation.RegisterReflectionForBindingProcessor detects that a java.sql.Date will be serialized and that Jackson's in use.

@wilkinsona THX!!! My problem was solved when I added the following configuration ```@Component @ImportRuntimeHints(SqlDateSerializerRuntimeHintsConfig.SqlDateSerializerRuntimeHints.class) public class SqlDateSerializerRuntimeHintsConfig {
static class SqlDateSerializerRuntimeHints implements RuntimeHintsRegistrar {
@Override
public void registerHints(RuntimeHints hints, ClassLoader classLoader) {
for (Constructor<?> constructor : SqlDateSerializer.class.getConstructors()) {
hints.reflection().registerConstructor(constructor,ExecutableMode.INVOKE);
}
}
}
} ```
I'll transfer this issue to the Framework team as they may want to consider automatically adding the necessary reflection hints when
org.springframework.aot.hint.annotation.RegisterReflectionForBindingProcessordetects that ajava.sql.Datewill be serialized and that Jackson's in use.That's great!!!
Comment From: sdeleuze
It could be interesting to explore if OptionalHandlerFactory can be used in BindingReflectionHintsRegistrar#registerJacksonHints (with proper classpath check) to support the various serializers/deserializers listed there.
Comment From: sdeleuze
After a deeper look, since those hints are not very dynamic and can take advantage of conditionalOnType, I think it will be better to support those on https://github.com/oracle/graalvm-reachability-metadata side. I will create a related PR that I will link in a comment.
