Allow lastModified to be set for object (default to current time if not explicitly set)

@romangrebennikov Are there any plans to merge this?

[kevin-denver]

I would love to see this merged too because I'm currently stuck without this functionality

This repo has no activity since 2020. So assuming no one is going to merge this in, here's a reflection based walk-around I'm using, hope it helps:

import io.findify.s3mock.S3Mock;
import io.findify.s3mock.provider.InMemoryProvider;
import scala.collection.concurrent.TrieMap;

import java.lang.reflect.Field;
import java.util.Date;

public class YourTestClass {

    // ...

    private static Field bucketStoreField;
    static {
        try {
            bucketStoreField = InMemoryProvider.class.getDeclaredField("bucketDataStore");
            bucketStoreField.setAccessible(true);
        } catch (Exception e){
            throw new RuntimeException(e);
        }
    }

    public void setLastModified(String bucket, String key, Date lastModified) {
        InMemoryProvider p = (InMemoryProvider)s3mock.p();
        p.getObject(bucket, key).metadata().get().setLastModified(lastModified);
        // Hack to make listObject work
        TrieMap<String, InMemoryProvider.BucketContents> bucketStore =  (TrieMap<String, InMemoryProvider.BucketContents>)bucketStoreField.get(p);
        InMemoryProvider.BucketContents bucketContents = bucketStore.get(bucket).get();
        InMemoryProvider.KeyContents rawObject = bucketContents.keysInBucket().get(key).get();
        akka.http.scaladsl.model.DateTime newDateTime = (akka.http.scaladsl.model.DateTime)akka.http.scaladsl.model.DateTime.create(lastModified.getTime());
        bucketContents.keysInBucket().put(key, rawObject.copy(newDateTime, rawObject.data()));

    }
}
