    The more I look at your example the more I think you should be calling version, not workingCopy. Working copies is a construct brought over from CMIS and is meant for use cases where you have a user that will want to edit their 'word doc' many times before versioning it. Your code suggests you dont want working copies. You just want to version

    so, workingCopy will create a record to locks table? and version will not? workingCopy will have long time locking? version will have short time locking?
    yes, I will do that , thanks
    Paul Warren
    @paulcwarren
    lock and unlock create the entries in the locks table. Both workingCopy and version will transfer the lock to the new entity in the version series.
    are you trying to do automatic versioning? because I recently added support to spring content for spring data envers

    @lmtoo
    I just want to have new version entity, and handle lock and unlock
    Paul Warren
    @paulcwarren
    K. Spring data envers will automatically create a new version of an entity whenever you save it. And with the support in spring-content it will do that for every setContent operation too. This is all done through save and setContent and because it is handled by hibernate removes the need for the pessimistic locking. It is more of an auditing thing but I mention it because it might be a better solution for you, depending on your use case.

    If that is of interest let me know as i need to document and cut a release to actually get it out there

    Hi @paulcwarren , I'm curious to know if its possible for renditions to process a collection of resources from a JPA content store? Have been testing renditions and it works really well but I have a use case where I'm looking to merge multiple related resources and render a single output.

    Hi @paulcwarren , when the @SuccessorId field be set, LockingAndVersioningRepository.version can't create new version from a nonleaf version?
    Paul Warren
    @paulcwarren
    That sounds right. We support a version series only at the moment. Not a version tree.
    Sounds like you need a version tree?
    乐哥
    @lmtoo
    yes , version tree
    workingCopy doesn't set @SuccessorId, I think I have to use this method
    If I don't have field annotated with @SuccessorId, Is version can replaced with workingCopy?
    Paul Warren
    @paulcwarren
    That's what it should do, yes. The idea is that the user creates a workingCopy that only they can see/edit and when they are ready (i.e. several days/edits later) they version that workingCopy and it becomes available to everyone.
    But it is a version series, not a tree I never intended workingCopy to be used as a version tree. I am not sure how you would do that actually. But if it works for you then great.

    I need to restore to history content when process is returned , and then create new version copy on that version
    Paul Warren
    @paulcwarren
    That should be what workingCopy does. The editor should get the workingCopy content. Everyone else should get the original content until it is versioned

    thanks.

    Hi @paulcwarren - Does Spring content has "store support" for "Google cloud storage" also? I can find examples for Amazon S3 only.

    Is it theoretically possible to place two store systems on classpath e.g. s3 and filesystem and based on the application property switch which one should be used ?

    I tried something like this:

    @ConditionalOnProperty(prefix = "springcontentdemo.storage", name = "type", havingValue = "filesystem")
    @EnableFilesystemStores("com.springcontentdemo.store")
    @Configuration
    public class FilesystemStorageConfig { ... }
    @ConditionalOnProperty(prefix = "springcontentdemo.storage.", name = "type", havingValue = "s3", matchIfMissing = true)
    @EnableS3Stores("com.springcontentdemo.store")
    @Configuration
    public class S3StorageConfig { ... }

    and i have spring-content-fs and spring-content-s3 as project dependencies and it is not working ... content store beans are not created ... it looks like FilesystemStoreRegistrar and S3StoresRegistrar are in conflict in case they both are on classpath.
    Even in case I remove one of these two spring config classes then it does not help ... it starts working only when I remove one of these two dependencies (s3 or fs) from project

    Is it ok that in DefaultS3StoreImpl#setContent(S, java.io.InputStream) method os variable is closed twice ? one using IOUtils.closeQuietly(os) and the second time in finally block os.close() ?
    problem is that this second closing of output stream sometimes (not sure when and why) causes that SimpleStorageResource.finishSimpleUpload() method is invoked again, so s3client is uploading file twice and the second try fails with this error:
    Caused by: com.amazonaws.SdkClientException: Unable to verify integrity of data upload. Client calculated content hash (contentMD5: FQeFaRaSLRVt4MnXW7KyWQ== in base 64) didn't match hash (etag: 5289df737df57326fcdd22597afb1fac in hex) calculated by Amazon S3.

    I can reproduce it very easily when I try to call setContent method twice with different stream, e.g. something like this:

            designPlanAttachmentStore.setContent(attachment, new ByteArrayInputStream(FILE_DATA));
            designPlanAttachmentStore.setContent(attachment2, new ByteArrayInputStream(FILE_DATA_2));

    the first setContent call is always successful (calling of os.close() in finally block does not trigger finishSimpleUpload()), but it always fails on the second setContent call as in this case os.close() in finally block trigger finishSimpleUpload()

    I'm not sure if problem is this os.close() in finally block or there is some issue in SimpleStorageResource

    Hello there, we are looking for a small CMS that allows us to manage news articles, videos and images. As we are a team of java developers, we have found this project. Is there an example that leads into that direction? I have found those: https://github.com/paulcwarren/spring-content-examples but I am lacking the overview/insights there :)

    Hi @paulcwarren,

    My organization is reviewing CMS frameworks. Do you have any updates on spring-content graduating to spring-projects in GitHub? I saw your post from 2018 (paulcwarren/spring-content#45). Also, do you have any names you can share about companies or groups currently using spring-content?

    Hi, Im getting this exception org.springframework.transaction.IllegalTransactionStateException: Pre-bound JDBC Connection found! JpaTransactionManager does not support running within DataSourceTransactionManager if told to manage the DataSource itself. It is recommended to use a single JpaTransactionManager for all transactions on a single DataSource, no matter whether JPA or JDBC access. after I setContent with jpa with postgres db. latest spring boot + content. This seem to happen when TM is accessed on same thread from different source. Its probably config issue on my side, but Im not very well versed. Any ideas?

    Hi Paul, I am having problems with S3ContentStore and aws-messaging dependencies.
    I am using S3ContentStore with no problems until I added the aws-messaging dependency to use amazon sqs service.

    Now, I can't start the app, this is the error at startup:
    Parameter 1 of constructor in internal.org.springframework.content.s3.config.S3StoreFactoryBean required a single bean, but 2 were found:

    - s3Client: defined by method 's3Client' in class path resource [internal/org/springframework/content/s3/boot/autoconfigure/S3ContentAutoConfiguration.class]
    - amazonS3: defined in null

    Without this dependency the application runs properly, any idea?
    I am using Spring Boot 2.4.5 and Spring Content 1.2.4
    Thanks!
