我目前在WildFly 25上的普通Java EE应用程序中遇到了一个奇怪的问题，我没有找到根本原因。我一直在为一些客户使用类似的配置，代码从未出现过任何问题。我知道要使事务工作，我需要正确地注入所涉及的一切。我使用@Stateless注解，并在需要它的方法上使用@Transactional注解。但是我从来没有遇到过这样的问题，我只是没有得到任何事务，而且我现在有点迷路了。数据源也是用JTA配置的，设置为true。
我的存储库：

@Stateless
public class DocumentImportLogRepository{
    
    @PersistenceContext(unitName = "AktenimportPU")
    EntityManager em;
    
    public <T> Object find(Class<T> entityClass, Object primaryKey)
    {
        return em.find(entityClass, primaryKey);
    }
    
    public void persist(Object object)
    {
        em.persist(object);
    }
    
    public void forcePersist(Object object)
    {
        em.persist(object);
        em.flush();
    }
    
    public void merge(Object object)
    {
        em.merge(object);
    }
    
    public void forceMerge(Object object)
    {
        em.merge(object);
        em.flush();
    }

    public void remove(Object object)
    {
        em.remove(object);
    }

在以下服务类中调用：

@Stateless
public class DocumentImportService 

[...]
    @Inject
    DocumentImportLogRepository importLogRepo;

来自几种方法，均源自：

@Transactional
public void doImport()
{
    [...]
    readInputFolder(Config.DOCUMENT_IMPORT_FOLDER);
    prepareImport(importLogRepo.getByState(State.PARSED), getPersonalakten());
    performArchive(importLogRepo.getByState(State.PREPARED));
    performArchiveMove(importLogRepo.getByState(State.ARCHIVED));
    [...]
}

其由控制器触发：

@Named("StartController")
@ApplicationScoped
public class StartController implements Serializable {

    
    @Inject
    private transient DocumentImportService importService;
    
    [...]
    
    @Transactional
    @TransactionTimeout(value=120, unit = TimeUnit.MINUTES)
    public void performTask(Task task)
    {
        [...]

            switch(task)
            {
                case Personalaktenimport:
                    importService.doImport();
                    break;
            }

        [...]
            
    }

实际方法调用失败：

@Transactional
public void readInputFolder(Path inputFolder) throws IOException
{
    [...] importLogRepo.forcePersist(entry); [...]
}

但有例外：
