我正在将我的应用程序从 JBoss 7 迁移到 WildFly(v9.0.1),但由于 bean 事务管理错误,它无法部署。

以下是EventServiceImpl类的内容。
@Stateless
@Remote(EventService.class)
@TransactionAttribute(TransactionAttributeType.REQUIRED)
public class EventServiceImpl implements EventService {
/**
* Logger
*/
private static Logger log = LoggerFactory.getLogger(EventService.class);
private EventTableDAO eventDao;
@PersistenceContext(unitName = "SOMF-GT")
private EntityManager entityManager;
@Resource
private UserTransaction transaction;
public List<Map> loadEvents() throws EventsException {
Configuration configurationEntry = new Configuration();
try {
Map configuration = configurationService.getConfiguration();
if (configuration != null) {
eventDao = new EventTableDAO(Event.class, entityManager, transaction);
List<Map> eventsMapList = new ArrayList();
}
}
我知道如果我将事务管理更改为BMT,并使用@TransactionManagement(TransactionManagementType.BEAN),则会出现以下错误
WFLYJPA0060:需要事务才能执行此操作(使用事务或扩展持久性上下文)
我想知道为什么我们首先要更改这个?
有任何信息,请告诉我!
