我收到此错误:“EntityManager必须在事务中访问”对我来说有什么奇怪的,因为我的bean带有注释标记:
@Stateless(name = "UserControllerSession")
我已经注入了EntityManager:
@PersistenceContext(unitName = "app")
private EntityManager em;
这是我的方法:
@Override
@PermitAll
public String updateBlockedAndDeactivationReasonForIds(String userPk, String iban, List<String> associatedIds) {
UserLocal user = em.find(UserLocal.class, Long.valueOf(userPk));
if (user == null) {
return ("User with id: " + userPk + " does not exist ! \n");
}
user.setBlocked(true);
user.setActive(false);
user.setDeactivationReason(DeactivationReason.DEACTIVATION_MULTIPLY_IBAN_REASON);
user.setDeactivationDate(new Date());
StringBuilder message = new StringBuilder();
message.append(" IBAN " + iban + " is linked to multiple accounts: ");
for (String id : associatedIds) {
message.append(id + " ");
}
ContactJournalEntryBean cjb = new ContactJournalEntryBean("USER", user.getLogin(), new Date(), "Internet",
message.toString());
em.persist(user);
em.persist(cjb);
return "SUCCESS operation for user with id: " + userPk;
}
据我所知,EJB方法的默认值是Transactioanl.REQUIRED,因此应该创建defualt事务。另一个问题是,我可以在一次交易中持续2次吗?谢谢你的帮助
答案 0 :(得分:1)
我认为默认REQUIRED
仅适用于您实际使用@TransactionAttribute
注释的情况。尝试将其添加到您的方法(或类,如果您希望它作为所有方法的默认值)。
