Java 在一段非活动时间后，需要事务来执行此操作

我在停用一段时间后出现此错误，但当我再次登录时，一切都开始正常工作

这不是会话，因为我将其设置为30分钟，空闲时间约为5分钟。我收到此错误

有什么想法吗

UsuariManager.java

...
public Usuari save(Usuari usuari) {

    if (usuari.getId() == null) {
        this.em.persist(usuari);    <----line
        return usuari;
    } else {
        return this.em.merge(usuari);
    }
}
