Question

我正在进行批量更新，如下所示。

List<String> memberGuids = (List<String>) newMembers.stream().map(Member::getGuid).collect(Collectors.toList());        
Session session = super.getEntityManager().unwrap(Session.class);
session.beginTransaction();
ScrollableResults members = session.getNamedQuery("Member.getMembersByGuid").setParameterList("memberGuids", memberGuids).setCacheMode(CacheMode.IGNORE).scroll(ScrollMode.FORWARD_ONLY);

int count = 0;
while (members.next()) {
    Member member = (Member) members.get(0);
    updateMember(member, newMembers.get(count));
    if (++count % JDBC_BATCH_SIZE == 0) {
        session.flush();
        session.clear();
    }
}

session.getTransaction().commit();
session.close();

我正在获取数据库中的更新值，但获得：

`java.lang.IllegalStateException：事务未激活。

如果我注释掉以下代码，

//session.beginTransaction();
//session.getTransaction().commit();

我收到以下错误。

我发现了问题。我在我的函数上使用@Transactional并在事务正在执行的函数内使用commit。所以我注释掉了以下代码并且我工作了。

//session.beginTransaction();
//session.getTransaction().commit();
//session.close();

java.lang.IllegalStateException：事务处于非活动状态
