我在我的Wildfly 10应用服务器上配置了2个xa-datasources，并使用Hibernate ORM 5.2.9。数据库是Postgres 9.6。
在我的应用程序中，我有一个EJB，其中有2个嵌套的for循环，我必须在每个嵌套循环的迭代中从一个表中读取数据。但是过一段时间后，我遇到了这个异常：
javax.ejb.EJBTransactionRolledbackException: org.hibernate.HibernateException: Transaction was rolled back in a different thread!
我不明白为什么会发生这种情况。我有一个小的概念验证应用程序，它使用JDBC连接到数据库，一切都正常。
