我正在尝试从Hibernate 5.1.0迁移到5.2.1。 在应用程序启动期间，当我使用5.1.0时，有很多警告，我并不在意。警告如下：
DEBUG org.hibernate.jpa.spi.AbstractEntityManagerImpl [localhost-startStop-1] Mark transaction for rollback
我正在使用Spring 4.3.2和Tomcat 8.在Hibernate迁移到5.2.1之后，应用程序开始抛出大量异常。它们仅在启动时出现。一切正常。例外情况是：
DEBUG org.hibernate.resource.transaction.backend.jdbc.internal.JdbcResourceLocalTransactionCoordinatorImpl [localhost-startStop-1] JDBC transaction marked for rollback-only (exception provided for stack trace)

每个异常看起来都一样。 什么使这些例外被抛出？
