我和我的团队第一次开发到Azure环境中。我们正在开发一个三层应用程序，我们的后端WebApp出现问题

此应用程序包含一个配置了Hibernate 5.0.3的DataLayer.jar，指向Jboss EAP 7.0数据源

我们的主要问题是，在部署1到2小时后（很明显，即使在长时间不用之后），我们开始收到如下错误：

如果我们禁用并重新启用部署的战争，它将恢复正常，直到前面提到的1/2小时

我们搜索了很多，但是对我们的项目做了很多修改，但是我们仍然有同样的问题

实际上，我们的Jboss EAP 7.0数据源配置如下：

提前感谢您的帮助

编辑：我们在Jboss上也升级了sqljdbc库模块，我们将最后一个sqljdbc42.jar替换为默认的。
当连接被终止时，这些错误为零。它们有时发生在大工作负载、连接闲置一段时间以及发生节流时。由于这种类型的错误以及Azure SQL数据库自然出现的一些暂时性错误，您应该将所有SQL命令包装在重试逻辑上。请在文章中了解有关暂时性错误和重试逻辑的更多信息
