我有一个连接到使用MyBatis的两个数据源弹簧启动应用程序。春季启动在服务器启动时不加载,我已经检查了服务器启动过程中的日志,我没有看到任何弹簧引导它有关的消息。如开始在服务器启动后,WAS控制台显示应用程序的状态。
该应用程序无法正常工作,直到我重新启动它,并重新启动应用程序时,我可以看到在日志春季启动相关的消息。它重新启动后,该应用程序工作正常。
服务器版本:IBM WebSphere应用服务器网络部署(8.5.5.14)Java版本:8.0.2.10(IBM的WebSphere SDK Java技术版)

而且我设置使用servlet初始化活动的配置文件。
当我试图创建计划任务(在春季启动的应用程序是服务器),我已经注意到了相同的。这项工作并没有启动,直到我通过调用REST服务戳的应用程序或做其他事。不幸的是,我不知道该怎么办,使其工作。
