我的网络应用程序的某个地方有问题，但我找不到解决方案。我遇到了一个循环僵局，它们总是发生在 2 个豆子上。他们使用的资源虽然不在这两个 bean 之间共享。如果不是用 Weld 注入的一个 bean，我就找不到连接。
在堆栈跟踪中，我可以看到锁是由 Weld 处理的，但我不知道它试图（再次）锁定的锁定资源。
应用程序的主包是com.cmp.webapp。
com.cmp.webapp.PointOfSalesBean，这是两个故障点之一，被注释掉了@javax.enterprise.context.ConversationBean。
com.cmp.webapp.GeoManager是@javax.enterprise.context.SessionScoped。
com.cmp.webapp.service.KernelService注入两个 bean 的范围也设置为 Session 。
锁定的线程之一报告了这一点：
