有時我在啓動web服務器本身時遇到以下異常。無法弄清其發生的原因，是否與Spring或wildfly服務器有關？可能是導致此異常的原因是什麼？很少發生Spring MVC應用程序中的ConcurrentModificationException

你能分享你的context.xml？ – igreen
有20多個模塊（java和webapp）20 * 4 context.xml和context java config可用作EAR部署。如果你能告訴我你可能需要幫助我的配置的哪一部分，就像任何一個模塊的spring mvc配置一樣？我們使用locatorFactorySelector，parentContextKey來全局加載一些bean。 – Nick
好吧，所以它發生在加載上下文時，你的springBeans使用相同的列表。 – igreen
