Spring Boot App在AWS上不起作用-Tomcat引發UnsatisfiedDependencyExceptions

Question

我有一台安靜的服務器，想部署在AWS虛擬機上。 該應用程序在我的本地tomcat上運行良好。 我可以從瀏覽器訪問tomcat的默認頁面和管理器應用程序，並且工作正常。 但是當我在tomcat上部署war文件時，它卻部署了

失敗-無法啟動上下文路徑/zift-0.0.1-SNAPSHOT上的應用程序

我檢查了catalina.out並意識到我主要得到了“ UnsatisfiedDependencyExceptions”，很奇怪，我自己的計算機上都沒有。 這是catalina.out：

當您說計算機上沒有問題時，是因為您正在STS的嵌入式tomcat中運行項目？ 因為如果是這種情況，則必須添加WebApplicationInitializer。
