阴影插件构建的多模块应用程序-由于缺少ServletWebServerFactory bean而无法启动ServletWebServerApplicationContext

Question

我有正在做一些业务人员的应用程序，并通过REST API呈现了结果。 构建的结果应该是一个可执行的jar，然后将其转换为dockerfile。

最近，我一直在尝试将其部分分成maven模块。 我已经拆分了应用程序（在IDE中构建和运行时效果很好），使用maven-shade-plugin组装了jar，但是当我尝试使用java -jar命令运行应用程序时，收到以下错误消息：

`org.springframework.context.ApplicationContextException：无法启动Web服务器。嵌套异常是org.springframework.context.ApplicationContextException：由于缺少ServletWebServerFactory bean而无法启动ServletWebServerApplicationContext。

我已经尝试过使用@EnableAutoConfiguration注释并使用SpringBootServletInitializer扩展主类-无效。

我将不胜感激。谢谢！
