java - 无法部署“中心图像 ID：一些/中心：最新”：java.lang.NullPointerException

Question

我使用 docker 通过 IntelliJ IDEA 运行我的 Spring Boot 应用程序。我可以构建我的应用程序的映像，但是，如果我运行我的映像，我将收到如下消息：

Failed to deploy 'centre Image id: some/centre:latest': java.lang.NullPointerException

几天前，我可以使用相同的操作来运行我的 docker 镜像，这只是一个单一的 spring-boot 应用程序。现在，我使用 maven 构建我的项目，所以，那个单一的应用程序是我项目的一个模块。之后，我遇到了问题。

我的相关文件如下：

码头文件：

EXPOSE 80 443
ENTRYPOINT [ "java", "-jar", "/app.jar" ]
