# 19.6 总结

* Spring 应用程序可以部署在许多不同的环境中，包括传统的应用程序服务器、CloudFoundry 等平台即服务（PaaS）环境，或作为Docker容器部署。
* 在构建WAR文件时，您应该包括一个子类 SpringBootServletInitializr 以确保 Spring 的 DispatcherServlet 配置正确。
* 构建为可执行 JAR 文件允许 Spring Boot 应用程序部署到多个云平台，而无需 WAR 文件。
* 容器化 Spring 应用程序就像使用用于 Maven 的 Dockerfile 插件一样简单。它将一个可执行的 JAR 文件包装在 Docker 容器中，该容器可以部署在任何可以部署 Docker 容器的地方，包括云提供商，如 Amazon Web Services、Microsoft Azure、Google Cloud Platform、Pivotal Web Services (PWS)、和关键容器服务（PKS）。
