### 55.1 Cloud Foundry 如果不指定其他打包方式，Cloud Foundry会启用它提供的默认打包方式。Cloud Foundry的[Java buildpack](https://github.com/cloudfoundry/java-buildpack)对Spring应用有出色的支持，包括Spring Boot。你可以部署独立的可执行jar应用，也可以部署传统的`.war`形式的应用。 一旦你构建应用（比如，使用`mvn clean package`）并[安装`cf`命令行工具](http://docs.cloudfoundry.org/devguide/installcf/install-go-cli.html)，你可以使用下面的`cf push`命令（将路径指向你编译后的`.jar`）来部署应用。在发布应用前，确保[你已登陆cf命令行客户端](http://docs.cloudfoundry.org/devguide/installcf/whats-new-v6.html#login)。 ```shell $ cf push acloudyspringtime -p target/demo-0.0.1-SNAPSHOT.jar ``` 查看[`cf push`文档](http://docs.cloudfoundry.org/devguide/installcf/whats-new-v6.html#push)获取更多可选项。如果相同目录下存在[manifest.yml](http://docs.cloudfoundry.org/devguide/deploy-apps/manifest.html)，Cloud Foundry会使用它。 就此，`cf`将开始上传你的应用： ```java Uploading acloudyspringtime...

OK name requested state instances memory disk urls ... acloudyspringtime started 1/1 512M 1G acloudyspringtime.cfapps.io ... ``` 一旦Cloud Foundry意识到你的应用已经部署，你就可以点击给定的应用URI，此处是[acloudyspringtime.cfapps.io/](http://acloudyspringtime.cfapps.io/)。
