### 55.1 Cloud Foundry 如果不指定其他打包方式，Cloud Foundry會啟用它提供的默認打包方式。Cloud Foundry的[Java buildpack](https://github.com/cloudfoundry/java-buildpack)對Spring應用有出色的支持，包括Spring Boot。你可以部署獨立的可執行jar應用，也可以部署傳統的`.war`形式的應用。 一旦你構建應用（比如，使用`mvn clean package`）并[安裝`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（將路徑指向你編譯后的`.jar`）來部署應用。在發布應用前，確保[你已登陸cf命令行客戶端](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`文檔](http://docs.cloudfoundry.org/devguide/installcf/whats-new-v6.html#push)獲取更多可選項。如果相同目錄下存在[manifest.yml](http://docs.cloudfoundry.org/devguide/deploy-apps/manifest.html)，Cloud Foundry會使用它。 就此，`cf`將開始上傳你的應用： ```java Uploading acloudyspringtime... OK Preparing to start acloudyspringtime... OK -----> Downloaded app package (8.9M) -----> Java Buildpack source: system -----> Downloading Open JDK 1.7.0_51 from .../x86_64/openjdk-1.7.0_51.tar.gz (1.8s) Expanding Open JDK to .java-buildpack/open_jdk (1.2s) -----> Downloading Spring Auto Reconfiguration from 0.8.7 .../auto-reconfiguration-0.8.7.jar (0.1s) -----> Uploading droplet (44M) Checking status of app 'acloudyspringtime'... 0 of 1 instances running (1 starting) ... 0 of 1 instances running (1 down) ... 0 of 1 instances running (1 starting) ... 1 of 1 instances running (1 running) App started ``` 恭喜！應用現在處于運行狀態！ 檢驗部署應用的狀態是很簡單的： ```shell $ cf apps Getting applications in ... OK name requested state instances memory disk urls ... acloudyspringtime started 1/1 512M 1G acloudyspringtime.cfapps.io ... ``` 一旦Cloud Foundry意識到你的應用已經部署，你就可以點擊給定的應用URI，此處是[acloudyspringtime.cfapps.io/](http://acloudyspringtime.cfapps.io/)。
