在本次的 会议上， 可以说是动作连连。
1. 发布新的 。
2. 发布新的 Spring 家族产品 。
3. 并且宣布 将免费提供给开发人员使用。
4. 。
Spring Roo 是一种 Spring 开发的辅助工具，当你感叹 Ruby on Rails，CakePHP，Seam Gen时，或许应该尝试一下Spring Roo。
Spring 官方博客的
Spring Roo 介绍 。
下载 ，当前最新版本是 1.0 Alpha 2。
解压至硬盘，设置环境变量 ROO_HOME ，指向 roo 所在的目录。并将 $ROO_HOME/bin 添加到系统的 Path 中。
在Linux 你可以写入当前用户的 .bashrc 文件。
export ROO_HOME=/home/hantsy/libs/java/roo-1.0.0.A2
export PATH=$PATH:$ROO_HOME/bin
执行 source ~/.bashrc 让它立即生效。
执行 roo.sh ，你可以进入 Spring Roo 命令行操作界面。
[hantsy@localhost samples]$ ../bin/roo.sh

你会发现 Spring Roo 生成的是一个 Maven 项目，你可以将它导入 Eclipse 中，你需要安装 和 插件。
在项目的中目录中执行 mvn eclipse:eclipse ，maven 会帮你生成一个 eclipse 项目。
现在你可以将它导入到 eclipse 中。
它是一个 web 项目，可以把它部署到服务器上运行。
