Spring Roo 是SpringSource新的开放源码技术，该技术主要面向企业中的Java开发者，使之更富有成效和愉快的进行开发工作，而不会牺牲工程完整或灵活 性。无论你是一个新的Java开发人员或经验丰富的架构师，Spring Roo 都可以在短短几分钟内构建一个全面的工作应用。
该版本包含 120 项改进，主要有：
- Productivity in the cloud: As mentioned above, Roo now provides broad Cloud Foundry integration. With Cloud Foundry and Roo you can build normal Java-based applications (complete with normal MySql persistence etc) and have these hosted in our groundbreaking new developer cloud. The Roo integration allows you to build, deploy and manage Cloud Foundry applications directly from Roo shell. Learn more in the separate announcement post.
- Shell usability: There have been many usability improvements made in this new release. Apple Terminal users now have the full Roo shell experience, including “flash” message support. We’ve also improved code-assist improved code assist in this release.
- Primary key enhancements: You can now use composite primary keys with the Data-on-Demand and Integration Test features, allowing automatic testing of a wider range of application entities (this will of particular benefit to those using Roo’s incremental database reverse engineering).
- Process improvements: The Roo project now operates a continuous integration build server so that you can enjoy the latest snapshot builds of both Roo and its major add-ons. This allows the community to more easily try out new fixes and features.
