JRebel

Continuous integration is often a goal of software-as-a-service products. What if you didn't even need to wait for the build to finish to see code changes live?

持续集成常常是SaaS（软件即服务）产品的一个目标。如果你不需要等待构建就可以看到代码变化效果的话会怎么样呢？

That's what JRebel does. Once you hook up your server to your JRebel client, you can see changes on your server instantly. It's a huge time savings when you want to experiment quickly.

这就是JRebel所做的。一旦你把你的服务连接到JRebel客户端，你就可以在服务器上即时看到变化了。这可以让你在快速试验的时候节约大量时间。
