Hot Swapping With Maven, Jetty and IntelliJ

Based on Configuring Jetty, Maven, and Eclipse together with Hot Swap

I've always been a bit jealous when it comes to the Play! framework and the great dev mode they have for hot swapping classes at runtime. Jetty has a configuration setting, scanIntervalSeconds, that mimics this when working with a more traditional WAR, but does so by looking for changes to a file and restarting the server.

Fortunately, Jetty also provides the ability to rapidly test code with hot swapping. No more server restarts. The trick to getting hot swapping to work is to attach a remote debugger to your Jetty process. The following instructions outline how to do this in IntelliJ (tested with IDEA 10.5 CE).

Modify your jetty-maven-plugin to ignore the scan interval

1. Open your pom and locate the plugins section

结合iflux的架构特点怎么才能设计好一个真正好用的校验库，确实有点考验人。
 
之前的iflux解决一部分校验问题，但是也暴露了一些问题。
 
解决问题的问题：
1. 以store为中心，校验声明式，配置规则和message，错误信息自动绑定到store
2. 异步直接走正常的逻辑，不直接支持
 
 
但是根据我们的业务场景也暴露了一些问题，
