JBPM4.0CR1和Spring的整合

前两天看到JBPM4.0c出CR1了，为之兴奋，马上下载了下来，直到这会才算整合成功，发布成功了流程。

跟了四个版本，发现自己还是没有完全理解JBPM，所以之前的整合都是野派路子。今天下午看到ronghao写的 《jBPM4与Spring的集成》，以及参考 http://www.slideshare.net/guest8d4bce/spring-integration-with-jbpm4，终于完美整合成功了。

其实jbpm的很多信息，都是通过jbpm.cfg.xml文件设置的，之前我整合的时候是不要这个文件的，所以总是发现很多地方不通畅。

当然有些地方还是根据自己的需要，修改了源代码，这个倒也不是很重要。把用到的配置文件贴出来，供大家参考。
