NetBPM前进了一步，解决了上一个问题

清疚 2022-04-01 10:24 222阅读 0赞

山穷水尽疑无路，柳暗花明又一村。本来以为无法解决NetBPM的问题了，近乎绝望，但是今天中午突然冒出一个想法，否是我没有配置好NetBPM的运行环境呢？因此下午把可以运行的NetBPM的bin目录下的所有文件复制到我的测试项目目录下，同时复制log4net.config到项目目录。然后再跑测试项目，竟然成功了！通过删除文件，发现log4net.config是不要的，当然含Test的dll也是不需要的，其他的还不能完全确定，但MySql.Data.dll和Castle的许多dll是需要的。  
我的测试项目目前结构是：  
PageLoad事件中调用SetContainer函数初始化NetBPM，Unload事件中调用DisposeContainer函数清场。  
页面上放置一个按钮，点击时开始一个新的Holiday request过程，并显示刚刚启动的流程ID。  
需要注意的是要开始新的流程前要调用testUtil.LoginUser(actorId);进行登录，否则无法开始新的流程。  
接下来要进行更深入的研究了。  
最后贴出代码：
