YAWL工作流引擎启动流程实例过程详录

来源：互联网 发布：虚拟代理软件 编辑：程序博客网 时间：2024/04/30 18:25

本来是打算了解一下启动流程时传入流程数据的XML格式，顺便把整个引擎的流程启动过程跟踪了一下，其中包含了引擎运转最核心的算法continue if possible，并记录了所有引擎内部DEBUG的输出。

 

1---引擎服务端接收到post请求，开始启动流程
InterfaceB_EngineBasedServer::doPost() request.parameters =
[DEBUG]org.yawlfoundation.yawl.engine.interfce.interfaceB.InterfaceB_EngineBasedServer.debug-     request.getParameter(caseParams) =<Root><inputString>my

test</inputString><inputBoolean>true</inputBoolean></Root>
这里是流程启动时传入case data的格式：<Root><name>value</name>...</Root>
[DEBUG]org.yawlfoundation.yawl.engine.interfce.interfaceB.InterfaceB_EngineBasedServer.debug-     request.getParameter(version) = 0.1
