jbpm具體應(yīng)用之流程變量與任務(wù)

love/article/details/在上一篇文章《淺析JBPM工作流引擎》中我們介紹了什么是JBPM，以及一個(gè)簡單JBPM實(shí)例，并且我們知道了一個(gè)jpdl[html][html] 1.<?xmlversion="1.0"encoding="UTF-3.<processname="test"key="test"<transitionname="而提交到科 "to="科 "g="-110,-<task name="科"<transitionname="""g="-69,-<task""<transitionname="通過to="end1g="-50,- <endname="end1"15. <startname="start1"通過jpdl文件我們可以看出這個(gè)業(yè)務(wù)流程仍然非常的簡單，就是一個(gè)簡單的任務(wù)傳遞過程。當(dāng)創(chuàng)建好一個(gè)流程實(shí)例的時(shí)候首先進(jìn)入的是“科長”節(jié)點(diǎn)，執(zhí)行人是“”，當(dāng)完成任務(wù)后，提交給任務(wù)人，執(zhí)行“”任務(wù)，執(zhí)行完畢后結(jié)束整個(gè)流程。介紹完業(yè)務(wù)流程后我們通過java代碼介紹流程變量和任務(wù)變量的具體應(yīng)用和區(qū)JbpmTestCase，JbpmUtil，第三個(gè)為子類TestVariable，子類繼承父類并實(shí)現(xiàn)接口。JbpmTestCasestartUp()方法的作用主要是注入各種服務(wù)，省去了子類每次都要[java][java] 1. *@author publicvoiddeploy() }variable.put("userId", ProcessInstanceprocessInstance=nceByKey("mytest",variable.put("userName",Map<String,Object>variable=newHashMap<String,publicvoidcreateInstance()6.publicclassTestVariableextendsJbpmTestCaseimplementsJbpmUtil *流程變 ID", publicvoidgetCurrentActivity() ProcessEngineprocessEngine= ExecutionServiceexecutionService= StringactivityName=executionService.createProcessInstanceQuery().
