jBPM-userGuide总结

jBPM-userGuide总结

    官方提供的userguide从大的方面阐述了jBPM的基本流程和概念,总结一下其思路：
    一：发布
    1.一切从Configuration开始：Configuration configuration = new Configuration();
    2.然后构建 ProcessEngine：ProcessEngine processEngine = configuration().buildProcessEngine();
    3.有了ProcessEngine,一切就都有了：
        RepositoryService repositoryService = processEngine.getRepositoryService();
        ExecutionService executionService = processEngine.getExecutionService();
        TaskService taskService = processEngine.getTaskService();
        HistoryService historyService = processEngine.getHistoryService();
        ManagementService = processEngine.getManagementService();
    4.发布了：String deploymentId = repositoryService.createDeployment()
                               .addResourceFromClassPath("org/jbpm/Order.jpdl.xml")
                               .deploy();
    5.现在删除它吧：repositoryService.deleteDeployment(deploymentId);
        当然，还有另一个方法：repositoryService. deleteDeploymentCascade(deploymentId);//将删除相关instance和history。
