将 Activiti 5 BPMN 流程迁移到 Flowable 6

Question

我正在按照 https://blog.flowable.org/2019/08/07/migration-of-a-bpmn-process/ 处的 Flowable 指南将我的 Activiti 5 流程实例迁移到 Flowable 6.5 和 https://flowable.com/open-source/docs/bpmn/ch09-ProcessInstanceMigration/#process-instance-migration-experimental

进行一些调整，因为创建 ProcessInstanceMigrationBuilder 的方法已移至 ProcessMigrationService，所以我的代码看起来像

processMigrationService
    .createProcessInstanceMigrationBuilder()
    .migrateToProcessDefinition(v6ProcessDefinition.getId()) // I checked it using engineVersion <> Flowable5Util.V5_ENGINE_TAG
    .migrate(processInstance.getId())

org.flowable.common.engine.api.FlowableException: Flowable 5 process definitions are not supported
    at org.flowable.engine.impl.dynamic.AbstractDynamicStateManager.resolveActiveExecution(AbstractDynamicStateManager.java:186) ~[flowable-engine-6.5.0.jar:6.5.0]
    at org.flowable.engine.impl.dynamic.AbstractDynamicStateManager.resolveMoveExecutionEntityContainers(AbstractDynamicStateManager.java:108) ~[flowable-engine-6.5.0.jar:6.5.0]

    at org.flowable.engine.impl.ProcessMigrationServiceImpl.migrateProcessInstance(ProcessMigrationServiceImpl.java:62) ~[flowable-engine-6.5.0.jar:6.5.0]
    at org.flowable.engine.impl.migration.ProcessInstanceMigrationBuilderImpl.migrate(ProcessInstanceMigrationBuilderImpl.java:138) ~[flowable-engine-6.5.0.jar:6.5.0]

但是当 Flowable 在我的 v5 bpmn 流程实例中执行一些逻辑时，我得到一个异常说“不支持 Flowable 5 流程定义”。我在这里感到困惑，Flowable提供的API的目的是将v5 bpmn流程实例迁移到v6，当我运行它时，它说不支持我的流程定义。

Answer 1

迁移的目的API是支持在 Flowable 6 流程实例的不同流程定义版本之间迁移。

不支持将流程实例从 Activiti / Flowable 5 迁移到 Flowable 6，因为它们具有不同的结构。兼容层在那里，所以你可以保持运行旧的 Flowable 5 进程实例与 Flowable 6 进程实例并行。
