问题描述
从 activiti 5 迁移到 6 后，我在初始化应用程序时出现此错误：
Caused by: org.activiti5.engine.ActivitiException: UnkNown method used in expression: #{elCorService.makePlat(corWorkflowService.buildContext(execution))}
at org.activiti5.engine.impl.el.JuelExpression.getValue(JuelExpression.java:56)
at org.activiti5.engine.impl.bpmn.behavior.ServiceTaskExpressionActivityBehavior.execute(ServiceTaskExpressionActivityBehavior.java:71)
... 199 more
... Caused by: javax.el.MethodNotFoundException: Method not found: class com.sun.proxy.$Proxy360.buildContext(org.activiti.engine.impl.persistence.entity.ExecutionEntityImpl)
解决方法
您是否有引用“org.activiti.engine.impl.persistence.entity.ExecutionEntity”而不是“org.activiti.engine.impl.persistence.entity.ExecutionEntityImpl”的自定义代码？特别是“corWorkflowService.buildContext()”。
这是记录在 5 到 6 之间的更改：https://www.activiti.org/migration
5.7. EntityManagers
In Activiti version 5,all EntityManager (responsible for persistence but also certain
logic) classes did not have an interface. In version 6,all EntityManager classes have
been renamed to have Impl as suffix and an interface without the suffix. This
effectively means that the version 5 EntityManager class name is now the name of the
corresponding interface.
All EntityManager interfaces extend the generic
org.activiti.engine.impl.persistence.entity.EntityManager interface. All
implementation classes extend a generic AbstractEntityManager interface.
Also,for consistency: * The UserIdentityManager interface has been renamed to
UserEntityManager * The GroupIdentityManager interface has been renamed to
GroupEntityManager
