问题描述
每当需要更改流程定义时，都必须重新部署流程定义。似乎会创建流程定义的新版本。
Whenever I need to make a change in the process definition I have to re deploy the process definition.It seems that creates a new version of the process definition.
有没有一种方法可以更新现有流程定义，而不是一直创建新版本。
Is there a way where I can update the existing process definition and not create a new version all the time.
如果有新流程，旧流程实例会怎样？版本的流程定义到位。
What will happen to the old process instances if there is a new version of process definition in place.
对上述查询提供的任何帮助均会受到欢迎。
Any help on the above queries is appreciated.
推荐答案
我认为Activiti API不提供一种无需部署新版本即可替换现有流程定义的方法。
I don't think the Activiti API provides a way to replace an existing process definition without deploying a new version.
部署新版本时就流程而言，旧版本上的任何现有流程实例将继续在旧版本上运行。
When you deploy a new version of a process, any existing process instances on the old version continue running on the old version.
但是，有一个类，可用于更改流程实例上的流程版本。不过，它不是智能的；它只是更改版本号，而不会更改任何其他运行时数据，因此，如果您在流程定义中进行了不兼容的更改，它可能会破坏流程实例。
However, there is a SetProcessDefinitionVersionCmd class you can use to change the process version on a process instance. It's not "smart", though; it simply changes the version number, and doesn't change any other runtime data, so it can break process instances if you make an incompatible change in the process definition.
