Alfresco 5.1.x社区版使用Activiti创建过程

Question

我对alfresco不熟悉，我在流程中使用eclipse创建了alfresco activiti进程，我在属性中使用了service task任务选项，任务类型提供了3种类型1 .java class ， 2.expression, 3.java delegates哪种更好地使用外部调用工作流程中的应用程序。

Answer 1

Here is the different between JavaDelegate and Expression

JavaDelegate are instantiated by Spring.This means a workflow can call custom classes that have full access to Alfresco Spring beans. It allows your workflow to make delegate calls that can manipulate content it can also add or remove content from the workflow package itself.You can also add your other complex buisness logic there. So, if you have complex implementation to do during process you should go for this.

Expressions: For doing small operations like updating status of document or updating one or two properties of content within workflow you need to consider this. Because in expression you can use alfresco javascript to achieve all those things.

Hope this helps
