抛[activiti.cfg.xml] cannot be opened because it does not exist错误

这个[activiti.cfg.xml] cannot be opened because it does not exist错误信息是告诉我们，该项目缺少activiti.cfg.xml配置文件，activiti默认情况下会在classpath路径下面去寻找名为activiti.cfg.xml的配置文件，如果没有找到，则抛出该异常信息。

解决办法：

在classpath目录下面缺少activiti.cfg.xml配置文件。创建activiti.cfg.xml配置文件。
