springboot整合activiti时，启动抛异常
nested exception is java.io.FileNotFoundException: class path resource [processes/] cannot be resolved to URL because it does not exist。
解决方案：
两种处理方法
（1）在resource目录下添加processes文件夹，并且文件夹不能为空
（2）在application.properties下家配置
#启动报错class path resource [processes/] cannot be resolved to URL because it does not exist
spring.activiti.check-process-definitions=false
启动时不检查流程文件
