activiti集成spring boot的一个怪问题

最近想集成activti到spring boot中，上网找了一下例子，发现很简单，就开干了!

• 建立maven工程后，加入acitivti的引入

            org.activiti
            activiti-spring-boot-starter-basic
            6.0.0
        
        
            mysql
            mysql-connector-java
        

启动spring boot应用，发现有问题了，报错如下

怎么回事，跑不起来？
按报错，说要在class下找processes这个目录下
手动在resources下建个目录processes，再跑跑。
结果，报错依旧！
后面尝 试在那个processes目录下，放一个流程的xml文件，发现启动成功了！
查一下后台数据库表，发现自动发布了一个流程定义
后面发现加入配置即不会自动扫描该目录了

spring:
  activiti: 
         check-process-definitions: false
