activiti整合springboot的一個怪問題

最近想整合activti到spring boot中，上網找了一下例子，發現很簡單，就開幹了!

• 建立maven工程後，加入acitivti的引入

<dependency>
            <groupId>org.activiti</groupId>
            <artifactId>activiti-spring-boot-starter-basic</artifactId>
            <version>6.0.0</version>
        </dependency>
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
        </dependency>

啟動spring boot應用，發現有問題了，報錯如下

怎麼回事，跑不起來？
按報錯，說要在class下找processes這個目錄下
手動在resources下建個目錄processes，再跑跑。
結果，報錯依舊！
後面嘗 試在那個processes目錄下，放一個流程的xml檔案，發現啟動成功了！
查一下後臺資料庫表，發現自動釋出了一個流程定義
後面發現加入配置即不會自動掃描該目錄了

spring:
  activiti: 
         check-process-definitions: false
