問題原因

     日誌級別的問題，將日誌級別改為info

問題解決辦法

第一步、匯入maven依賴

            <dependency>
                <groupId>log4j</groupId>
                <artifactId>log4j</artifactId>
                <version>1.2.17</version>
            </dependency>

第二步、配置檔案修改application.yml

logging:
  level:
    root:  ERROR
    org.springframework:  DEBUG
    org.mybatis:  DEBUG
    org.springframework.scheduling: INFO

加上這個org.springframework.scheduling: INFO就可以解決問題了
