当前使用版本

mybatis-plus-boot-starter版本3.3.1 springboot版本2.2.5

该问题是怎么引起的？

就是一个正常的web项目，只添加了上面两个依赖，没有写其他的配置，启动项目就报错，但是我把springboot版本降为2.1.6就不报错了

重现步骤

pom.xml如下： ``` org.springframework.boot spring-boot-starter-web org.springframework.boot spring-boot-starter-actuator org.springframework.boot spring-boot-starter-test com.zaxxer HikariCP org.springframework.boot spring-boot-starter-jdbc org.apache.tomcat tomcat-jdbc mysql mysql-connector-java org.projectlombok lombok com.baomidou mybatis-plus-boot-starter 3.3.1 


application.yml如下：

server: port: 8001

spring: application: name: cloud-payment-service datasource: type: com.zaxxer.hikari.HikariDataSource driver-class-name: com.mysql.cj.jdbc.Driver url: jdbc:mysql://localhost:3306/mp?useSSL=false&useUnicode=true&characterEncoding=UTF8&serverTimezone=GMT%2B8 username: root password: 618818 hikari: minimum-idle: 5 idle-timeout: 600000 maximum-pool-size: 10 auto-commit: true pool-name: MyHikariCP max-lifetime: 1800000 connection-timeout: 30000 connection-test-query: SELECT 1
