springboot Failed to bind properties under 'mybatis-plus.configuration' to com.baomidou.mybatisplus.core.MybatisConfiguration问题

启动springboot时出现错误

Failed to bind properties under 'mybatis-plus.configuration' to com.baomidou.mybatisplus.core.MybatisConfiguration

是因为配置文件.yml

mybatis-plus:
  configuration:
    log-impl: org.apache.ibatis.logging.log4j2.Log4j2LoggerImpl---错了
    map-underscore-to-camel-case: true
修改成

mybatis-plus:
  configuration:
    log-impl: org.apache.ibatis.logging.stdout.StdOutImpl
    map-underscore-to-camel-case: true

问题解决
