... 64 common frames omitted 其实这个不是spring boot + mybatis的问题， 其实是为了使MySQL JDBC驱动程序的5.1.33版本与UTC时区配合使用，必须在连接字符串中明确指定serverTimezone。
spring.datasource.url = jdbc:mysql://localhost:3306/blog?useUnicode=true&characterEncoding=utf-8&useLegacyDatetimeCode=false&serverTimezone=UTC在上面图片见图的地方明确指定serverTimezone就可以了
