原因

caused by the use of internal JDK API in CGLIB, You may safely ignore this for the time being; a Spring Framework 4.3 based application will nevertheless run fine.
For full JDK 9+ support, please upgrade to Spring Framework 5.1+ / Spring Boot 2.1+. quoto

JDK9+对一些API进行了调整，但是老版本的软件运行还是会调用这些API，官方不建议这么做然后给出警告

解决方法

或者选择无视(不建议
