今天在做将本地的springboot项目通过docker的方式部署到生产环境的工作时，发现docker下的jar包启动后包下面异常，经过网上调研，一开始都是说是包冲突之类的文章，尝试添加相关包未解决。后又遇到说是tomcat版本问题，觉得这个原因不是这次遇到这个问题的原因，因而未尝试。最后查阅后发先一篇文章说其是jdk版本的问题，又结合自己本地的jdk版本确实是比生产环境高。然后将生产环境docker的jdk镜像版本由openjdk:8-jre 调整到了 openjdk:8-jdk,发版后问题依旧。最后将jdk版本调到了 openjdk:11，最终项目启动成功不再报异常。

总结：JDK版本过低，替换为高版本即可。
