1、el-admin版本为2.5 其中springboot 版本 自行升级至2.2.3 2、部署到容器里启动报错，本地以jar包或war包启动不报错 3、启动时报错信息如下： [0;39morg.springframework.beans.factory.BeanCreationException: Error creating bean with name 'resourceHandlerMapping' defined in class path resource [org/springframework/web/servlet/config/annotation/DelegatingWebMvcConfiguration.class]: Bean instantiation via factory method failed;
