spring boot 启动报错 org/springframework/core/ErrorCoded

新建了一个spring boot Junit 项目，跑着玩。。结果启动报错。因为 SpringBoot提倡简化开发，不需要自己管理很多spring的依赖所以，从其他项目拷贝过来的很多依赖。。导致报错如下，

java.lang.NoClassDefFoundError: org/springframework/core/ErrorCoded

试着引入 spring-core 的maven 依赖

加入后继续报另一个错

删掉所有 spring的依赖，如下的

只剩下spring boot的依赖

继续报错

将spring boot 版本从1.5.3 升级为2.1.2

与

保持一致。好了，下面是我自己的业务报错了。说是找不到数据库的Mapper了

好了，老项目中有一个 exclue注解这个要干掉

好了，至此，结束！项目跑起来了！发个绿色的【Tests passed】祝贺下！
