出现错误

ERROR StatusLogger Log4j2 could not find a logging implementation. Please add log4j-core to the classpath. Using SimpleLogger to log to the console...

增加 log4j-core 后也不行，控制台就会出现

Exception in thread "main" java.lang.NoClassDefFoundError: ch/qos/logback/classic/Level

错误。

后来我用 spring boot用的是1.56 就不会出现这个问题，正常运行

最后重新安装了ideaIU-2018.2.6 ，在用spring boot 2.10就没问题了
