java - Spring Boot 启动停留在 - INFO : Using a shared selector for servlet write/read

Question

我无法从 eclipse 甚至命令提示符启动我的 spring boot 应用程序，因为应用程序启动卡在以下位置:

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

我没有对我的应用程序进行任何更改，但突然间我无法启动我的应用程序。可能是什么问题？

这似乎是多个 tomcat 库的问题。检查 tomcat 7.x 是否被某些依赖项传递添加。排除它并再次构建运行
