我引入了spring-boot-starter-web，使用了它自己的spring-boot-starter-logging框架，在yaml中指定了配置文件，并报告了启动错误yaml：
logging:

SLF 4J在1.x和2.x版本之间彻底改变了它的实现方式。在1.x中，绑定类需要提供一个名为
org.slf4j.impl.StaticLoggerBinder的类--这个类是缺失的。在2.x中，它使用ServiceLoader机制。Sping Boot 目前仍然使用SLF 4J 1.7.36，通过
spring-boot-starter-web-〉spring-boot-starter-〉spring-boot-starter-logging。后者依赖于一些SLF 4J桥，以及logback-classic，后者反过来依赖于SLF 4J 1.7.32。我认为1.7.36“赢”了1.7.32。除非您的其他依赖项中有一个对SLF 4J 2.x的可传递依赖项，否则一切都应该正常工作。如果您这样做了，那么您将混合使用SLF 4J 1.x和2.x，这根本行不通。将2.x依赖项替换为1.x依赖项，您应该可以正常工作（除非您使用2.x中添加的fluent API）。
