我介绍了spring web，使用了自己的spring-启动-启动-日志框架，在yaml中指定了配置文件，并报告了启动错误yaml：

SLF4J彻底改变了它在1.x和2.x版本之间实现的方式。在1.x中，绑定类需要提供一个名为org.slf4j.impl.StaticLoggerBinder的类--缺少的类。在2.x中，它使用ServiceLoader机制。
Spring目前仍然使用SLF4J 1.7.36，通过spring-boot-starter-web -> spring-boot-starter -> spring-boot-starter-logging。后者依赖于一些SLF4J桥，以及logback-classic，后者又依赖于SLF4J 1.7.32。我认为1.7.36胜于1.7.32。
除非您的其他依赖项之一对SLF4J 2.x具有传递依赖关系，否则一切都应该正常工作。如果您这样做了，那么您就有了SLF4J 1.x和2.x的混合，这是完全行不通的。将2.x依赖项替换为1.x依赖项，您应该会很好(除非使用2.x中添加的fluent API )。
