解决springboot的log冲突

LoggerFactory is not a Logback LoggerContext but Logback is on the classpath. Either remove Logback or the competing implementation (class org.slf4j.impl.SimpleLoggerFactory) Object of class [org.slf4j.impl.SimpleLoggerFactory] must be an instance of class ch.qos.logback.classic.LoggerContext

Add exclusion to both the spring-boot-starter and spring-boot-starter-web to resolve the conflict.
