springboot使用logback会遇到的坑

Caused by: java.lang.IllegalArgumentException: LoggerFactory is not a Logback LoggerContext but Logback is on the classpath. Either remove Logback or the competing implementation (class org.apache.logging.slf4j.Log4jLoggerFactory loaded from file:/C:/Users/fyk/.m2/repository/org/apache/logging/log4j/log4j-slf4j-impl/2.7/log4j-slf4j-impl-2.7.jar). If you are using WebLogic you will need to add 'org.slf4j' to prefer-application-packages in WEB-INF/weblogic.xml: org.apache.logging.slf4j.Log4jLoggerFactory

在spring boot中导入logback jar包会与spring-boot-starter-web冲突，应该是springboot中已经包含了这个包，

 		
			ch.qos.logback
			logback-classic
			1.2.3
		

去掉这个导入就好了
