我正在运行Linux 16.0 LTS和open-jdk版本1.8.0_212。 在Maven上清洁并安装我会得到
类路径包含多个SLF4J绑定
甚至在尝试运行mvn dependency:tree
时,如果没有树结构,我也会遇到相同的错误。
我正在尝试从Spring Boot运行基本启动程序。
我尝试添加对Web入门依赖项的排除。

SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/usr/lib/jvm/java-8-openjdk-amd64/jre/lib/ext/slf4j-log4j12-1.6.6.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/usr/lib/jvm/java-8-openjdk-amd64/jre/lib/ext/slf4j-log4j12-1.7.25.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.
SLF4J: Actual binding is of type [org.slf4j.impl.Log4jLoggerFactory]
Exception in thread "main" java.lang.IllegalArgumentException: LoggerFactory is not a Logback LoggerContext but Logback is on the classpath. Either remove Logback or the competing implementation (class org.slf4j.impl.Log4jLoggerFactory loaded from file:/usr/lib/jvm/java-8-openjdk-amd64/jre/lib/ext/slf4j-log4j12-1.6.6.jar). If you are using WebLogic you will need to add 'org.slf4j' to prefer-application-packages in WEB-INF/weblogic.xml: org.slf4j.impl.Log4jLoggerFactory
