本文介绍了解决Spring Boot应用中出现的SLF4J多重绑定问题的方法。通过排除spring-boot-starter-web下的logback-classic依赖，避免了log4j-slf4j-impl与logback之间的冲突。

先上一段报错内容

SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/D:/soft/apache-tomcat-8.5.31/webapps/ui/WEB-INF/lib/log4j-slf4j-impl-2.7.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/D:/soft/apache-tomcat-8.5.31/webapps/ui/WEB-INF/lib/logback-classic-1.1.11.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/D:/soft/apache-tomcat-8.5.31/webapps/ui/WEB-INF/lib/slf4j-log4j12-1.7.25.jar!/org/slf4j/impl/StaticLoggerBinder.class]

......

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:/D:/soft/apache-tomcat-8.5.31/webapps/ui/WEB-INF/lib/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

springBoot 本地报错，查了一番，是logback搞得鬼，打开pom依赖树，搜索logback，发现在spring-boot-starter-web下有间接依赖上logback-classisc，搜索大神们的解答，就是在有这个依赖的dependency中除去他就行了。

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
        <exclusions>
                <exclusion>
                    <groupId>ch.qos.logback</groupId>
                   <artifactId>logback-classic</artifactId>
                </exclusion>
           </exclusions>
</dependency>
