一、问题的现象

1、使用spring-boot-starter-web重构项目时，遇到报错：

SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/C:/Users/mou/.m2/repository/org/slf4j/slf4j-log4j12/1.7.30/slf4j-log4j12-1.7.30.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/C:/Users/mou/.m2/repository/ch/qos/logback/logback-classic/1.2.3/logback-classic-1.2.3.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:/C:/Users/mou/.m2/repository/org/slf4j/slf4j-log4j12/1.7.30/slf4j-log4j12-1.7.30.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.Log4jLoggerFactoryat org.springframework.util.Assert.instanceCheckFailed(Assert.java:702)at org.springframework.util.Assert.isInstanceOf(Assert.java:602)

二、解决方案

原因：看冲突的内容应该是指我的旧项目和Spring Boot中自带的slf4j包冲突了。
解决：去除Spring Boot Web启动器中的日志依赖

<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId><exclusions><exclusion><groupId>org.slf4j</groupId><artifactId>slf4j-log4j12</artifactId></exclusion><exclusion><groupId>ch.qos.logback</groupId><artifactId>logback-classic</artifactId></exclusion></exclusions></dependency>

三、排查方式

IDEA开发工具可以右键POM文件，查看导入的依赖，再按ctrl+F可以查看依赖的位置。
