springboot log4j2 報錯SLF4J: Class path contains multiple SLF4J bindings

寫完的springboot後，添加日誌配置，習慣用sl4j+log4j配置，網上找了幾篇博文參考，配置依賴照寫，啓動結果報錯： Class path contains multiple SLF4J bindings

SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/E:/maven_repository_new/org/apache/logging/log4j/log4j-slf4j-impl/2.11.2/log4j-slf4j-impl-2.11.2.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/E:/maven_repository_new/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.apache.logging.slf4j.Log4jLoggerFactory]

重新又看了這位大神寫的博客：原文鏈接

在pom中加入：

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter</artifactId>
            <exclusions>
                <exclusion>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-starter-logging</artifactId>
                </exclusion>
            </exclusions>
        </dependency>

其他的還確實不管用，加了上面的就OK了，但是大神的分析方法我確實沒有在IDEA中看到，不信你看：

不知道是不是我的idea的版本太低，抽空研究一下，所以後面說的分析也就夭折了，不過分析方法是可以學習一下的，感謝大神的分享[此處有10086朵花花和鼓掌]
