springboot 2.6.x 启动报错 Class path contains multiple SLF4J bindings的解决

SLF4J: Found binding in [jar:file:/D:/maven/repository/org/slf4j/slf4j-log4j12/1.6.4/slf4j-log4j12-1.6.4.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.

原因分析：

slf4j-log4j12 包与 spring-boot-starter-test 自带的包冲突

问题解决：排除其中一个的依赖

    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-log4j12</artifactId>
        <version>1.6.4</version>
    </dependency>

再次启动无报错警告发生，错误排除
