Resolving conflicts between Spring-boot-starter-logging and log4j

The build project encountered an error because the company configured the check rule in Super-bom:

[ERROR] [XXX Enforcer Rules] Find duplicateclasses

Found in:
Org.apache.logging.log4j:log4j-slf4j-impl:jar:2.6.2:compile
Ch.qos.logback:logback-classic:jar:1.1.7:compile
Duplicate classes:
Org/slf4j/impl/staticmdcbinder.class
Org/slf4j/impl/staticmarkerbinder.class
Org/slf4j/impl/staticloggerbinder.class

I did not directly quote Logback-classic in the POM, see this error is ignorant, I did not quote this in the Pom ah.

Resolution process:

It is possible to find out which package is dependent on Logback-classic by IntelliJ Idea's package dependency. Operation: View->tool window->maven Projects, this button:

You can see the package dependency graph, which may be more complex and messy, and can be searched after Ctrl+f:

This blog has mentioned how to deal with this problem: http://blog.csdn.net/xudan1010/article/details/ 52890102, that is, use excusions to exclude spring-boot-starter dependence on spring-boot-starter-logging, and then introduce Log4j-slf4j-impl

        <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>

You can also use commands to see dependencies: MVN dependency:tree | grep log
