问题描述
我在其他问题中看到,通常该警告的解决方案是将slf4j从导致该冲突的依赖项中排除,但我无法在我的项目中发现问题.
I've seen in other questions that usually the solution to this warning is to exclude slf4j from the dependency that causes this conflict, but I can't spot the problem in my project.

我运行 mvndependency:tree
命令,这是输出:
I run mvn dependency:tree
command and this is the output:

推荐答案
您可以通过在导致冲突的(pom.xml)依赖项中添加以下排除项来解决此问题.
You can solve the issue by adding the following exclusion in the dependencies (of pom.xml) that caused conflict.
<exclusions>
<exclusion>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
</exclusion>
