推荐答案
运行 mvn依赖:tree
并搜索哪个依赖项具有你不想要的 slf4j
实现,然后 exclude 他们有依赖项排除,如:
Run mvn dependency:tree
and search which dependency have the slf4j
implementations you do not want, then exclude them with a dependency exclusion like:
<dependency>
<groupId>org.someexternallib</groupId>
<artifactId>someexternallibartifact</artifactId>
<version>...</version>
<exclusions>
<exclusion>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
</exclusion>
<exclusion>
<groupId>log4j</groupId>
<artifactId>log4j</artifactId>
</exclusion>
</exclusions>
</dependency>
