看起来你引用了两个不兼容的log4j版本，但它们并不能很好地协同工作。使用maven的依赖树功能来识别这些不同版本的来源：

mvn dependency:tree -Dverbose

然后使用maven的排除功能排除错误：

<dependency>
       <groupId>group-of-responsible-jar</groupId>
       <artifactId>artifactId-of-responsible-jar</artifactId>
       <version>...</version>
       <exclusions>
          <exclusion>
            <groupId>log4j</groupId>
            <artifactId>log4j</artifactId>
          </exclusion>
        </exclusions>
</dependecy>
