报错原因：pom中没有slf4j的相关框架实现，即现在项目只有框架门面，而缺少具体的框架实现。
解决方案：pom中添加如下2个依赖即可解决问题。
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.7.33</version>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
<version>1.7.33</version>
</dependency>
