IntelliJ IDEA出现错误Exception in thread "main" java.lang.NoClassDefFoundError: org/slf4j/LoggerFactory

解决方案：

1、找到项目的pom.xml文件，添加依赖。如下图：

 

代码：

        <dependency>
            <!-- https://mvnrepository.com/artifact/org.slf4j/slf4j-api -->
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-api</artifactId>
        </dependency>

        <dependency>
            <!-- https://mvnrepository.com/artifact/org.slf4j/slf4j-log4j12 -->
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-log4j12</artifactId>
        </dependency>

        <dependency>
            <!-- https://mvnrepository.com/artifact/org.slf4j/slf4j-simple -->
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-simple</artifactId>
        </dependency>

2、然后运行clean清除一下缓存，如下图：

3、最后运行项目，就成功啦！
