本地开发spark项目时，测试案例运行时出现以下错误：

Exception in thread "main" java.lang.NoClassDefFoundError: org/slf4j/impl/StaticLoggerBinder

Caused by: java.lang.ClassNotFoundException: org.slf4j.impl.StaticLoggerBinder

解决方法：

在项目的`pom.xml`文件中添加以下依赖：

<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-log4j12</artifactId>
    <version>1.6.6</version>
</dependency>
<dependency>
    <groupId>log4j</groupId>
    <artifactId>log4j</artifactId>
    <version>1.2.17</version>
</dependency>
