如何解决springboot整合spark日志打印级别问题？

一、由于项目中使用到了springboot框架，会导致springboot中的slf4j和spark中的log4j日志组件冲突，springboot推荐使用slf4j+logback的模式来记录日志，logback比log4j更快的实现、更完善的配置，因此：  
**1、pom文件中去除依赖了log4j的jar包**。这一步不做也可以但是会导致，slf4j同时logback和log4j，产生冲突。

**二、在需要记录日志的项目的src/resource目录下，添加logback.xml配置，控制台打印级别设置到DEBUG以上即可**。
