我自己写了deom,没问题，但是我引入到我的项目的时候起服报下面的错误。

以为是log4j冲突，最后各种<exclusions>,还是没有解决。然后我看到确实说找不到类，就给pom添加了下面依赖 <dependency> <groupId>com.lmax</groupId> <artifactId>disruptor</artifactId> <version>3.4.2</version> </dependency>
结果好了，，。。。
现在的问题就是，我为啥demo不需要这个依赖，但是正式项目就需要。 项目是一个Springboot的，我此次是想用sofa-bolt代替自己写的bolt。
我想查查我现在引进来的这个包是咋回事，也没弄明白。。
求大佬解答一下！！
今天我又研究了一下。算是一知半解了，我说一下我的理解。 问题要从 Maven 说起。我原本以为 A->B->C的依赖关系，那就是A-C。今天研究了一下maven机制才明白，scope标签和optional标签可以关闭（更准确说是调整）这个依赖的传递性。 因为sofa配置的上面这个disruptor依赖是test,运行时无效，所以我项目需要对这些sofa依赖的jar进行重新依赖，才能运行。
这让我很奇怪，，servlet-api 或者JDBC我比较好理解，那像sofabolt中的这些依赖都是必要的时候，都需要项目重新进行依赖吗？？
目的是为了使用者能 指定合适的版本吗？ 我会带着这些问题再琢磨琢磨，大家有啥自己的理解也可以说说。
there is a similar issue https://github.com/sofastack/sofa-rpc/issues/1028

bolt 中引入 disruptor依赖陪着的 scope 为 test，在bolt test 下的demo 不会有问题。 在引入项目中之后，日志异步打印时需要disruptor依赖，需要主动引入下。
This is by design, the dynamic selection of logging framework is based on the user relies on a logging framework implementation to select the corresponding logging configuration, the user needs to import the full log4j2 dependencies if using log4j2.
