问题描述
我正在尝试使用带有sprintboot应用程序的Elasticsearch 5.0传输客户端。 Elasticsearch 5.0客户端使用log4j2,当我启动我的springboot服务时,ES客户端抛出错误,因为它找不到log4j2类。我尝试了很多组合,但没有运气。
有没有人在springboot应用程序中使用ES 5客户端?
I am trying to use Elasticsearch 5.0 transport client with a sprintboot application. Elasticsearch 5.0 client uses log4j2 and when I launch my springboot service, ES client throws error as it could not find log4j2 classes. I have tried many combinations but no luck yet.Has anybody used ES 5 client within a springboot application?
这是我的pom

推荐答案
请添加依赖关系
- log4j -api
- log4j-core
- log4j-slf4j-impl
目前最新版本是2.8。
Currently the latest version is 2.8.
您可以删除log4j-over-slf4j依赖关系,这是旧的Log4j 1.2。
You can remove the log4j-over-slf4j dependency, this is for the old Log4j 1.2.
