Don't understand what went wrong any help will be great. Please let me know if required more information

尝试了此解决方案，但没有帮助 Log4j2找不到具有Sprint Boot的日志记录实现

Tried this solution but no help Log4j2 could not find a logging implementation with Sprint Boot

推荐答案

将依赖项添加到pom

Add dependency to your pom

<dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-to-slf4j</artifactId>
    <version>2.8.2</version>
</dependency>

这是因为就我而言，log4j是从Elasticsearch打印的.我已经实现了logback.xml进行日志记录.要克服默认的log4j错误消息，可以使用slf4j覆盖.

This is because for my case the log4j is printing from Elasticsearch. I have implemented logback.xml for logging. To overcome default log4j error messages, you can override with slf4j.
