Question

我正在开发一个使用Elasticsearch的Java应用程序。我在Java中使用elasticsearch api。我收到NoSuchMethodError错误：

java.lang.NoSuchMethodError： org.apache.logging.log4j.Logger.trace（Ljava / lang / String; Ljava / lang / Object;）V

我已经包含了我的pom文件

请检查类路径上的Log4j依赖项。对于Elasticsearch 5.4.x，您需要Log4j 2.8.2（API和核心），而不是2.3。参见https://www.elastic.co/guide/en/elasticsearch/client/java-api/5.4/_log4j_2_logger.html

如何修复log4j中的“ NoSuchMethodError”错误
