elasticsearch java api 配置文件
elasticsearch java api 网址：https://www.elastic.co/guide/en/elasticsearch/client/java-api/current/java-search.html在使用Maven创建Elasticsearch是其pom.xml的文件中必须要加入Log4j 2的依赖
elasticsearch 5.4
org.apache.logging.log4j
log4j-api
2.8.2
org.apache.logging.log4j
log4j-core
2.8.2
And also provide a Log4j 2 configuration file in your>src/main/resources project dir a log4j2.properties file like:
appender.console.type = Consoleappender.console.name = console
appender.console.layout.type = PatternLayoutrootLogger.level = info
rootLogger.appenderRef.console.ref = console
If you want to use another logger than Log4j 2, you can use SLF4J bridge to do that:
org.apache.logging.log4j
log4j-to-slf4j
2.8.2
org.slf4j
slf4j-api
1.7.24
This page lists implementations you can use. Pick your favorite logger and add it as a dependency. As an example, we will use the slf4j-simple logger:
org.slf4j
slf4j-simple
1.7.21
