一、Java API操作ES
### --- Java API操作ES ### --- 创建一个maven工程：elasticsearch ~~~ # 官网说明： ~~~ https://www.elastic.co/guide/en/elasticsearch/client/java-rest/7.3/java-rest-overview.html
### --- 在pom.xml依赖插件导入文件 <dependencies> <dependency> <groupId>org.elasticsearch.client</groupId> <artifactId>elasticsearch-rest-high-level-client</artifactId> <version>7.3.0</version> <exclusions> <exclusion> <groupId>org.elasticsearch</groupId> <artifactId>elasticsearch</artifactId> </exclusion> </exclusions> </dependency> <dependency> <groupId>org.elasticsearch</groupId> <artifactId>elasticsearch</artifactId> <version>7.3.0</version> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.12</version> <scope>compile</scope> </dependency> <dependency> <groupId>org.testng</groupId> <artifactId>testng</artifactId> <version>6.14.3</version> <scope>test</scope> </dependency> <!--log4j2依赖添加 --> <dependency> <groupId>org.apache.logging.log4j</groupId> <artifactId>log4j-core</artifactId> <version>2.5</version> </dependency> <!-- https://mvnrepository.com/artifact/org.apache.logging.log4j/log4j-api --> <dependency> <groupId>org.apache.logging.log4j</groupId> <artifactId>log4j-api</artifactId> <version>2.5</version> </dependency> <!--es.client.V7.9.0版本依赖于添加 --> <dependency> <groupId>org.elasticsearch.client</groupId> <artifactId>elasticsearch-rest-high-level-client</artifactId> <version>7.9.0</version> <exclusions> <exclusion> <groupId>org.elasticsearch</groupId> <artifactId>elasticsearch</artifactId> </exclusion> </exclusions> </dependency> <dependency> <groupId>org.elasticsearch</groupId> <artifactId>elasticsearch</artifactId> <version>7.9.0</version> </dependency> </dependencies>
二、准备日志配置文件
### --- 准备日志配置文件：resource创建目录：log4j2.xml ~~~ # 官网地址： ~~~ https://www.elastic.co/guide/en/elasticsearch/client/java-rest/7.3/java-rest-high.html<?xml version="1.0" encoding="UTF-8"?> <Configuration status="WARN"> <Appenders> <Console name="Console" target="SYSTEM_OUT"> <PatternLayout pattern="%d{yyyy-mm-dd HH:mm:ss} [%t] %-5p %c{1}:%L - %msg%n" /> </Console> </Appenders> <Loggers> <Root level="info"> <AppenderRef ref="Console" /> </Root> </Loggers> </Configuration>
