Spring boot 集成ElasticSearch
Spring boot 集成ElasticSearch * [第一步Spring boot集成ELasticSearch][2] * [第二步Spring boot中配置ElasticSearch][3] * [第三步 创建操作的实体Bean（我创建的是UserItemBean）][4] * [第四步 使用ElasticSearch的API进行测试][5] Spring boot 集成ElasticSearch 第一步Spring boot集成ELasticSearch `<dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-elasticsearch</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> <exclusions> <exclusion> <groupId>org.junit.vintage</groupId> <artifactId>junit-vintage-engine</artifactId> </exclusion> </exclusions> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>1.2.68</version> </dependency> </dependencies> ` > > Spring boot集成ElasticSearch主要依赖 > > ``` `spring-boot-starter-data-elasticsearch ` 这里需要大家特别注意自己使用的ElasticSearch的版本 是否和自己的版本一致 我这里是使用的最新的ElasticSearch 7.8.0 需要配置版本 <properties> <java.version>1.8</java.version> <elasticsearch.version>7.8.0</elasticsearch.version> </properties> ### 第二步Spring boot中配置ElasticSearch {#toc_2} > 创建一个<mark>ElasticSearchConfig</mark>的类，配置在下ElasticSearch的高级客户端api > > ``` `import org.apache.http.HttpHost; import org.elasticsearch.client.RestClient; import org.elasticsearch.client.RestHighLevelClient; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; /** * Elasticsearch 配置 */ @Configuration public class ElasticSearchConfig { @Bean public RestHighLevelClient restHighLevelClient(){//配置rest客户端 RestHighLevelClient client = new RestHighLevelClient( RestClient.builder( new HttpHost("192.168.1.187", 9200, "http"))); return client; } } ` 注意：这里可以配置多个ElasticSearch 只需要创建多个HttpPost即可 ...
