篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了springboot1.5.13集成Elasticsearch6.1相关的知识，希望对你有一定的参考价值。
由于公司业务需要，需要springboot整合elasticsearch6.1，之前在网上费了好大的劲的才整合好，在此记录下，楼主使用的版本是springboot1.5.13和ElasticSearch6.1.1，其他版本的同学可做参考！
本文使用官方推荐使用Java High Level REST Client，楼主也集成成功，故在此分享一下！
1.核心pom的xml，其他版本的同学请根据自己情况进行修改
1 <parent> 2 <groupId>org.springframework.boot</groupId> 3 <artifactId>spring-boot-starter-parent</artifactId> 4 <version>1.5.13.RELEASE</version> 5 <relativePath/> <!-- lookup parent from repository --> 6 </parent> 7 8 <properties> 9 <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> 10 <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> 11 <java.version>1.8</java.version> 12 </properties> 13 14 <dependencies> 15 <dependency> 16 <groupId>org.springframework.boot</groupId> 17 <artifactId>spring-boot-starter-web</artifactId> 18 </dependency> 19 <dependency> 20 <groupId>org.springframework.boot</groupId> 21 <artifactId>spring-boot-starter-test</artifactId> 22 </dependency> 23 <dependency> 24 <groupId>org.springframework.boot</groupId> 25 <artifactId>spring-boot-devtools</artifactId> 26 </dependency> 27 <!-- Elasticsearch Dependencies --> 28 <dependency> 29 <groupId>org.elasticsearch</groupId> 30 <artifactId>elasticsearch</artifactId> 31 <version>6.1.1</version> 32 </dependency> 33 <dependency> 34 <groupId>org.elasticsearch.client</groupId> 35 <artifactId>elasticsearch-rest-high-level-client</artifactId> 36 <version>6.1.1</version> 37 </dependency> 38 <dependency> 39 <groupId>org.elasticsearch.client</groupId> 40 <artifactId>elasticsearch-rest-client</artifactId> 41 <version>6.1.1</version> 42 </dependency> 43 <dependency> 44 <groupId>org.elasticsearch.client</groupId> 45 <artifactId>elasticsearch-rest-client-sniffer</artifactId> 46 <version>6.1.1</version> 47 </dependency> 48 <!--日志组件--> 49 <dependency> 50 <groupId>org.apache.logging.log4j</groupId> 51 <artifactId>log4j-api</artifactId> 52 <version>2.8.2</version> 53 </dependency> 54 <dependency> 55 <groupId>org.apache.logging.log4j</groupId> 56 <artifactId>log4j-core</artifactId> 57 <version>2.8.2</version> 58 </dependency> 59 <!--gson组件--> 60 <dependency> 61 <groupId>com.google.code.gson</groupId> 62 <artifactId>gson</artifactId> 63 <version>2.8.2</version> 64 </dependency> 65 <!-- https://mvnrepository.com/artifact/javax.inject/javax.inject --> 66 <dependency> 67 <groupId>javax.inject</groupId> 68 <artifactId>javax.inject</artifactId> 69 <version>1</version> 70 </dependency> 71 </dependencies>
2.elasticsearch配置类
1 package cn.ixan.elasticstack.configuration; 2 3 import org.apache.http.HttpHost; 4 import org.elasticsearch.client.RestClient; 5 import org.elasticsearch.client.RestHighLevelClient; 6 import org.slf4j.Logger; 7 import org.slf4j.LoggerFactory; 8 import org.springframework.beans.factory.DisposableBean; 9 import org.springframework.beans.factory.FactoryBean; 10 import org.springframework.beans.factory.InitializingBean; 11 import org.springframework.beans.factory.annotation.Value; 12 import org.springframework.context.annotation.Configuration; 13 14 /** 15 * 不推荐使用elasticsearch spring-data 16 * 所以需要自己注入生成客户端 17 * 这个三个接口可以使用 AbstractFactoryBean 通过继承重写方法代替 18 * Created by [email protected] on 2018/6/16. 19 */ 20 @Configuration 21 public class ElasticsearchConfiguration implements FactoryBean<RestHighLevelClient>, InitializingBean, DisposableBean { 22 private final Logger logger = LoggerFactory.getLogger(this.getClass()); 23 24 private RestHighLevelClient restHighLevelClient; 25 @Value("${spring.data.elasticsearch.cluster-nodes}") 26 private String clusterNodes; 27 28 29 /** 30 * 控制Bean的实例化过程 31 * @return 32 * @throws Exception 33 */ 34 @Override 35 public RestHighLevelClient getObject() throws Exception { 36 return restHighLevelClient; 37 } 38 /** 39 * 获取接口返回的实例的class 40 * @return 41 */ 42 @Override 43 public Class<?> getObjectType() { 44 return RestHighLevelClient.class; 45 } 46 47 @Override 48 public void destroy() throws Exception { 49 try { 50 if(null != restHighLevelClient){ 51 restHighLevelClient.close(); 52 } 53 } catch (final Exception e) { 54 logger.error("Error closing ElasticSearch client: ", e); 55 } 56 } 57 58 @Override 59 public boolean isSingleton() { 60 return false; 61 } 62 63 @Override 64 public void afterPropertiesSet() throws Exception { 65 restHighLevelClient = buildClient(); 66 } 67 68 private RestHighLevelClient buildClient() { 69 try { 70 restHighLevelClient = new RestHighLevelClient( 71 RestClient.builder( 72 new HttpHost( 73 clusterNodes.split(":")[0], 74 Integer.parseInt(clusterNodes.split(":")[1]), 75 "http"))); 76 } catch (Exception e) { 77 logger.error(e.getMessage()); 78 } 79 return restHighLevelClient; 80 } 81 }
3.application.properties
spring.data.elasticsearch.cluster-nodes=127.0.0.1:9200
4.测试
1 package cn.ixan.elasticstack.controller; 2 3 import org.elasticsearch.action.get.GetRequest; 4 import org.elasticsearch.action.get.GetResponse; 5 import org.elasticsearch.client.RestHighLevelClient; 6 import org.springframework.web.bind.annotation.RequestMapping; 7 import org.springframework.web.bind.annotation.RestController; 8 9 import javax.inject.Inject; 10 import java.io.IOException; 11 12 @RestController 13 @RequestMapping("/elastic") 14 public class ElasticController { 15 @Inject 16 private RestHighLevelClient client; 17 18 /** 19 * 测试查询文档 20 */ 21 @RequestMapping("/fetchIndex") 22 public Object getIndexTest() { 23 GetRequest request = new GetRequest("magic", "employee", "1"); 24 try { 25 GetResponse response = client.get(request); 26 System.out.println(response); 27 return request; 28 } catch (IOException e) { 29 e.printStackTrace(); 30 return null; 31 } 32 } 33 34 }
5.准备测试数据，这里楼主使用postman,其他同学可选择使用其他工具,测试数据类似如下，看不懂的请移步先学习ElasticSearch服务器开发(第二版)
curl -XPUT http://localhost:9200/magic/employee/1 -d ‘{"title": "New version of Elasticsearch released!", content": "Version 1.0 released today!", "tags": ["announce", "elasticsearch", "release"] }‘
6.浏览器测试
http://localhost:8080/elastic/fetchIndex
ok，如果到这里你可以查询到数据，那么你已经完成了springboot1.5集成ElasticSearch6.1
