ElasticSearch是一个基于Lucene的分布式、高扩展、高实时的搜索与数据分析引擎。它能很方便的使大量数据具有搜索、分析和探索的能力。充分利用ElasticSearch的水平伸缩性，能使数据在生产环境变得更有价值。
ElasticSearch用于云计算中，能够达到实时搜索，稳定，可靠，快速，安装使用方便。官方客户端在Java、.NET（C#）、PHP、Python、Apache Groovy、Ruby和许多其他语言中都是可用的。

1.pom.xml加入maven依赖，我是用的swagger，所以会加上相关配置，不需要用可以不加。

<!-- Swagger核心包 start -->
<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger2</artifactId>
    <version>2.7.0</version>
</dependency>
<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger-ui</artifactId>
    <version>2.7.0</version>
</dependency>

<!-- elasticsearch -->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-elasticsearch</artifactId>
</dependency>

2.application.properties加入配置

# elasticsearch集群名称，默认的是elasticsearch
spring.data.elasticsearch.cluster-name=my-application
# 节点的地址 注意api模式下端口号是9300，格式=ip:9300
spring.data.elasticsearch.cluster-nodes=**.**.**.**:9300
# 是否开启本地存储
spring.data.elasticsearch.repositories.enabled=true

#配置Swagger相关信息
eureka.instance.prefer-ip-address=true
eureka.instance.status-page-url=http://${spring.cloud.client.ipAddress}:${server.port}/swagger-ui.html

3.创建实体类，indesxName索引值必须全部小写

@Document(indexName = "userinfoindex", type = "userInfo")
public class UserInfo implements Serializable {

private static final long serialVersionUID = 1L;

/** 编号 */
private Long id;
/** 姓名 */
private String name;

/** 年龄 */
private Integer age;

/** 描述 */
private String description;

/** 创建时间 */
private Date createTime;

// getter和setter 略

4.创建Dao层

public interface ESUserInfoRepository extends ElasticsearchRepository<UserInfo, String> {
}

5. 创建Service层

@Service("eSUserInfoService")
public class ESUserInfoServiceImpl implements ESUserInfoService{

	@Autowired
	private ESUserInfoRepository eSUserInfoRepository;

	@Autowired
	ElasticsearchTemplate elasticsearchTemplate;

	@Override
	public boolean insert(UserInfo user) {
		boolean falg=false;
		try{
			eSUserInfoRepository.save(user);
			falg=true;
		}catch(Exception e){
			e.printStackTrace();
		}
		return falg;
	}

	@Override
	public List<UserInfo> search(String searchContent) {
		//查询单个任意值
		//SearchQuery searchQuery = new NativeSearchQueryBuilder().withQuery(queryStringQuery(searchContent)).build();
		//分页查询
		SearchQuery searchQuery = new NativeSearchQueryBuilder().withQuery(queryStringQuery(searchContent)).withPageable(PageRequest.of(0, 20)).build();
		//查询单个指定值
		//SearchQuery searchQuery = new NativeSearchQueryBuilder().withQuery(QueryBuilders.termQuery("name",searchContent)).build();
		List<UserInfo> poetryList = elasticsearchTemplate.queryForList(searchQuery, UserInfo.class);
		return poetryList;
	}
	
}

6.创建controller

@RestController
@RequestMapping("/swaggerTest")
public class SwaggerTestController {

	@Autowired
	private ESUserInfoService esUserInfoService;

	@ResponseBody
	@PostMapping("/search")
	public String queryAccountInfoByAccountName(
		@ApiParam(value = "任意值") @RequestParam(required = true) String searchContent
	) {
		List<UserInfo> userInfo = esUserInfoService.search(searchContent);
		return JSON.toJSONString(userInfo);
}

	@ResponseBody
	@PostMapping("/save")
	public String save(
		@ApiParam(value = "姓名") @RequestParam(required = false) String name,
		@ApiParam(value = "年龄") @RequestParam(required = false) Integer age,
		@ApiParam(value = "描述") @RequestParam(required = false) String description
	) {
		UserInfo userInfo = new UserInfo(name,age,description,new Date());
		esUserInfoService.insert(userInfo);
		return JSON.toJSONString(userInfo);
	}
}	

最后可以直接访问了，添加数据了对应的本地es也能查看到对应的数据和索引
