最基礎的整合：

一、maven依賴

<parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.0.0.RELEASE</version><relativePath /> <!-- lookup parent from repository --></parent><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-data-elasticsearch</artifactId></dependency><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId></dependency></dependencies>

二、配置文件application.yml

spring:data:elasticsearch:####集群名稱cluster-name: myes####地址 cluster-nodes: 192.168.212.xxx:9300

三、實體類UserEntity

@Document(indexName = "mymayikt", type = "user") @Data public class UserEntity {@Idprivate String id;private String name;private int sex;private int age; }

四、dao層代碼（實現CrudRepository就可以了，里面封裝很多操作ES的方法）

public interface UserReposiory extends CrudRepository<UserEntity, String> {}

五、controller層

@RestController public class EsController {@Autowiredprivate UserReposiory userReposiory;@RequestMapping("/addUser")public UserEntity addUser(@RequestBody UserEntity user) {return userReposiory.save(user);}@RequestMapping("/findUser")public Optional<UserEntity> findUser(String id) {return userReposiory.findById(id);} }

六、啟動類

@SpringBootApplication @EnableElasticsearchRepositories(basePackages = "com.dyh.dao") public class AppEs {public static void main(String[] args) {SpringApplication.run(AppEs.class, args);} }

?

直接啟動會報錯：

None of the configured nodes are available:

　　解決方案（項目配置文件cluster-name要與ElasticSearch的配置文件屬性值要相同）:

　　　　Vi?/usr/local/elasticsearch-6.4.3/config/elasticsearch.yml

　　　　cluster.name: myes
