一. 项目整合

1.1 pom文件依赖

	<parent>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-parent</artifactId>
		<version>2.1.3.RELEASE</version>
		<relativePath/> <!-- lookup parent from repository -->
	</parent>
		<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.projectlombok</groupId>
			<artifactId>lombok</artifactId>
			<optional>true</optional>
		</dependency>
	</dependencies>

1.2 application.yml配置

# es配置
spring:
  data:
    elasticsearch:
      #集群名称
      cluster-name: myes #这里的名字一定要和elasticsearch.yml中的一样
      #集群地址
      cluster-nodes: 101.37.146.240:9300

1.3 实体类层

/**
 * @author: hejr
 * @desc:
 * @date: 2019/4/10 14:35
 */
@Data
@Document(indexName = "hszsd", type = "user")
public class UserEntity {

    @Id
    private String id;

    private String name;

    private Integer sex;

    private Integer age;
}

1.4 Dao层

/**
 * @author: hejr
 * @desc:
 * @date: 2019/4/10 14:37
 */
@Component
public interface UserRepository extends CrudRepository<UserEntity, String> {

}

1.5 Controller层

/**
 * @author: hejr
 * @desc:
 * @date: 2019/4/10 14:37
 */
@RestController
@Slf4j
public class EsController {

    @Autowired
    private UserRepository userRepository;

    @RequestMapping("/addUser")
    public UserEntity addUser(UserEntity user) {
        return userRepository.save(user);
    }

    @RequestMapping("/findUser")
    public Optional<UserEntity> findUser(String id) {
        return userRepository.findById(id);
    }

}

1.6 启动类配置

@SpringBootApplication
@EnableElasticsearchRepositories(basePackages = "com.hejr.dao")
public class Es001Application {

	public static void main(String[] args) {
		SpringApplication.run(Es001Application.class, args);
	}

}

1.7 启动项目

报错以下错误：
None of the configured nodes are available
解决方案:
vim /usr/local/elk/elasticsearch-6.7.0/config/elasticsearch.yml
cluster.name: myes
在这里插入图片描述

1.8 9200和9300区别

9300端口： ES节点之间通讯使用
9200端口： ES节点和外部通讯使用

9300是TCP协议端口号，ES集群之间通讯端口号
9200端口号，暴露ES RESTful接口端口号
