es与springboot整合，Kibana 版本下载

kibana与es版本号要保持一致:

https://artifacts.elastic.co/downloads/kibana/kibana-6.2.1-windows-x86_64.zip

https://artifacts.elastic.co/downloads/kibana/kibana-5.6.11-linux-x86_64.tar.gz

es在与springboot整合的时候经常报找不到es的节点的问题。有以下两步操作

network.host: 0.0.0.0
transport.tcp.port: 9300
http.port: 9200

将网络设置访问为都可以。

最关键的点是要查看

spring-data-elasticsearch包下引入的是es的哪个版本，
需要将这两个版本对应上，包括kibana版本都需要同一个版本号

引入的pom

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

    <groupId>com.google.code.gson</groupId>
    <artifactId>gson</artifactId>
    <version>2.8.2</version>
</dependency>


controller:

@RestController
@RequestMapping("/es")
public class ElasticSearchController {

    @Autowired
    private EmployeeRepository er;

    //增加
    @RequestMapping("/add/{id}")
    public String add(@PathVariable("id")String id){

        Employee employee=new Employee();
        employee.setId(id);
        employee.setFirstName("Y.S.K");
        employee.setLastName("~");
        employee.setAge(26);
        employee.setAbout("");
        er.save(employee);

        System.err.println("add a obj");

        return "success";
    }

    //删除
    @RequestMapping("/delete")
    public String delete(){
        Employee employee=new Employee();
        employee.setId("1");
        er.delete(employee);

        return "success";
    }

    //局部更新
    @RequestMapping("/update")
    public String update(){

        Employee employee=er.queryEmployeeById("1");
        employee.setFirstName("哈哈");
        er.save(employee);

        System.err.println("update a obj");

        return "success";
    }

    //查询
    @RequestMapping("/query/{id}")
    public Employee query(@PathVariable("id")String id){

        Employee accountInfo=er.queryEmployeeById(id);
        System.err.println(new Gson().toJson(accountInfo));

        return accountInfo;
    }

}

EmployeeRepository:

@Component
public interface EmployeeRepository extends ElasticsearchRepository<Employee,String> {
    Employee queryEmployeeById(String id);
}
实体类：

@Data
@Document(indexName = "megacorp",type = "employee")
public class Employee {
    @Id
    private String id;
    private String firstName;
    private String lastName;

    private Integer age = 0;
    private String about;
}

yml:

spring:
  data:
    elasticsearch:
      cluster-name: elasticsearch
      cluster-nodes:  192.168.6.22:9300
      repositories:
        enabled: true
