SpringBoot之整合elasticsearch

环境：

ES5.5

SpringBoot2.0.0

整合方式采用 spring-data-elasticsearch

增加maven

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

application.yml

spring:
    data:
        elasticsearch:
          cluster-name: my_cluster #es安装时配置的集群名称
          cluster-nodes: 192.168.111.129:9300 #配置es节点信息，多个逗号分隔

实体类

import org.springframework.data.annotation.Id;
import org.springframework.data.elasticsearch.annotations.Document;
import java.io.Serializable;

/**
 * indexName:索引名  类似数据库名
 * type:类型 类似表名
 */
@Document(indexName = "zns", type = "book")
public class Book implements Serializable {
    @Id
    String id;
    String name;
    String author;

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getAuthor() {
        return author;
    }

    public void setAuthor(String author) {
        this.author = author;
    }
}
