Springboot2.x集成Elasticsearch实例讲解

一、引用Elasticsearch依赖

我们用的是Springboot2.2.5.RELEASE版本，下面我们引入了Elasticsearch的依赖。我们用了swagger，因此也加入的swagger的依赖。

<dependency>
   <groupId>io.springfox</groupId>
     <artifactId>springfox-swagger2</artifactId>
     <version>2.9.2</version>
 </dependency>
 <dependency>
     <groupId>io.springfox</groupId>
     <artifactId>springfox-swagger-ui</artifactId>
     <version>2.9.2</version>
 </dependency>
 <dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-elasticsearch</artifactId>
</dependency>

二、配置文件修改

application.yml增加elasticsearch的地址及开启swagger配置

spring:
  elasticsearch:
    rest:
      uris: http://192.168.22.2:9200

swagger:
  enabled: true
jwt:
  header: Authorization

三、创建相关类

3.1 主类

package com.test.es.estest;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class EstestApplication {

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

}

3.2 实体类

package com.test.es.estest.entity;

import lombok.Data;
import lombok.NoArgsConstructor;
import lombok.experimental.Accessors;
import org.springframework.data.annotation.Id;
import org.springframework.data.elasticsearch.annotations.Document;
import org.springframework.data.elasticsearch.annotations.Field;
import org.springframework.data.elasticsearch.annotations.FieldType;

@Data
@NoArgsConstructor
@Accessors(chain = true)
@Document(indexName =
