1. 添加依赖

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

2 添加配置

此处使用rest方式操作es。除此还有 spring.elasticsearch.jest 方式可选择

# es配置
spring.elasticsearch.rest.uris=http://localhost:9200
spring.elasticsearch.rest.connection-timeout=1s
spring.elasticsearch.rest.read-timeout=30s

3 创建ES document映射

3.1 document映射类

package com.example.demo.es;

import org.springframework.data.elasticsearch.annotations.Document;
import org.springframework.data.elasticsearch.annotations.Field;
import org.springframework.data.elasticsearch.annotations.FieldType;

import javax.persistence.Id;

/**
 * @author Aaron
 * @date 2020/3/8
 */
@Document(indexName = "index_test", type = "type_user", shards = 1, replicas = 1)
public class UserDO {

    @Id
    @Field(type = FieldType.Keyword)
    private Integer id;

    // ik_max_word：会将文本做最细粒度的拆分
    // ik_smart：会将文本做最粗粒度的拆分
    @Field(type = FieldType.Text, analyzer = "ik_max_word", searchAnalyzer = "ik_max_word")
    private String name;

    @Field(type = FieldType.Text, analyzer = "ik_smart", searchAnalyzer = "ik_smart")
    private String phone;

    @Field(type = FieldType.Text, analyzer = "ik_max_word", searchAnalyzer = "ik_max_word")
    private String address;

    public UserDO() {
    }

    public UserDO(Integer id, String name, String phone, String address) {
        this.id = id;
        this.name = name;
        this.phone = phone;
        this.address = address;
    }

    public Integer getId() {
        return id;
    }

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

    public String getName() {
        return name;
    }

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

    public String getPhone() {
        return phone;
    }

    public void setPhone(String phone) {
        this.phone = phone;
    }

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }
}

3.2 数据操作repository

package com.example.demo.es;

import org.springframework.data.repository.CrudRepository;

import java.util.List;

/**
 * @author Aaron
 * @date 2020/3/8
 */
public interface UserDORepository extends CrudRepository<UserDO, Long> {

    List<UserDO> findByName(String name);

    List<UserDO> findByPhone(String phone);

    List<UserDO> findByAddress(String address);
}

配置扫描Document映射类所在包

package com.example.demo.config;

import org.springframework.context.annotation.Configuration;
import org.springframework.data.elasticsearch.repository.config.EnableElasticsearchRepositories;

/**
 * @author Aaron
 * @date 2020/3/8
 */
@Configuration
@EnableElasticsearchRepositories(basePackages = "com.example.demo.es")
public class EsConfig {
}

3.3 Service、Controller 代码

package com.example.demo.es;

import org.springframework.data.elasticsearch.core.ElasticsearchRestTemplate;
import org.springframework.stereotype.Service;

import javax.annotation.Resource;
import java.util.List;

/**
 * @author Aaron
 * @date 2020/3/8
 */
@Service
public class UserEsService {
    @Resource
    private UserDORepository repository;
    @Resource
    private ElasticsearchRestTemplate elasticsearchTemplate;

    public void init() {
        elasticsearchTemplate.createIndex(UserDO.class);
        repository.deleteAll();
        UserDO user1 = new UserDO(1, "Tom", "13800138000", "广东省深圳市南山区");
        UserDO user2 = new UserDO(2, "Aaron", "13800138001", "北京市朝阳区");
        repository.save(user1);
        repository.save(user2);
    }

    public void save(UserDO user) {
        repository.save(user);
    }

    public List<UserDO> findByAddress(String address) {
        return repository.findByAddress(address);
    }
}

package com.example.demo.controller;

import com.example.demo.es.UserDO;
import com.example.demo.es.UserEsService;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import javax.annotation.Resource;
import java.util.List;

/**
 * @author Aaron
 * @date 2020/3/8
 */
@RestController
@RequestMapping("es")
public class EsController {

    @Resource
    private UserEsService userEsService;

    @GetMapping("init")
    public String init() {
        userEsService.init();
        return "success";
    }

    @GetMapping("save")
    public String save(UserDO user) {
        userEsService.save(user);
        return "success";
    }

    @GetMapping("findByAddress")
    public List<UserDO> findByAddress(String address) {
        return userEsService.findByAddress(address);
    }

}
