[Java知识库]spring boot 集成 ES +ik分词器

1.TransportClient

  <!--es-->
        <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>

public interface *****Respository extends ElasticsearchRepository<*****Vo, String> {
}

Repository接口的自动实现，包括对自定义查找器方法的支持。

2.RestClient

   <!--es-->
        <!-- https://mvnrepository.com/artifact/org.elasticsearch/elasticsearch -->
        <dependency>
            <groupId>org.elasticsearch</groupId>
            <artifactId>elasticsearch</artifactId>
            <version>6.8.10</version>
        </dependency>

        <!-- https://mvnrepository.com/artifact/org.springframework.data/spring-data-elasticsearch -->
        <dependency>
            <groupId>org.springframework.data</groupId>
            <artifactId>spring-data-elasticsearch</artifactId>
            <version>3.2.8.RELEASE</version>
        </dependency>

        <!-- https://mvnrepository.com/artifact/org.elasticsearch.client/elasticsearch-rest-high-level-client -->
        <dependency>
            <groupId>org.elasticsearch.client</groupId>
            <artifactId>elasticsearch-rest-high-level-client</artifactId>
            <version>6.8.10</version>
        </dependency>

@Configuration
public class ElasticsearchConf extends AbstractElasticsearchConfiguration {

    @Value("${es.endpoints}")
    String esIp;

    @Override
    public RestHighLevelClient elasticsearchClient() {
        return RestClients.create(ClientConfiguration.create(esIp)).rest();
    }

    @Bean
    @Override
    public EntityMapper entityMapper() {

        ElasticsearchEntityMapper entityMapper = new ElasticsearchEntityMapper(
                elasticsearchMappingContext(), new DefaultConversionService()
        );
        entityMapper.setConversions(elasticsearchCustomConversions());

        return entityMapper;
    }
}

es:
  endpoints: 192.168.1.12:9200

因为我用的是docker所以只做了docker相关笔记

1. 进入docker 容器

docker exec -it a70fda65d2ba /bin/bash

2. 安装es对应分词器版本（找了半天对应的版本）

./bin/elasticsearch-plugin install https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v6.8.10/elasticsearch-analysis-ik-6.8.10.zip
分词器及相关下载
https://elasticsearch.cn/download/

3. 查看安装的分词器
   
4. 退出/重启

exit
docker restart elasticsearch
