SpringBoot集成ElasticSearch(ES)

ElasticSearch环境搭建

���用docker-compose搭建，具体配置如下：

version: '3'# 网桥es -> 方便相互通讯networks:  es:services:  elasticsearch:    image: registry.cn-hangzhou.aliyuncs.com/zhengqing/elasticsearch:7.14.1      # 原镜像`elasticsearch:7.14.1`    container_name: elasticsearch             # 容器名为'elasticsearch'    restart: unless-stopped                           # 指定容器退出后的重启策略为始终重启，但是不考虑在Docker守护进程启动时就已经停止了的容器    volumes:                                  # 数据卷挂载路径设置,将本机目录映射到容器目录      - "./elasticsearch/data:/usr/share/elasticsearch/data"      - "./elasticsearch/logs:/usr/share/elasticsearch/logs"      - "./elasticsearch/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml"#      - "./elasticsearch/config/jvm.options:/usr/share/elasticsearch/config/jvm.options"      - "./elasticsearch/plugins/ik:/usr/share/elasticsearch/plugins/ik" # IK中文分词插件    environment:                              # 设置环境变量,相当于docker run命令中的-e      TZ: Asia/Shanghai      LANG: en_US.UTF-8      TAKE_FILE_OWNERSHIP: "true"  # 权限      discovery.type: single-node      ES_JAVA_OPTS: "-Xmx512m -Xms512m"      #ELASTIC_PASSWORD: "123456" # elastic账号密码    ports:      - "9200:9200"      - "9300:9300"    networks:      - es  kibana:    image: registry.cn-hangzhou.aliyuncs.com/zhengqing/kibana:7.14.1       # 原镜像`kibana:7.14.1`    container_name: kibana    restart: unless-stopped    volumes:      - ./elasticsearch/kibana/config/kibana.yml:/usr/share/kibana/config/kibana.yml    ports:      - "5601:5601"    depends_on:      - elasticsearch    links:      - elasticsearch    networks:      - es

部署

# 运行docker-compose -f docker-compose-elasticsearch.yml -p elasticsearch up -d# 运行后，给当前目录下所有文件赋予权限(读、写、执行)#chmod -R 777 ./elasticsearch

ES访问地址：ip地址:9200 默认账号密码：elastic/123456

kibana访问地址：ip地址:5601/app/dev_tools#/console 默认账号密码：elastic/123456

设置ES密码

# 进入容器docker exec -it elasticsearch /bin/bash# 设置密码-随机生成密码# elasticsearch-setup-passwords auto# 设置密码-手动设置密码elasticsearch-setup-passwords interactive# 访问curl 127.0.0.1:9200 -u elastic:123456

一、依赖

            springboot-demo        com.et        1.0-SNAPSHOT        4.0.0    elasticsearch                        org.springframework.boot            spring-boot-starter-data-elasticsearch                            org.springframework.boot            spring-boot-starter-web                            org.springframework.boot            spring-boot-starter-webflux                            com.alibaba            fastjson            ${fastjson.version}                            org.springframework.boot            spring-boot-starter-test            test                            io.projectreactor            reactor-test            test            

二、配置文件和启动类

# elasticsearch.yml 文件中的 cluster.namespring.data.elasticsearch.cluster-name=docker-cluster# elasticsearch 调用地址，多个使用“,”隔开spring.data.elasticsearch.cluster-nodes=127.0.0.1:9300#spring.data.elasticsearch.repositories.enabled=true#spring.data.elasticsearch.username=elastic#spring.data.elasticsearch.password=123456#spring.data.elasticsearch.network.host=0.0.0.0

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

三、document实体类

@Ducument(indexName = "orders",type = "product")@Mapping(mappingPath = "productIndex.json")//解决ik分词不能使用的问题public class ProductDocument implements Serializable{@Id    private String id;    //@Field(analyzer = "ik_max_word",searchAnalyzer = "ik_max_word")    private String productName;    //@Field(analyzer = "ik_max_word",searchAnalyzer = "ik_max_word")    private String productDesc;    private Date createTime;    private Date updateTime;    public String getId() {        return id;    }    public void setId(String id) {        this.id = id;    }    public String getProductName() {        return productName;    }    public void setProductName(String productName) {        this.productName = productName;    }    public String getProductDesc() {        return productDesc;    }    public void setProductDesc(String productDesc) {        this.productDesc = productDesc;    }    public Date getCreateTime() {        return createTime;    }    public void setCreateTime(Date createTime) {        this.createTime = createTime;    }    public Date getUpdateTime() {        return updateTime;    }    public void setUpdateTime(Date updateTime) {        this.updateTime = updateTime;    }}

四、Service接口以及实现类

public interface EsSearchService extends BaseSearchService{//保存void save(ProductDocument... productDocuments);//删除void delete(String id);//清空索引void deleteAll();//根据id查询ProductDocument getById(String id);//查询全部List getAll();}

@Servicepublic class EsSearchServiceImpl extends BaseSearchServiceImpl implements EsSearchService {private Logger log = LoggerFactory.getLogger(getClass());@Resourceprivate ElasticsearchTemplate elasticsearchTemplate;@Resourceprivate ProductDocumentRepository productDocumentRepository;@Override    public void save(ProductDocument ... productDocuments) {        elasticsearchTemplate.putMapping(ProductDocument.class);        if(productDocuments.length > 0){            /*Arrays.asList(productDocuments).parallelStream()                    .map(productDocumentRepository::save)                    .forEach(productDocument -> log.info("【保存数据】：{}", JSON.toJSONString(productDocument)));*/            log.info("【保存索引】：{}",JSON.toJSONString(productDocumentRepository.saveAll(Arrays.asList(productDocuments))));        }    }    @Override    public void delete(String id) {        productDocumentRepository.deleteById(id);    }    @Override    public void deleteAll() {        productDocumentRepository.deleteAll();    }    @Override    public ProductDocument getById(String id) {        return productDocumentRepository.findById(id).get();    }    @Override    public List getAll() {        List list = new ArrayList();        productDocumentRepository.findAll().forEach(list::add);        return list;    }}

五、repository

@Componentpublic interface ProductDocumentRepository extends ElasticsearchRepository {}

productIndex.json

{  "properties": {    "createTime": {      "type": "long"    },    "productDesc": {      "type": "text",      "analyzer": "ik_max_word",      "search_analyzer": "ik_max_word"    },    "productName": {      "type": "text",      "analyzer": "ik_max_word",      "search_analyzer": "ik_max_word"    },    "updateTime": {      "type": "long"    }  }}

六、测试

@RunWith(SpringRunner.class)@SpringBootTestpublic class EssearchApplicationTests {    private Logger log = LoggerFactory.getLogger(getClass());    @Autowired    private EsSearchService esSearchService;    @Test    public void save() {        log.info("【创建索引前的数据条数】：{}",esSearchService.getAll().size());        ProductDocument productDocument = ProductDocumentBuilder.create()                .addId(System.currentTimeMillis() + "01")                .addProductName("无印良品 MUJI 基础润肤化妆水")                .addProductDesc("无印良品 MUJI 基础润肤化妆水 高保湿型 200ml")                .addCreateTime(new Date()).addUpdateTime(new Date())                .builder();        ProductDocument productDocument1 = ProductDocumentBuilder.create()                .addId(System.currentTimeMillis() + "02")                .addProductName("荣耀 V10 尊享版")                .addProductDesc("荣耀 V10 尊享版 6GB+128GB 幻夜黑 移动联通电信4G全面屏游戏手机 双卡双待")                .addCreateTime(new Date()).addUpdateTime(new Date())                .builder();        ProductDocument productDocument2 = ProductDocumentBuilder.create()                .addId(System.currentTimeMillis() + "03")                .addProductName("资生堂(SHISEIDO) 尿素红罐护手霜")                .addProductDesc("日本进口 资生堂(SHISEIDO) 尿素红罐护手霜 100g/罐 男女通用 深层滋养 改善粗糙")                .addCreateTime(new Date()).addUpdateTime(new Date())                .builder();        esSearchService.save(productDocument,productDocument1,productDocument2);        log.info("【创建索引ID】:{},{},{}",productDocument.getId(),productDocument1.getId(),productDocument2.getId());        log.info("【创建索引后的数据条数】：{}",esSearchService.getAll().size());    }    @Test    public void getAll(){        esSearchService.getAll().parallelStream()                .map(JSON::toJSONString)                .forEach(System.out::println);    }    @Test    public void deleteAll() {        esSearchService.deleteAll();    }    @Test    public void getById() {        log.info("【根据ID查询内容】：{}", JSON.toJSONString(esSearchService.getById("154470178213401")));    }    @Test    public void query() {        log.info("【根据关键字搜索内容】：{}", JSON.toJSONString(esSearchService.query("无印良品荣耀",ProductDocument.class)));    }    @Test    public void queryHit() {        String keyword = "联通尿素";        String indexName = "orders";        List searchHits = esSearchService.queryHit(keyword,indexName,"productName","productDesc");        log.info("【根据关键字搜索内容，命中部分高亮，返回内容】：{}", JSON.toJSONString(searchHits));        //[{"highlight":{"productDesc":"无印良品 MUJI 基础润肤化妆水 高保湿型 200ml","productName":"无印良品 MUJI 基础润肤化妆水"},"source":{"productDesc":"无印良品 MUJI 基础润肤化妆水 高保湿型 200ml","createTime":1544755966204,"updateTime":1544755966204,"id":"154475596620401","productName":"无印良品 MUJI 基础润肤化妆水"}},{"highlight":{"productDesc":"荣耀 V10 尊享版 6GB+128GB 幻夜黑 移动联通电信4G全面屏游戏手机 双卡双待","productName":"荣耀 V10 尊享版"},"source":{"productDesc":"荣耀 V10 尊享版 6GB+128GB 幻夜黑 移动联通电信4G全面屏游戏手机 双卡双待","createTime":1544755966204,"updateTime":1544755966204,"id":"154475596620402","productName":"荣耀 V10 尊享版"}}]    }    @Test    public void queryHitByPage() {        String keyword = "联通尿素";        String indexName = "orders";        Page searchHits = esSearchService.queryHitByPage(1,1,keyword,indexName,"productName","productDesc");        log.info("【分页查询，根据关键字搜索内容，命中部分高亮，返回内容】：{}", JSON.toJSONString(searchHits));        //[{"highlight":{"productDesc":"无印良品 MUJI 基础润肤化妆水 高保湿型 200ml","productName":"无印良品 MUJI 基础润肤化妆水"},"source":{"productDesc":"无印良品 MUJI 基础润肤化妆水 高保湿型 200ml","createTime":1544755966204,"updateTime":1544755966204,"id":"154475596620401","productName":"无印良品 MUJI 基础润肤化妆水"}},{"highlight":{"productDesc":"荣耀 V10 尊享版 6GB+128GB 幻夜黑 移动联通电信4G全面屏游戏手机 双卡双待","productName":"荣耀 V10 尊享版"},"source":{"productDesc":"荣耀 V10 尊享版 6GB+128GB 幻夜黑 移动联通电信4G全面屏游戏手机 双卡双待","createTime":1544755966204,"updateTime":1544755966204,"id":"154475596620402","productName":"荣耀 V10 尊享版"}}]    }    @Test    public void deleteIndex() {        log.info("【删除索引库】");        esSearchService.deleteIndex("orders");    }}
