ElasticSearch介紹

ElasticSearch是一個(gè)基于Lucene的搜索服務(wù)器，其實(shí)就是對(duì)Lucene進(jìn)行封裝，提供了 REST API 的操作接口?ElasticSearch作為一個(gè)高度可拓展的開(kāi)源全文搜索和分析引擎，可用于快速地對(duì)大數(shù)據(jù)進(jìn)行存儲(chǔ)，搜索和分析。
ElasticSearch主要特點(diǎn)：分布式、高可用、異步寫(xiě)入、多API、面向文檔 。
ElasticSearch核心概念：近實(shí)時(shí)，集群，節(jié)點(diǎn)（保存數(shù)據(jù)），索引，分片（將索引分片），副本（分片可設(shè)置多個(gè)副本） 。它可以快速地儲(chǔ)存、搜索和分析海量數(shù)據(jù)。
ElasticSearch使用案例:維基百科、Stack Overflow、Github 等等。

SpringBoot整合Elasticsearch

在使用SpringBoot整合Elasticsearch?之前，我們應(yīng)該了解下它們之間對(duì)應(yīng)版本的關(guān)系。

Spring Boot Version (x)	Spring Data Elasticsearch Version (y)	Elasticsearch Version (z)
x <= 1.3.5	y <= 1.3.4	z <= 1.7.2*
x >= 1.4.x	2.0.0 <=y < 5.0.0**	2.0.0 <= z < 5.0.0**

這里我們使用的SpringBoot的版本是1.5.9，Elasticsearch的版本是2.3.5。

使用SpringBoot整合Elasticsearch，一般都是使用?SpringData?進(jìn)行封裝的，然后再dao層接口繼承ElasticsearchRepository?類(lèi)，該類(lèi)實(shí)現(xiàn)了很多的方法，比如常用的CRUD方法。

SpringData的使用

首先，在使用之前，先做好相關(guān)的準(zhǔn)備。

Maven的配置如下:

<dependency>
????????????<groupId>org.springframework.boot</groupId>
????????????<artifactId>spring-boot-starter-web</artifactId>
?????????????<version>1.5.9.RELEASE</version>
????????</dependency>
??<dependency>
????????????<groupId>org.springframework.boot</groupId>
????????????<artifactId>spring-boot-starter-data-elasticsearch</artifactId>
?????????????<version>1.5.9.RELEASE</version>
????????</dependency>

application.properties的配置

spring.data.elasticsearch.repositories.enabled?=?truespring.data.elasticsearch.cluster-nodes?=127.0.0.1\:9300

注: 9300 是 Java 客戶(hù)端的端口。9200 是支持 Restful HTTP 的接口。

更多的配置:

spring.data.elasticsearch.cluster-name?Elasticsearch?集群名。(默認(rèn)值:?elasticsearch)spring.data.elasticsearch.cluster-nodes?集群節(jié)點(diǎn)地址列表，用逗號(hào)分隔。如果沒(méi)有指定，就啟動(dòng)一個(gè)客戶(hù)端節(jié)點(diǎn)。spring.data.elasticsearch.propertie?用來(lái)配置客戶(hù)端的額外屬性。spring.data.elasticsearch.repositories.enabled?開(kāi)啟?Elasticsearch?倉(cāng)庫(kù)。(默認(rèn)值:true。)

代碼編寫(xiě)

實(shí)體類(lèi)

@Document(indexName?=?"userindex",?type?=?"user")
public?class?User?implements?Serializable{?????/**?????*??????*/
????private?static?final?long?serialVersionUID?=?1L;????/**?編號(hào)?*/
?????private?Long?id;?????/**?姓名?*/
?????private?String?name;?????
?????/**?年齡?*/
?????private?Integer?age;?????
?????/**?描述?*/??
?????private?String?description;?????
?????/**?創(chuàng)建時(shí)間?*/
?????private?String?createtm;????//?getter和setter?略｝

使用SpringData的時(shí)候，它需要在實(shí)體類(lèi)中設(shè)置indexName?和type?，如果和傳統(tǒng)型數(shù)據(jù)庫(kù)比較的話(huà)，就相當(dāng)于庫(kù)和表。需要注意的是indexName和type都必須是小寫(xiě)!!!

dao層

public?interface?UserDao?extends?ElasticsearchRepository<User,?Long>{}

dao層這里就比較簡(jiǎn)單了，只需繼承ElasticsearchRepository該類(lèi)就行了。其中主要的方法就是 save、delete和search。其中save方法相當(dāng)如insert和update，沒(méi)有就新增，有就覆蓋。delete方法主要就是刪除數(shù)據(jù)以及索引庫(kù)。至于search就是查詢(xún)了，包括一些常用的查詢(xún)，如分頁(yè)、權(quán)重之類(lèi)的。

Service層

@Servicepublic?class?UserServiceImpl?implements?UserService?{????@Autowired
????private?UserDao?userDao;????@Override
????public?boolean?insert(User?user)?{????????boolean?falg=false;????????try{
????????????userDao.save(user);
????????????falg=true;
????????}catch(Exception?e){
????????????e.printStackTrace();
????????}????????return?falg;
????}????@Override
????public?List<User>?search(String?searchContent)?{
??????????QueryStringQueryBuilder?builder?=?new?QueryStringQueryBuilder(searchContent);
??????????System.out.println("查詢(xún)的語(yǔ)句:"+builder);
??????????Iterable<User>?searchResult?=?userDao.search(builder);
??????????Iterator<User>?iterator?=?searchResult.iterator();
??????????List<User>?list=new?ArrayList<User>();??????????while?(iterator.hasNext())?{
????????????list.add(iterator.next());
??????????}???????return?list;
????}????
????
????
????@Override
????public?List<User>?searchUser(Integer?pageNumber,?Integer?pageSize,String?searchContent)?{?????????//?分頁(yè)參數(shù)
????????Pageable?pageable?=?new?PageRequest(pageNumber,?pageSize);
????????QueryStringQueryBuilder?builder?=?new?QueryStringQueryBuilder(searchContent);
????????SearchQuery?searchQuery?=?new?NativeSearchQueryBuilder().withPageable(pageable).withQuery(builder).build();
????????System.out.println("查詢(xún)的語(yǔ)句:"?+?searchQuery.getQuery().toString());
????????Page<User>?searchPageResults?=?userDao.search(searchQuery);????????return?searchPageResults.getContent();
????}????

????@Override
????public?List<User>?searchUserByWeight(String?searchContent)?{?????//?根據(jù)權(quán)重進(jìn)行查詢(xún)
????????FunctionScoreQueryBuilder?functionScoreQueryBuilder?=?QueryBuilders.functionScoreQuery()
????????????????.add(QueryBuilders.boolQuery().should(QueryBuilders.matchQuery("name",?searchContent)),
????????????????????ScoreFunctionBuilders.weightFactorFunction(10))
????????????????.add(QueryBuilders.boolQuery().should(QueryBuilders.matchQuery("description",?searchContent)),
????????????????????????ScoreFunctionBuilders.weightFactorFunction(100)).setMinScore(2);
????????System.out.println("查詢(xún)的語(yǔ)句:"?+?functionScoreQueryBuilder.toString());
????????Iterable<User>?searchResult?=?userDao.search(functionScoreQueryBuilder);
????????Iterator<User>?iterator?=?searchResult.iterator();
????????List<User>?list=new?ArrayList<User>();????????while?(iterator.hasNext())?{
????????????list.add(iterator.next());
????????}????????return?list;
????}
}

這里我就簡(jiǎn)單的寫(xiě)了幾個(gè)方法，其中主要的方法是查詢(xún)。查詢(xún)包括全文搜索，分頁(yè)查詢(xún)和權(quán)重查詢(xún)。其中需要說(shuō)明的是權(quán)重查詢(xún)這塊，權(quán)重的分值越高，查詢(xún)的結(jié)果也越靠前，如果沒(méi)有對(duì)其它的數(shù)據(jù)設(shè)置分值，它們默認(rèn)的分值就是1，如果不想查詢(xún)這些語(yǔ)句，只需使用setMinScore將其設(shè)為大于1即可。

代碼測(cè)試

調(diào)用接口進(jìn)行添加數(shù)據(jù)

新增數(shù)據(jù):

POST?http://localhost:8086/api/user{"id":1,"name":"張三","age":20,"description":"張三是個(gè)Java開(kāi)發(fā)工程師","createtm":"2018-4-25?11:07:42"}
{"id":2,"name":"李四","age":24,"description":"李四是個(gè)測(cè)試工程師","createtm":"1980-2-15?19:01:32"}
{"id":3,"name":"王五","age":25,"description":"王五是個(gè)運(yùn)維工程師","createtm":"2016-8-21?06:11:32"}

進(jìn)行全文查詢(xún)
請(qǐng)求

http://localhost:8086/api/user?searchContent=工程師

返回

[{"id":2,"name":"李四","age":14,"description":"李四是個(gè)測(cè)試工程師","createtm":?"1980-2-15?19:01:32"},
{"id":1,"name":"張三","age":20,"description":"張三是個(gè)Java開(kāi)發(fā)工程師",?"createtm":?"2018-4-25?11:07:42"},
{"id":3,"name":"王五","age":25,"description":"王五是個(gè)運(yùn)維工程師","createtm":?"2016-8-21?06:11:32"}]

進(jìn)行分頁(yè)查詢(xún)
請(qǐng)求

http://localhost:8086/api/user?pageNumber=0&pageSize=2&searchContent=工程師

返回

[{"id":2,"name":"李四","age":14,"description":"李四是個(gè)測(cè)試工程師"},{"id":1,"name":"張三","age":20,"description":"張三是個(gè)Java開(kāi)發(fā)工程師"}]

進(jìn)行權(quán)重查詢(xún)
請(qǐng)求

http://localhost:8086/api/user2?searchContent=李四

返回

[{"id":2,"name":"李四","age":24,"description":"李四是個(gè)測(cè)試工程師","createtm":"1980-2-15?19:01:32"}]

權(quán)重查詢(xún)打印的語(yǔ)句:

查詢(xún)的語(yǔ)句:{{??"function_score"?:?{????"functions"?:?[?{??????"filter"?:?{????????"bool"?:?{??????????"should"?:?{????????????"match"?:?{??????????????"name"?:?{????????????????"query"?:?"李四",????????????????"type"?:?"boolean"
??????????????}
????????????}
??????????}
????????}
??????},??????"weight"?:?10.0
????},?{??????"filter"?:?{????????"bool"?:?{??????????"should"?:?{????????????"match"?:?{??????????????"description"?:?{????????????????"query"?:?"李四",????????????????"type"?:?"boolean"
??????????????}
????????????}
??????????}
????????}
??????},??????"weight"?:?100.0
????}?],????"min_score"?:?2.0
??}
}

注:測(cè)試中，因?yàn)樵O(shè)置了setMinScore最小權(quán)重分為2的，所以無(wú)關(guān)的數(shù)據(jù)是不會(huì)顯示出來(lái)的。如果想顯示的話(huà)，在代碼中去掉即可。

新增完數(shù)據(jù)之后，可以在瀏覽器輸入:http://localhost:9200/_plugin/head/
然后點(diǎn)擊基本查詢(xún)，便可以查看添加的數(shù)據(jù)。如果想用語(yǔ)句查詢(xún)，可以將程序中控制臺(tái)打印的查詢(xún)語(yǔ)句粘貼到查詢(xún)界面上進(jìn)行查詢(xún)!

注:這里的ElasticSearch是我在windows上安裝的，并安裝了ES插件head，具體安裝步驟在文章末尾。

除了SpringData之外，其實(shí)還有其它的方法操作ElasticSearch的。
比如使用原生ElasticSearch的Api，使用TransportClient類(lèi)實(shí)現(xiàn)。
或者使用由Spring封裝，只需在Service層，進(jìn)行注入Bean即可。
示例:

@Autowired
?ElasticsearchTemplate?elasticsearchTemplate;

但是，上述方法中都有其局限性，也就是隨著ElasticSearch的版本變更，相關(guān)的Java API也在做不斷的調(diào)整，就是ElasticSearch服務(wù)端版本進(jìn)行更改之后，客戶(hù)端的代碼可能需要重新編寫(xiě)。
因此介紹一個(gè)相當(dāng)好用的第三方工具JestClient，它對(duì)ElasticSearch進(jìn)行封裝，填補(bǔ)了?ElasticSearch?HttpRest接口 客戶(hù)端的空白，它適用于ElasticSearch2.x以上的版本，無(wú)需因?yàn)?strong>ElasticSearch服務(wù)端版本更改而對(duì)代碼進(jìn)行更改！

JestClient

首先在Maven中添加如下依賴(lài):

????<dependency>
????????<groupId>io.searchbox</groupId>?
?????????<artifactId>jest</artifactId>
????????<version>5.3.3</version>
????</dependency>

然后編寫(xiě)相關(guān)的測(cè)試代碼。
代碼中的注釋?xiě)?yīng)該很完整，所以這里就不再對(duì)代碼過(guò)多的講述了。

注:測(cè)試之前先說(shuō)明下，本地windows系統(tǒng)安裝的是ElasticSearch版本是2.3.5，linux服務(wù)器上安裝的ElasticSearch版本是6.2。

測(cè)試結(jié)果

全文搜索

全文搜索查詢(xún)語(yǔ)句:{??"from"?:?0,??"size"?:?2,??"query"?:?{????"query_string"?:?{??????"query"?:?"工程師"
????}

新增完數(shù)據(jù)之后，我們可以上linux的?Kibana中進(jìn)行相關(guān)的查詢(xún)，查詢(xún)結(jié)果如下:

注:Kibana 是屬于ELK中一個(gè)開(kāi)源軟件。Kibana可以為 Logstash 和 ElasticSearch 提供的日志分析友好的 Web 界面，可以幫助匯總、分析和搜索重要數(shù)據(jù)日志。

上述代碼中測(cè)試返回的結(jié)果符合我們的預(yù)期。其中關(guān)于JestClient只是用到了很少的一部分，更多的使用可以查看JestClient的官方文檔。
