倒排索引
傳統索引：
先載入全部內容，再內容遍歷，從而查詢到目標資訊。
缺點：查詢速度特別慢，而且隨著資料量的增大越來越大。
什麼是倒排索引？

lucene的缺點
使用lucene時只能夠為一些簡單的資料建立索引檔案。
要求為整個資料中的item資訊建立索引，並且能夠根據新境的資料建立新的索引。
缺點：lucene不能滿足這樣的需求
solr：
solr是企業級搜尋引擎伺服器，提供對java的很好支援。
1、能夠實現整庫的索引建立
2、能夠定期為新增的資料建立索引
3、solr提供了視覺化的控制頁面
4、提供了很多種的格式支援
solr伺服器安裝
1、配置環境：jdk1.8
修改jdk配置檔案 vim /etc/profile 。jdk1.7修改到1.8
讓環境配置生效：source /etc/profile
檢視環境是否成功配置：java -version
2、匯入solr安裝包
解壓
進入bin目錄
啟動服務 ./solr start
關閉服務 ./solr stop
重啟服務 ./solr restart
3、瀏覽器開啟solr控制檯
預設埠：8983
需要先在/usr/local/src/solr-5.2.1/server/solr檔案一首歌下建立3個資料夾：
mkdir jt/conf jt/data
匯入配置檔案
1、
DIH表示為資料表建立索引的工具
配置檔案位置：/usr/local/src/solr-5.2.1/server/solr/jt/conf

2、匯入jar包
位置：/usr/local/src/solr-5.2.1/server/solr-webapp/webapp/WEB-INF/lib
jar包名：ik-analyzer-5.3.0.jar
mysql-connector-java-5.1.28-bin.jar
solr-dataimporthandler-5.2.1.jar
solr-dataimporthandler-extras-5.2.1.jar
3、建立classes資料夾：/usr/local/src/solr-5.2.1/server/solr-webapp/webapp/WEB-INF/classes
新增ik分詞的配置檔案
檔案：ik_ext.dic 允許索引的詞，自定義
ik_stopwords.dic 禁止建立索引的詞，自定義
IKAnalyzer.cfg.xml 配置檔案
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE properties SYSTEM "http://java.sun.com/dtd/properties.dtd"> <properties> <comment>IK Analyzer 擴充套件配置</comment> <!--使用者可以在這裡配置自己的擴充套件字典 --> <entry key="ext_dict">ik_ext.dic;</entry> <!--使用者可以在這裡配置自己的擴充套件停止詞字典--> <entry key="ext_stopwords">ik_stopwords.dic;</entry> </properties>
4、匯入資料，建立索引
異常錯誤說明：
1、防火牆
2、需要開放mysql遠端訪問許可權 grant all privileges on *.* to root@'%' identified by "root";
java整合solr
1、整合spring配置檔案
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd"> <bean id="httpSolrServer" class="org.apache.solr.client.solrj.impl.HttpSolrServer"> <constructor-arg index="0" value="${SOLR.URL}"/> <!-- 設定響應解析器，solrj沒有提供json解析器，所以通常用xml解析器 --> <property name="parser"> <bean class="org.apache.solr.client.solrj.impl.XMLResponseParser"/> </property> <!-- 設定重試次數，推薦設定為1 --> <property name="maxRetries" value="1"/> <!-- 建立連線的最長時間 ,單位是：毫秒--> <property name="connectionTimeout" value="500"/> </bean> </beans>
2、url配置檔案solr.properties
SOLR.URL=http://solr.jt.com/solr/jt
3、java程式碼
@Autowired private HttpSolrServer httpSolrServer; @Override public List<Item> findItemListByKey(String keyword) { //準備全文檢索的物件 SolrQuery querySolr = new SolrQuery(keyword); //實現分頁 querySolr.setStart(0); //起始位置 querySolr.setRows(20); //每次查詢數量 try {//獲取返回值物件 QueryResponse response = httpSolrServer.query(querySolr); List<Item> itemList = response.getBeans(Item.class); return itemList; } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } return null; }
4、需要注意：
//需要將item物件的屬性與solr的索引的屬性檔案一一對應
5、配置nginx和host
