全文搜索引擎——Solr

1.部署solr

  a.下载并解压Solr

  b.导入项目(独立项目):

    将解压后的 server\solr-webapp 下的 webapp文件夹 拷贝到tomcat的webapps下,并重命名为 solr

  c.加入jar包 及 log4j配置:

    将解压后的 server\lib\ext 下的所有 jar包 拷贝到 tomcat下solr项目的 lib中

    将解压后的 server\lib 下的所有 metrics 开头的 jar包 拷贝到 tomcat下solr项目的 lib中

    将解压后的 dist 下的 solr-dataimporthandler-7.2.1.jar 和 solr-dataimporthandler-extras-7.2.1.jar 也拷贝到 tomcat下solr项目的 lib中

    将解压后的 server\resources 下的  log4j.properties  拷贝到 tomcat下solr项目的 WEB-INF\classes 中

  d.创建solrHome

    将解压的 server 下的 solr 文件夹 拷贝出来(根据自己情况拷贝到常用工具文件夹中),并重命名(solrHome7\solrHome)

  e.修改web.xml 指向 solrHome

    修改tomcat下solr项目中的web.xml,并注释掉<security-constraint>

    <env-entry>
       <env-entry-name>solr/home</env-entry-name>
       <env-entry-value>D:\JavaTools\solrHome7\solrHome</env-entry-value>
       <env-entry-type>java.lang.String</env-entry-type>
    </env-entry>
  <!-- Get rid of error message -->
  <!-- <security-constraint>
    <web-resource-collection>
      <web-resource-name>Disable TRACE</web-resource-name>
      <url-pattern>/</url-pattern>
      <http-method>TRACE</http-method>
    </web-resource-collection>
    <auth-constraint/>
  </security-constraint>
  <security-constraint>
    <web-resource-collection>
      <web-resource-name>Enable everything but TRACE</web-resource-name>
      <url-pattern>/</url-pattern>
      <http-method-omission>TRACE</http-method-omission>
    </web-resource-collection>
  </security-constraint> -->

  f.现在就可以开启tomcat 访问 localhost:8080/solr/index.html 打开Solr管理界面了

2.solr 配置数据库连接导入数据

  a.将解压后的 contrib 和 dist 两文件夹 拷贝到 solrHome7 下与 solrHome 放在一起

  b.在 contrib\dataimporthandler 下新建 lib 文件夹,并将 solr-dataimporthandler-7.2.1.jar (上文1-c中jar包)拷入其中

  c.在 contrib 下新建 bd 文件夹,再在bd文件中新建 lib 文件夹,并将 常规数据库连接包(mysql-connector-java-5.1.39-bin.jar)拷入其中

  d.新建core1实例

    在solrHome7\solrHome 中新建文件夹 core1 文件夹

    将solrHome7\solrHome/configsets/sample_techproducts_configs 下的 conf 文件夹 复制到solrHome7\solrHome\core1中

  e.在 conf 文件夹中新建 data-config.xml

<dataConfig>
    <!-- 这是mysql的配置 -->
    <dataSource type="JdbcDataSource" driver="com.mysql.jdbc.Driver" url="jdbc:mysql://localhost:3306/blog" user="root" password="1452"/>
    <document>
        <!-- name属性,就代表着一个文档,可以随便命名 -->
        <!-- query是一条sql,代表在数据库查找出来的数据 -->
        <entity name="article" query="select * from article">
            <!-- 每一个field映射着数据库中列与文档中的域,column是数据库列,name是solr的域(必须是在managed-schema文件中配置过的域才行) -->
            <field column="article_id" name="article_id"/>
            <field column="article_title" name="article_title"/>
            <field column="article_content" name="article_content"/>
            <field column="user_id" name="user_id"/>
            <field column="article_type" name="article_type"/>
            <field column="edit_date" name="edit_date"/>
            <field column="read_num" name="read_num"/>
            <field column="article_summary" name="article_summary"/>
        </entity>
    </document>
</dataConfig>

  f.在 conf 文件夹中修改 solrconfig.xml

  <lib dir="${solr.install.dir:../../../..}/contrib/dataimporthandler/lib" regex=".*\.jar" />
  <lib dir="${solr.install.dir:../../../..}/contrib/db/lib" regex=".*\.jar" />
    <requestHandler name="/dataimport" class="org.apache.solr.handler.dataimport.DataImportHandler">
      <lst name="defaults">
            <str name="config">data-config.xml</str>
      </lst>
    </requestHandler>

  g.在 conf 文件夹中修改 managed-schema

<?xml version="1.0" encoding="UTF-8" ?>

<!--
 This is the Solr schema file. This file should be named "schema.xml" and
 should be in the conf directory under the solr home
 (i.e. ./solr/conf/schema.xml by default)
 or located where the classloader for the Solr webapp can find it.

 This example schema is the recommended starting point for users.
 It should be kept correct and concise, usable out-of-the-box.

 For more information, on how to customize this file, please see
 http://wiki.apache.org/solr/SchemaXml

 PERFORMANCE NOTE: this schema includes many optional features and should not
 be used for benchmarking.  To improve performance one could
  - set stored="false" for all fields possible (esp large fields) when you
    only need to search on the field but don‘t need to return the original
    value.
  - set indexed="false" if you don‘t need to search on the field, but only
    return the field as a result of searching on other indexed fields.
  - remove all unneeded copyField statements
  - for best index size and searching performance, set "index" to false
    for all general text fields, use copyField to copy them to the
    catchall "text" field, and use that for searching.
  - For maximum indexing performance, use the ConcurrentUpdateSolrServer
    java client.
  - Remember to run the JVM in server mode, and use a higher logging level
    that avoids logging every request

           Kuromoji has a search mode (default) that does segmentation useful for search.  A heuristic
           is used to segment compounds into its parts and the compound itself is kept as synonym.

           Valid values for attribute mode are:
              normal: regular segmentation
              search: segmentation useful for search with synonyms compounds (default)
            extended: same as search mode, but unigrams unknown words (experimental)

           For some applications it might be good to use search mode for indexing and normal mode for
           queries to reduce recall and prevent parts of compounds from being matched and highlighted.
           Use <analyzer type="index"> and <analyzer type="query"> for this and mode normal in query.

           Kuromoji also has a convenient user dictionary feature that allows overriding the statistical
           model with your own entries for segmentation, part-of-speech tags and readings without a need
           to specify weights.  Notice that user dictionaries have not been subject to extensive testing.

           User dictionary attributes are:
                     userDictionary: user dictionary filename
             userDictionaryEncoding: user dictionary encoding (default is UTF-8)

           See lang/userdict_ja.txt for a sample user dictionary file.

           Punctuation characters are discarded by default.  Use discardPunctuation="false" to keep them.

    <!-- Similarity is the scoring routine for each document vs. a query.

</schema>

    注:_version_, _root_, _text_ 这三个字段是solr默认字段,不建议删除;text 字段则是demo中solrconfig.xml内的默认字段,删了会报错,若要删除需修改solrconfig.xml

  h.访问 localhost:8080/solr/index.html 打开Solr管理界面

    在Core Admin中添加core1实例

    在Core Selector中选择core1,再在DataImport中点击Execute导入数据库数据,点击Refresh Status刷新后,若右侧Added/Updated数量符合则成功导入

3.Solr整合Spring

  a.导入依赖

    <!--solr客户端solrj的依赖 -->
    <dependency>
        <groupId>org.apache.solr</groupId>
        <artifactId>solr-solrj</artifactId>
        <version>5.3.1</version>
    </dependency>

  b.新建 spring-solr.xml 和 solr.properties

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xmlns:context="http://www.springframework.org/schema/context"
        xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans-4.3.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context-4.3.xsd">

    <!--定义solr的server-->
    <bean id="httpSolrServer" class="org.apache.solr.client.solrj.impl.HttpSolrServer">
        <constructor-arg index="0" value="${solr.url}"/>
        <!-- 设置响应解析器 -->
        <property name="parser">
            <bean class="org.apache.solr.client.solrj.impl.XMLResponseParser"/>
        </property>
        <!-- 设置重试次数-->
        <property name="maxRetries" value="${solr.maxRetries}"/>
        <!-- 建立连接的最长时间 -->
        <property name="connectionTimeout" value="${solr.connectionTimeout}"/>
    </bean>

</beans>
solr.url=http://localhost:8080/solr
solr.maxRetries=1
solr.connectionTimeout=500 

  c.在service中查询结果

    public List<Article> showArticlesByKeyWord(String keyWord){
        keyWord = "*" + keyWord + "*";

        //从solr中获取数据
        HttpSolrClient client = new HttpSolrClient(IConstant.SOLR_CORE_URL);
        SolrQuery query = new SolrQuery();
        query.set("q", "article_title:" + keyWord);
        query.set("sort", "edit_date desc");

        List<Article> articleList = new ArrayList<Article>();
        try {
            QueryResponse queryResponse = client.query(query);
            SolrDocumentList resultList = queryResponse.getResults();
            for(SolrDocument solrDocument : resultList){
                Article article = new Article();
                article.setArticleId(String.valueOf(solrDocument.get("article_id")));
                article.setArticleTitle(String.valueOf(solrDocument.get("article_title")));
                article.setArticleContent(String.valueOf(solrDocument.get("article_content")));
                article.setUserId(String.valueOf(solrDocument.get("user_id")));
                article.setArticleType(Integer.valueOf(String.valueOf(solrDocument.get("article_type"))));
                article.setEditDate(new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(((Date)(solrDocument.get("edit_date")))));
                article.setReadNum(Integer.valueOf(String.valueOf(solrDocument.get("read_num"))));
                article.setArticleSummary(String.valueOf(solrDocument.get("article_summary")));
                articleList.add(article);
            }

        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        return articleList;
    }

  d.新建工具类,导入数据库数据(需要引入HttpClient依赖)

public class SolrUtil {

    public static void importData(){
        CloseableHttpClient httpClient = HttpClients.createDefault();
        try {
            URIBuilder builder = new URIBuilder("http://localhost:8080/solr/core1/dataimport?command=full-import");
            URI uri = builder.build();
            HttpGet httpGet = new HttpGet(uri);
            httpClient.execute(httpGet);

        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

全文搜索引擎——Solr的相关文章

电商论道---(2)Solr全文搜索引擎的准备工作

Solr是一个基于Lucene的全文搜索引擎,提供了更丰富的搜索语言,更灵活的配置,更高的查询效率.一句话,与Lucene相比,有过之而无不及.这一节里, 主要谈论两个知识点:Jdk的安装和Tomcat的安装. Solr服务器端使用的是JAVA,所以我们需要安装这两个软件. 有朋友可能说,安装这两个软件就不用讲了吧,其实不然, 对于.NET的同学来说,他们对这两个软件比较陌生. 首先要安装JDK,然后再安装Tomcat,按顺序安装 1.JDK的安装 1.1下载地址:http://www.orac

全文搜索引擎 ElasticSearch 还是 Solr?

最近项目组安排了一个任务,项目中用到了全文搜索,基于全文搜索 Solr,但是该 Solr 搜索云项目不稳定,经常查询不出来数据,需要手动全量同步,而且是其他团队在维护,依赖性太强,导致 Solr 服务一出问题,我们的项目也基本瘫痪,因为所有的依赖查询都无结果数据了.所以考虑开发一个适配层,如果 Solr 搜索出问题,自动切换到新的搜索--ES. 其实可以通过 Solr 集群或者服务容错等设计来解决该问题.但是先不考虑本身设计的合理性,领导需要开发,所以我开始踏上了搭建 ES 服务的道路,从零开始

搜索引擎solr和elasticsearch

刚開始接触搜索引擎,网上收集了一些资料.在这里整理了一下分享给大家. 一.关于搜索引擎 搜索引擎(Search Engine)是指依据一定的策略.运用特定的计算机程序从互联网上搜集信息.在对信息进行组织和处理后,为用户提供检索服务.将用户检索相关的信息展示给用户的系统. 搜索引擎包含全文索引.文件夹索引.元搜索引擎.垂直搜索引擎.集合式搜索引擎.门户搜索引擎与免费链接列表等. 一个搜索引擎由搜索器 .索引器 .检索器 和用户接口 四个部分组成.搜索器的功能是在互联网 中漫游,发现和搜集信息.索引

全文搜索引擎Elasticsearch初探

前言: 在Web应用或后台数据管理中,随着数据量的倍数增长,搜索引擎特别是全文搜索引擎的应用越来越迫切.基于技术和成本考虑,我们不可能去开发一个搜索引擎以满足我们的需求,庆幸的是业界已有许多优秀的开源搜索引擎可供我们使用,Elasticsearch便是其中之一. 简介: Elasticsearch是一个基于Apache Lucene(TM)的开源搜索引擎.无论在开源还是专有领域,Lucene可以被认为是迄今为止最先进.性能最好的.功能最全的搜索引擎库.但是,Lucene只是一个库.想要使用它,你
