Solr与数据库结合实现全文检索

来源：互联网发布：云计算格局编辑：程序博客网时间：2024/04/30 11:10

     一下给出了一个简单的实例展示了如何将Solr与数据库结合实现全文检索。生产环境下，会有很大差别，这里的配置仅作为调试或是开发所用。

1. 安装Java JDK 和Tomcat

第一步骤就是安装jdk 和Server 服务器Tomcat，这个也挺简单，这里就省略了。

2. 配置Solr Core

将Solr自带的一个例子复制一份，我这里演示的版本是Solr最新版本Solr 4.2.0.

修改需要与DB融合的shema.xml 和 solrconfig文件，修改细节如下：

假设目标表的结构如下所示：

可以这样来配置的schema.xml ：

    <!-- core  'customer' schema field definition -->   <field name="customer_id" type="int" indexed="true" stored="true" required="true"  multiValued="false"/>    <field name="name" type="string" indexed="true" stored="true"/>   <field name="sex" type="string" indexed="true" stored="false"/>   <field name="level" type="string" indexed="true" stored="true"/>   <field name="address" type="string" indexed="true" multiValued="true" stored="true"/>

修改uniqueKeys配置：

 <!-- Field to use to determine and enforce document uniqueness.       Unless this field is marked with required="false", it will be a required field      <uniqueKey>id</uniqueKey>   -->  <uniqueKey>customer_id</uniqueKey>

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 StreamingUpdateSolrServer    java client.  - Remember to run the JVM in server mode, and use a higher logging level    that avoids logging every request--><schema name="example" version="1.5">  <!-- attribute "name" is the name of this schema and is only used for display purposes.       version="x.y" is Solr's version number for the schema syntax and        semantics.  It should not normally be changed by applications.       1.0: multiValued attribute did not exist, all fields are multiValued             by nature       1.1: multiValued attribute introduced, false by default        1.2: omitTermFreqAndPositions attribute introduced, true by default             except for text fields.       1.3: removed optional field compress feature       1.4: autoGeneratePhraseQueries attribute introduced to drive QueryParser            behavior when a single string produces multiple tokens.  Defaults             to off for version >= 1.4       1.5: omitNorms defaults to true for primitive field types             (int, float, boolean, string...)     --> <fields>   <!-- Valid attributes for fields:     name: mandatory - the name for the field     type: mandatory - the name of a field type from the        <types> fieldType section     indexed: true if this field should be indexed (searchable or sortable)     stored: true if this field should be retrievable     docValues: true if this field should have doc values. Doc values are       useful for faceting, grouping, sorting and function queries. Although not       required, doc values will make the index faster to load, more       NRT-friendly and more memory-efficient. They however come with some       limitations: they are currently only supported by StrField, UUIDField       and all Trie*Fields, and depending on the field type, they might       require the field to be single-valued, be required or have a default       value (check the documentation of the field type you're interested in       for more information)     multiValued: true if this field may contain multiple values per document     omitNorms: (expert) set to true to omit the norms associated with       this field (this disables length normalization and index-time       boosting for the field, and saves some memory).  Only full-text       fields or fields that need an index-time boost need norms.       Norms are omitted for primitive (non-analyzed) types by default.     termVectors: [false] set to true to store the term vector for a       given field.       When using MoreLikeThis, fields used for similarity should be       stored for best performance.     termPositions: Store position information with the term vector.         This will increase storage costs.     termOffsets: Store offset information with the term vector. This        will increase storage costs.     required: The field is required.  It will throw an error if the       value does not exist     default: a value that should be used if no value is specified       when adding a document.   -->   <!-- field names should consist of alphanumeric or underscore characters only and      not start with a digit.

solrconfig.xml配置如下：

指定加载的jar包：

  <lib dir="../../../contrib/extraction/lib" regex=".*\.jar" />  <lib dir="../../../dist/" regex="solr-cell-\d.*\.jar" />  <lib dir="../../../contrib/clustering/lib/" regex=".*\.jar" />  <lib dir="../../../dist/" regex="solr-clustering-\d.*\.jar" />  <lib dir="../../../contrib/langid/lib/" regex=".*\.jar" />  <lib dir="../../../dist/" regex="solr-langid-\d.*\.jar" />  <lib dir="../../../contrib/velocity/lib" regex=".*\.jar" />  <lib dir="../../../dist/" regex="solr-velocity-\d.*\.jar" />  <lib dir="./lib/" regex=".*\.jar" />

将修要用到的jar包，"mysql-connection>*\.jar" 和导入依赖的“apache-solr-dataimporthandler.*\.jar”放在与config同级的目录下

  <requestHandler name="/dev/dataimport" class="org.apache.solr.handler.dataimport.DataImportHandler">    <lst name="defaults">      <str name="config">db-data-dev-config.xml</str>    </lst>  </requestHandler>

接下来，配置数据源文件db-data-dev-config.xml(与solrconfig.xml同一目录下)。

<dataConfig>    <dataSource type="JdbcDataSource" driver="com.mysql.jdbc.Driver" batchSize="-1" url="jdbc:mysql://localhost/pythondb?autoReconnect=true" user="elite" password="elite"/>    <document name="customer">         <entity name="customer"                 query="select c.* from customer c">                <field name="customer_id" column="id" /> </entity>    </document></dataConfig>

3. 配置Tomcat

在tomcat下建立一个指向Solr Core实例的Context，具体路径“conf\Catalina\localhost”下。比如，这里建立的文件名称是solr.xml。配置信息如下：

<?xml version="1.0" encoding="utf-8"?><Context docBase="F:/openSource/solr/solr-4.2.0/example-1/solr/solr-4.2.0.war">  <Environment name="solr/home" type="java.lang.String" value="F:/openSource/solr/solr-4.2.0/example-1/solr" override="true"/></Context>

必须将要用到的war包放到指定的位置，这个路径指定对了就好。

4. 运行服务

DOS环境下，进入到Tomcat的bin目录下，输入命令：startup.bat

接着道浏览器中具体的路径，得到如下结果证明配置基本正确。

最后，导入数据库中的数据，即根据数据库表中的数据建立索引。

直接在浏览器中输入：http://localhost:8088/solr/customer/dev/dataimport?command=full-import。

到控制太查看具体的结果，有如下结果证明配置成功。

数据库中的数据如下所示：
