一，准备数据库
数据表结构
CREATE TABLE `app` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`app_name` varchar(255) NOT NULL DEFAULT '',
`score` decimal(10,5) NOT NULL DEFAULT '0.00000',
`downLoadNum` int(10) NOT NULL DEFAULT '0',
`top` int(10) NOT NULL DEFAULT '0',
`type` int(10) NOT NULL DEFAULT '1',
`update_date` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULT CHARSET=utf8mb4;

生成一些测试数据
因为我们需要使用mysql作为数据源，我们需要增加对mysql使用的jar包
> cd server/solr-webapp/webapp/WEB-INF/lib/
> wget http://pic.w-blog.cn/mysql-connector-java.jar

二、增加solr-core
PS：这里基础solr命令启动的程序并未基于tomcat进行配置，后续cloud集群会使用tomcat进配置
尝试增加一个core会提示找不到配置，复制一份默认的配置文件
> cp -r server/solr/configsets/_default server/solr/new_core
1
在solrconfig.xml 下添加以下配置，添加位置大约在 680行，SearchHandler 配置上面：
> vim server/solr/new_core/conf/solrconfig.xml
<!-- Request Handlers
http://wiki.apache.org/solr/SolrRequestHandler
Incoming queries will be dispatched to a specific handler by name
based on the path specified in the request.
If a Request Handler is declared with startup="lazy", then it will
not be initialized until the first request that uses it.
-->
<!-- add property -->
<requestHandler name="/dataimport" class="org.apache.solr.handler.dataimport.DataImportHandler">
<lst name="defaults">
<str name="config">data-config.xml</str>
</lst>
</requestHandler>
<!-- SearchHandler
http://wiki.apache.org/solr/SearchHandler
For processing Search Queries, the primary Request Handler
provided with Solr is "SearchHandler" It delegates to a sequent
of SearchComponents (see below) and supports distributed
queries across multiple shards

该文件的配置如下，连接的是mysql也支持其他的数据库
query：查询数据库表符合记录数据
deltaQuery：增量索引查询主键ID 注意这个只能返回ID字段
deltaImportQuery：增量索引查询导入的数据
> vim server/solr/new_core/conf/data-config.xml
<?xml version="1.0" encoding="UTF-8"?>
<dataConfig>
<dataSource name="source"
type="JdbcDataSource"
driver="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost:3306/appstore"
user="root"
password="123456"
/>
<document>
<entity name="app"
pk="id"
dataSource="source"
query="select * from app"
deltaImportQuery="select * from app where id = '${dih.delta.id}'"
deltaQuery="select id from app where update_date > '${dataimporter.last_index_time}' and type = 1">
<field column="id" name="id"/>
<field column="update_date" name="update_date"/>
</entity>
</document>
</dataConfig>

在这之后，需要配置managed-schema文件，与数据库进行映射，在117行附近，添加与数据库的映射，具体添加规则，不详细写了。
> vim server/solr/new_core/conf/managed-schema
<!-- add propertity -->
<field name="appName" type="string" indexed="true" stored="true" />
<field name="score" type="string" indexed="true" stored="true" />
<field name="downLoadNum" type="string" indexed="true" stored="true" />
<field name="top" type="string" indexed="true" stored="true" />
<field name="type" type="string" indexed="true" stored="true" />
<field name="update_date" type="string" indexed="true" stored="true" />

重启solr
> solr restart -force

再次增加core发现已经可以增加成功
初始化数据
初始化完成就可以进行查询了
如果修改了可以触发更新操作
当然也可以通过请求URL的方式进行数据更新，这里也方便索引的更新和程序相结合
http://172.16.3.148:8983/solr/new_core/dataimport?command=delta-import&clean=%20false&commit=true&wt=json&indent=true&verbose=false&optimize=false&debug=false

Solr搜索引擎 — 两种安装方式
阅读数 52
常常在业务开发中会遇到大列表的查询需求或者按照各项条件搜索内容，一般的做法往往都是数据库直接搞定，但是到了一定的程度只有这类需求会带来巨大的开销，一个表格中涉及到了5张表的数据，搜索要求从其中3张表的...
