SpringDataSolr简介
如何将Solr的应用集成到Spring中?Spring Data Solr就是为了方便Solr的开发所研制的一个框架,其底层是对SolrJ(官方API)的封装。
入门程序:
1、在solr服务器下的webapps/solr/WEB-INF/lib加入ik分词器的jar,等会会用到。

2、在solrhome\collection1\conf\schema.xml文件末尾 配置作用域:
<!-- 配置IK分词器 -->
<fieldType name="text_ik" class="solr.TextField">
<analyzer class="org.wltea.analyzer.lucene.IKAnalyzer"/>
</fieldType>
<!-- 配置业务域 -->
<field name="item_goodsid" type="long" indexed="true" stored="true"/>
<field name="item_title" type="text_ik" indexed="true" stored="true"/>
<field name="item_price" type="double" indexed="true" stored="true"/>
<field name="item_image" type="string" indexed="false" stored="true" />
<field name="item_category" type="string" indexed="true" stored="true" />
<field name="item_seller" type="text_ik" indexed="true" stored="true" />
<field name="item_brand" type="string" indexed="true" stored="true" />
<!-- 配置复制域 -->
<field name="item_keywords" type="text_ik" indexed="true" stored="false" multiValued="true"/>
<copyField source="item_title" dest="item_keywords"/>
<copyField source="item_category" dest="item_keywords"/>
<copyField source="item_seller" dest="item_keywords"/>
<copyField source="item_brand" dest="item_keywords"/>
<!-- 配置动态域 -->
<dynamicField name="item_spec_*" type="string" indexed="true" stored="true" />
3、创建一个普通的maven工程,引入依赖:
<dependencies>
<!--Spring整合solr框架坐标-->
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-solr</artifactId>
<version>1.5.5.RELEASE</version>
</dependency>
<!--Spring整合Junit单元测试-->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-test</artifactId>
</dependency>
<!--单元测试-->
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.9</version>
</dependency>
<!--引入dao工程-->
<dependency>
<groupId>com.soft</groupId>
<artifactId>legou_dao</artifactId>
<version>1.0-SNAPSHOT</version>
</dependency>
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>fastjson</artifactId>
</dependency>
</dependencies>
4、在resources下创建spirng/applicationContext-solr.xml:
<?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:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:solr="http://www.springframework.org/schema/data/solr"
xsi:schemaLocation="http://www.springframework.org/schema/data/solr
http://www.springframework.org/schema/data/solr/spring-solr-1.0.xsd
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd">
<!-- solr服务器地址 -->
<solr:solr-server id="solrServer" url="http://127.0.0.1:8090/solr" />
<!-- solr模板,使用solr模板可对索引库进行CRUD的操作 -->
<bean id="solrTemplate" class="org.springframework.data.solr.core.SolrTemplate">
<constructor-arg ref="solrServer" />
</bean>
</beans>
5、在实体类上添加@Field(“作用域名”)注解:
package cn.tx.domain;
import org.apache.solr.client.solrj.beans.Field;
import java.io.Serializable;
import java.math.BigDecimal;
import java.util.Date;
public class TbItem implements Serializable {
@Field
private Long id;
@Field("item_title")
private String title;
@Field("item_price")
private BigDecimal price;
@Field("item_image")
private String image;
@Field("item_goodsid")
private Long goodsId;
@Field("item_category")
private String category;
@Field("item_brand")
private String brand;
@Field("item_seller")
private String seller;
// get... set...
6、编写测试类:
package com.soft.test;
import com.soft.domain.TbItem;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.solr.core.SolrTemplate;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import java.math.BigDecimal;
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath*:spring/applicationContext*.xml")
public class SolrDemo1 {
// 注入SolrTemplate模板对象
@Autowired
private SolrTemplate solrTemplate;
/**
* 测试数据的添加
*/
@Test
public void testAdd(){
// 创建对象,添加数据
TbItem item = new TbItem();
item.setId(1L);
item.setBrand("华为");
item.setCategory("手机");
item.setGoodsId(1L);
item.setSeller("华为商家");
item.setTitle("华为标题");
item.setPrice(new BigDecimal(1999));
// 保存
solrTemplate.saveBean(item);
// 提交事务
solrTemplate.commit();
}
/**
* 测试修改
*/
@Test
public void testUpdate(){
TbItem item = new TbItem();
item.setId(1L);
item.setBrand("华为2");
item.setCategory("手机2");
item.setGoodsId(2L);
item.setSeller("华为商家2");
item.setTitle("华为标题2");
item.setPrice(new BigDecimal(1999));
// 修改
solrTemplate.saveBean(item);
// 提交事务
solrTemplate.commit();
}
/**
* 测试查询一条数据
*/
@Test
public void testFindOne(){
TbItem item = solrTemplate.getById(1L, TbItem.class);
System.out.println(item.getTitle());
}
/**
* 测试删除
*/
@Test
public void testDelete(){
solrTemplate.deleteById("1");
solrTemplate.commit();
}
/**
* 删除所有数据
*/
@Test
public void testDelAll(){
// 查询所有
SolrDataQuery query = new SimpleQuery("*:*");
solrTemplate.delete(query);
// 提交事务
solrTemplate.commit();
}
}
