Spring Data Solr简介
虽然支持任何编程语言的能力具有很大的市场价值，你可能感兴趣的问题是：我如何将Solr的应用集成到Spring中？可以，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。
简单案例：
pom.xml
<dependencies>
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-solr</artifactId>
<version>1.5.5.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-test</artifactId>
<version>4.2.4.RELEASE</version>
</dependency>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.9</version>
</dependency>
</dependencies>
在src/main/resources下创建 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: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"> <!-- solr服务器地址 -->
<solr:solr-server id="solrServer" url="http://192.168.44.35:8080/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>
如果连的是solrCloud集群:
<!-- solr服务器地址
<solr:solr-server id="solrServer" url="http://192.168.44.35:8080/solr" />
-->
<bean id="solrServer" class="org.apache.solr.client.solrj.impl.CloudSolrServer">
<constructor-arg value="192.168.25.140:2181,192.168.25.140:2182,192.168.25.140:2183" />
<property name="defaultCollection" value="collection1"></property>
</bean>
@Field 注解
public class TestBean implements Serializable {
// @Field 用来指定那些成员属性是document的字段的
@Field
private String id;
@Field("title")
private String title;
@Field("content")
private String content;
@Field("name")
private String name;
//getter and setters
}使用spring data solr执行CURD
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations="classpath:applicationContext-solr.xml")
public class TestTemplate { @Autowired
private SolrTemplate solrTemplate; //添加
@Test
public void testAdd(){
TestBean item=new TestBean();
item.setId("1");
item.setTitle("testTitle");
item.setContent("testContent");
item.setName("testName");
solrTemplate.saveBean(item);
solrTemplate.commit();
}
//根据id删除
@Test
public void testDelete(){
solrTemplate.deleteById("1");
solrTemplate.commit();
}
//分页查询
@Test
public void testPageQuery(){
Query query=new SimpleQuery("*:*");
query.setOffset(20);//开始索引（默认0）
query.setRows(20);//每页记录数(默认10)
ScoredPage<TestBean> page = solrTemplate.queryForPage(query, TestBean.class);
System.out.println("总记录数："+page.getTotalElements());
List<TestBean> list = page.getContent();
showList(list);
}
//显示记录数据
private void showList(List<TestBean> list){
for(TestBean item:list){
System.out.println(item.getTitle());
}
}
//条件查询
@Test
public void testPageQueryMutil(){
Query query=new SimpleQuery("*:*");
Criteria criteria=new Criteria("title").contains("2");
criteria=criteria.and("title").contains("5");
query.addCriteria(criteria);
//query.setOffset(20);//开始索引（默认0）
//query.setRows(20);//每页记录数(默认10)
ScoredPage<TestBean> page = solrTemplate.queryForPage(query, TestBean.class);
System.out.println("总记录数："+page.getTotalElements());
List<TestBean> list = page.getContent();
showList(list);
}
//删除全部
@Test
public void testDeleteAll(){
Query query=new SimpleQuery("*:*");
solrTemplate.delete(query);
solrTemplate.commit();
}
}
补充：模拟商品(sku) 查询 数据存放在solr中 查询相关条件放到redis做缓存
