Spring Data Solr入门小Demo

Spring Data Solr入门小Demo
搭建工程
(1)创建maven工程,pom.xml中引入依赖

   <dependencies>
    <dependency>
        <groupId>org.springframework.datagroupId>
        <artifactId>spring-data-solrartifactId>
        <version>1.5.5.RELEASEversion>
    dependency> 
    <dependency>
        <groupId>org.springframeworkgroupId>
        <artifactId>spring-testartifactId>
        <version>4.2.4.RELEASEversion>
    dependency>
    <dependency>
        <groupId>junitgroupId>
        <artifactId>junitartifactId>
        <version>4.9version>
    dependency>
  dependencies>

(2)在src/main/resources下创建 applicationContext-solr.xml


<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:solr-server id="solrServer" url="http://127.0.0.1:8080/solr" />
    
    <bean id="solrTemplate" class="org.springframework.data.solr.core.SolrTemplate">
        <constructor-arg ref="solrServer" />
    bean>
beans>

@Field 注解
创建 cn.itcast.pojo 包,将品优购的TbItem实体类拷入本工程 ,属性使用@Field注解标识 。 如果属性与配置文件定义的域名称不一致,需要在注解中指定域名称。

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;
.......
}

增加(修改)
创建测试类TestTemplate.java

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations="classpath:applicationContext-solr.xml")
public class TestTemplate {

    @Autowired
    private SolrTemplate solrTemplate;

    @Test
    public void testAdd(){
        TbItem item=new TbItem();
        item.setId(1L);
        item.setBrand("华为");
        item.setCategory("手机");
        item.setGoodsId(1L);
        item.setSeller("华为2号专卖店");
        item.setTitle("华为Mate9");
        item.setPrice(new BigDecimal(2000));        
        solrTemplate.saveBean(item);
        solrTemplate.commit();
    }
}

按主键查询

    @Test
    public void testFindOne(){
        TbItem item = solrTemplate.getById(1, TbItem.class);
        System.out.println(item.getTitle());
    }

按主键删除

@Test
    public void testDelete(){
        solrTemplate.deleteById("1");
        solrTemplate.commit();
    }

分页查询
首先循环插入100条测试数据

@Test
    public void testAddList(){
        List list=new ArrayList();

        for(int i=0;i<100;i++){
            TbItem item=new TbItem();
            item.setId(i+1L);
            item.setBrand("华为");
            item.setCategory("手机");
            item.setGoodsId(1L);
            item.setSeller("华为2号专卖店");
            item.setTitle("华为Mate"+i);
            item.setPrice(new BigDecimal(2000+i));  
            list.add(item);
        }

        solrTemplate.saveBeans(list);
        solrTemplate.commit();
    }

编写分页查询测试代码:

@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 page = solrTemplate.queryForPage(query, TbItem.class);
        System.out.println("总记录数:"+page.getTotalElements());
        List list = page.getContent();
        showList(list);
    }   
    //显示记录数据
    private void showList(List list){       
        for(TbItem item:list){
            System.out.println(item.getTitle() +item.getPrice());
        }       
    }

条件查询
Criteria 用于对条件的封装:

@Test
    public void testPageQueryMutil(){   
        Query query=new SimpleQuery("*:*");
        Criteria criteria=new Criteria("item_title").contains("2");
        criteria=criteria.and("item_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 page = solrTemplate.queryForPage(query, TbItem.class);
        System.out.println("总记录数:"+page.getTotalElements());
        List list = page.getContent();
        showList(list);
    }

删除全部数据

@Test
    public void testDeleteAll(){
        Query query=new SimpleQuery("*:*");
        solrTemplate.delete(query);
        solrTemplate.commit();
    }
