SpringDataSolr入门

1 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。

2 Spring Data Solr入门小Demo

2.1 搭建工程

(1) 创建maven工程,pom.xml中引入依赖

 

    org.springframework.data
    spring-data-solr
    1.5.5.RELEASE


org.springframework
spring-test
4.2.4.RELEASE


junit
junit
4.12

  

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

"1.0" encoding="UTF-8"?>
"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">

"solrServer" url="http://192.168.188.128:8080/solr" />

"solrTemplate" class="org.springframework.data.solr.core.SolrTemplate">
ref="solrServer" />

2.2.2 @Field 注解 

创建 com.offfcn.pojo 包,将优乐选的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;
    private String sellPoint;
    @Field("item_price")
    private BigDecimal price;
    private Integer stockCount;
    private Integer num;
    private String barcode;
    @Field("item_image")
    private String image;
    private Long categoryid;
    private String status;
    private Date createTime;
    private Date updateTime;
    private String itemSn;
    private BigDecimal costPirce;
    private BigDecimal marketPrice;
    private String isDefault;
    @Field("item_goodsid")
    private Long goodsId;
    private String sellerId;
    private String cartThumbnail;
    @Field("item_category")
    private String category;
    @Field("item_brand")
    private String brand;
    private String spec;
    @Field("item_seller")
    private String seller;
}

2.2.3 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();
}
}

2.2.4 按主键查询

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

2.2.5 按主键删除

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

2.2.6 分页查

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());
}
}

2.2.7 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);
}

2.2.8 删除全部数据

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