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
(1) 配置业务域
vim /usr/local/solr/solrhome/collection1/conf/schema.xml
<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" /> <field name="item_keywords" type="text_ik" indexed="true" stored="false" multiValued="true"/> <!-- 复制域 -->
<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"/> <!-- 动态域 --> <dynamicField name="item_spec_*" type="string" indexed="true" stored="true" />
(2) 引入相关依赖
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-solr</artifactId>
<version>1.5.5.RELEASE</version>
</dependency>
(3) 在相应pojo类中添加@Field注解
public class TbItem implements Serializable{ private static final long serialVersionUID = 1L; @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; @Field("item_updatetime") 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; @Dynamic @Field("item_spec_*") private Map<String,String> specMap;
(4) xml配置文件
<?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">
<context:component-scan base-package="com.xxx.solrUtil"></context:component-scan> <!-- solr服务器地址 --> <solr:solr-server id="solrServer" url="http://127.0.0.1:8081/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) 导入数据代码
@Component public class SolrUtil { @Autowired private TbItemMapper itemMapper; @Autowired private SolrTemplate solrTemplate; public void importItemData(){ TbItemExample example = new TbItemExample(); Criteria criteria = example.createCriteria(); criteria.andStatusEqualTo("1"); List<TbItem> list = itemMapper.selectByExample(example); System.out.println("---商品列表---"); for (TbItem tbItem : list) { System.out.println(tbItem.getId()+" "+ tbItem.getTitle()+ " "+tbItem.getPrice()); // 动态域数据 String spec = tbItem.getSpec(); // FastJSON的泛型 Map<String, String> map = JSON.parseObject(spec, new TypeReference<Map<String, String>>(){}); tbItem.setSpecMap(map); } solrTemplate.saveBeans(list); solrTemplate.commit(); System.out.println("---结束---"); }
}
(6) 高亮显示
// TODO 搜索关键字列表(关键字高亮) private Map<String, Object> searchList(Map<String, Object> searchMap) {
// ************************ 关键字 ************************
// 设置关键字搜索域(可以设置多个搜索域)
Criteria criteria = new Criteria("item_keywords");
criteria.is(searchMap.get("keywords"));
query.addCriteria(criteria);
// ************************ 条件过滤 ************************
FilterQuery filterQuery = new SimpleFilterQuery();
Criteria filterCriteria = new Criteria("item_title");
filterCriteria.is(searchMap.get(key));
filterQuery.addCriteria(filterCriteria);
query.addFilterQuery(filterQuery); // ************************ 高亮初始化 ************************ // 创建搜索对象(普通搜索) // Query query = new SimpleQuery("*:*"); // 创建搜索对象(高亮搜索) SimpleHighlightQuery query = new SimpleHighlightQuery(); // 设置高亮选项对象 HighlightOptions highlightOptions = new HighlightOptions(); highlightOptions.addField("item_title");// 设置高亮域 highlightOptions.setSimplePrefix("<span style=‘color: red;‘>");// 设置高亮前缀 highlightOptions.setSimplePostfix("</span>");// 设置高亮后缀 // 设置高亮选项 query.setHighlightOptions(highlightOptions);// 普通搜索 // ScoredPage<TbItem> page = solrTemplate.queryForPage(query, TbItem.class); // ************************ 获取高亮 ************************ // 所搜结果 HighlightPage<TbItem> page = solrTemplate.queryForHighlightPage(query, TbItem.class); List<HighlightEntry<TbItem>> highlightedResult = page.getHighlighted();// 高亮结果集 for (HighlightEntry<TbItem> entry : highlightedResult) { List<Highlight> highlightList = entry.getHighlights(); // 只设定一个搜索域,entry.getHighlights()只有1个值,highlightList.get(0).getSnipplets()也只有1个值 if (highlightList.size() > 0 && highlightList.get(0).getSnipplets().size() > 0) { // 设置高亮 TbItem tbItem = entry.getEntity(); tbItem.setTitle(highlightList.get(0).getSnipplets().get(0)); // System.out.println(tbItem.getId() + " " + tbItem.getTitle() + " " + tbItem.getPrice()); } } map.put("rows", page.getContent());// 搜索结果 map.put("totalPages", page.getTotalPages());// 总页数 map.put("total", page.getTotalElements());// 总记录数 System.out.println("rows: " + page.getContent() + ",totalPages: " + page.getTotalPages() + ",total: " + page.getTotalElements()); return map; }
(7) solrTemplate常用方法
1) 添加/修改
solrTemplate.saveBean(item);
2) 主键查询
Item item = solrTemplate.getById(1, Item.class);
3) 主键删除
solrTemplate.deleteById("1");
4) 分页
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<Item> page = solrTemplate.queryForPage(query, Item.class); List<Item> list = page.getContent();
5) 条件查询
Query query=new SimpleQuery("*:*"); Criteria criteria=new Criteria("item_title").contains("2"); criteria=criteria.and("item_title").contains("5"); query.addCriteria(criteria); ScoredPage<Item> page = solrTemplate.queryForPage(query, Item.class); List<TbItem> list = page.getContent();
6) 删除所有
Query query=new SimpleQuery("*:*"); solrTemplate.delete(query);
7) 提交(cud)
solrTemplate.commit();
8) 关于动态域搜索
item_spec_网络;item_spec_机身内存
spec = {‘key1‘:‘value1‘, ‘key2‘:‘value2‘};spec = {‘网络‘:‘value1‘, ‘机身内存‘:‘value2‘}
Map<String, String> spec = (Map<String, String>) searchMap.get("spec");
for (String key : spec.keySet()) {
String value = spec.get(key);
FilterQuery filterQuery = new SimpleFilterQuery();
Criteria filterCriteria = new Criteria("item_spec_" + key);
filterCriteria.is(value);
filterQuery.addCriteria(filterCriteria);
query.addFilterQuery(filterQuery);
}
