目标1：完成solr环境安装、中文分析器和业务域的配置
目标2：会使用Spring Data Solr完成增删改查操作
目标3：完成批量数据导入功能
目标4：完成按关键字搜索功能
1.业务接口层
1 public interface ItemSearchService { 2 /** 3 * 搜索 4 * @param 5 * @return 6 */ 7 public Map<String,Object> search(Map searchMap); 8 }
2.服务实现层
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://192.168.188.128:8080/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>
在src/main/resources/spring 下applicationContext-service.xml ： dubbo端口20884
1 @Service(timeout = 3000) 2 public class ItemSearchServiceImpl2 implements ItemSearchService { 3 4 @Autowired 5 private SolrTemplate solrTemplate; 6 7 @Override 8 public Map<String, Object> search(Map searchMap) { 9 10 //获取查询条件 11 String keywords = String.valueOf(searchMap.get("keywords")); 12 Integer pageNo = Integer.parseInt(String.valueOf(searchMap.get("pageNo"))); 13 //获取每页查询条数 14 Integer pageSize = Integer.parseInt(String.valueOf(searchMap.get("pageSize"))); 15 16 17 Map<String,Object> resultMap=new HashMap<>(); 18 //封装查询对象 19 Query query=new SimpleQuery(); 20 //添加查询条件 21 Criteria criteria=new Criteria("item_keywords").is(searchMap.get("keywords")); 22 //将查询的条件放入查询的对象 23 query.addCriteria(criteria); 24 if (pageNo == null || pageNo <= 0){ 25 pageNo=1; 26 } 27 //当前页开始是第几条 28 Integer start = (pageNo-1)*pageSize; 29 //设置第几条开始 30 query.setOffset(start); 31 //每页查询多少条数据 32 query.setRows(pageSize); 33 //去solr查询并返回结果 34 ScoredPage<Item> page = solrTemplate.queryForPage(query, Item.class); 35 resultMap.put("rows",page.getContent()); 36 return resultMap; 37 } 38 }
3.控制层
1 @RestController 2 @RequestMapping("/itemsearch") 3 public class ItemSearchController { 4 @Reference 5 private ItemSearchService itemSearchService; 6 7 @RequestMapping("/search") 8 public Map<String, Object> search(@RequestBody Map searchMap ){ 9 return itemSearchService.search(searchMap); 10 } 11 }
