以下查询，controller调用的均是service的search方法！！
普通查询(关键代码)
import org.springframework.beans.factory.annotation.Autowired; import org.springframework.data.solr.core.SolrTemplate; import org.springframework.data.solr.core.query.Criteria; import org.springframework.data.solr.core.query.Query; import org.springframework.data.solr.core.query.SimpleQuery; import org.springframework.data.solr.core.query.result.ScoredPage; import com.alibaba.dubbo.config.annotation.Service; import com.pinyougou.pojo.TbItem; import com.pinyougou.search.service.ItemSearchService; @Service(timeout=5000) public class ItemSearchServiceImpl implements ItemSearchService { @Autowired private SolrTemplate solrTemplate; @Override public Map search(Map searchMap) { Map map=new HashMap(); Query query=new SimpleQuery("*:*"); Criteria criteria=new Criteria("item_keywords").is(searchMap.get("keywords")); query.addCriteria(criteria); ScoredPage<TbItem> page = solrTemplate.queryForPage(query, TbItem.class); map.put("rows", page.getContent()); return map; } }
高亮查询（关键代码）
@Service(timeout=5000) public class ItemSearchServiceImpl implements ItemSearchService { @Autowired private SolrTemplate solrTemplate; /** * 根据关键字搜索列表 * @param searchMap * @return */ private Map searchList(Map searchMap){ Map map=new HashMap(); HighlightQuery query=new SimpleHighlightQuery(); HighlightOptions highlightOptions=new HighlightOptions().addField("item_title");//设置高亮的域 highlightOptions.setSimplePrefix("<em style='color:red'>");//高亮前缀 highlightOptions.setSimplePostfix("</em>");//高亮后缀 query.setHighlightOptions(highlightOptions);//设置高亮选项 //按照关键字查询 Criteria criteria=new Criteria("item_keywords").is(searchMap.get("keywords")); query.addCriteria(criteria); HighlightPage<TbItem> page = solrTemplate.queryForHighlightPage(query, TbItem.class); for(HighlightEntry<TbItem> h: page.getHighlighted()){//循环高亮入口集合 TbItem item = h.getEntity();//获取原实体类 if(h.getHighlights().size()>0 && h.getHighlights().get(0).getSnipplets().size()>0){ item.setTitle(h.getHighlights().get(0).getSnipplets().get(0));//设置高亮的结果 } } map.put("rows",page.getContent()); return map; } @Override public Map search(Map searchMap) { Map map=new HashMap(); //1.查询列表 map.putAll(searchList(searchMap)); return map; } }
分组查询（关键代码）
import java.util.ArrayList; import java.util.HashMap; import java.util.List; import java.util.Map; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.data.domain.Page; import org.springframework.data.solr.core.SolrTemplate; import org.springframework.data.solr.core.query.*; import org.springframework.data.solr.core.query.result.*; import com.alibaba.dubbo.config.annotation.Service; import com.pinyougou.pojo.TbItem; import com.pinyougou.search.service.ItemSearchService; @Service(timeout = 5000) public class ItemSearchServiceImpl implements ItemSearchService { @Autowired private SolrTemplate solrTemplate; @Override public Map search(Map searchMap) { Map map = new HashMap(); //1.查询列表 map.putAll(searchList(searchMap)); List categoryList = searchCategoryList(searchMap); map.put("categoryList",categoryList); return map; } /** * 查询分类列表 * * @param searchMap * @return */ private List searchCategoryList(Map searchMap) { List<String> list = new ArrayList(); Query query = new SimpleQuery(); //按照关键字查询 Criteria criteria = new Criteria("item_keywords").is(searchMap.get("keywords")); query.addCriteria(criteria); //设置分组选项 GroupOptions groupOptions = new GroupOptions().addGroupByField("item_category"); query.setGroupOptions(groupOptions); //得到分组页 GroupPage<TbItem> page = solrTemplate.queryForGroupPage(query, TbItem.class); //根据列得到分组结果集 GroupResult<TbItem> groupResult = page.getGroupResult("item_category"); //得到分组结果入口页 Page<GroupEntry<TbItem>> groupEntries = groupResult.getGroupEntries(); //得到分组入口集合 List<GroupEntry<TbItem>> content = groupEntries.getContent(); for (GroupEntry<TbItem> entry : content) { list.add(entry.getGroupValue());//将分组结果的名称封装到返回值中 } return list; } /** * 根据关键字搜索列表 * * @param searchMap * @return */ private Map searchList(Map searchMap) { Map map = new HashMap(); HighlightQuery query = new SimpleHighlightQuery(); HighlightOptions highlightOptions = new HighlightOptions().addField("item_title");//设置高亮的域 highlightOptions.setSimplePrefix("<em style='color:red'>");//高亮前缀 highlightOptions.setSimplePostfix("</em>");//高亮后缀 query.setHighlightOptions(highlightOptions);//设置高亮选项 //按照关键字查询 Criteria criteria = new Criteria("item_keywords").is(searchMap.get("keywords")); query.addCriteria(criteria); HighlightPage<TbItem> page = solrTemplate.queryForHighlightPage(query, TbItem.class); for (HighlightEntry<TbItem> h : page.getHighlighted()) {//循环高亮入口集合 TbItem item = h.getEntity();//获取原实体类 if (h.getHighlights().size() > 0 && h.getHighlights().get(0).getSnipplets().size() > 0) { item.setTitle(h.getHighlights().get(0).getSnipplets().get(0));//设置高亮的结果 } } map.put("rows", page.getContent()); return map; } }
