3、使用solrStringIntpageIntpublicpublicclassSearchResultprivateList<SearchItem>privateintpageCount;privateintcurPage;}使用TaotaoResult包装一个SearchResultDao参数：SolrQuery对象返回SearchResultpublicclassSearchDaoImplimplementsSearchDaoprivateSolrServerService3、调用dao5、返回3、publicpublicclassSearchServiceImplimplementsSearchServiceprivateSearchDaopublicSearchResultsearch(StringqueryString,intpage,introws)throwsExceptionSolrQueryquery=new=LongrecordCount=intpageCount=(int)(recordCount/if(recordCount%rows>{}returnsearchResult;}}参数keyword、page、publicclassSearchControllerprivatepublicclassSearchControllerprivateSearchService publicTaotaoResultsearch(@RequestParam(defaultValue="")Stringkeyword,@RequestParam(defaultValue="1")Integerpage,@RequestParam(defaultValue="30")Integerrows){trykeyword=newString(keyword.getBytes("iso8859-1"),"utf-8");SearchResultsearchResult=searchService.search(keyword,page,rows);returnTaotaoResult.ok(searchResult);}catch(Exceptione)}}}调用taotao-search发布的服务，实现搜索。使用Http 把json转换成java对象。把java对象传递给页面。ServicepublicclassSearchServiceImplimplementsSearchServicepublicclassSearchServiceImplimplementsSearchServiceprivateStringsearch(Stringkeyword,intpage,introws)Map<String,String>param=newHashMap<>();param.put("keyword",keyword);param.put("page",page+"");param.put("rows",rows+Stringjson= SearchResultsearchResult=(SearchResult)}}returnpublicclassSearchControllerprivateSearchService publicStringsearch(@RequestParam("q")Stringkeyword,@RequestParam(defaultValue="1")Integerpage,@RequestParam(defaultValue="60")Integerrows,Modelmodel){try}catch(UnsupportedEncodingException{keyword="";}SearchResultsearchResult=searchService.search(keyword,page,model.addAttribute("query",keyword);model.addAttribute("itemList",searchResult.getItemList());model.addAttribute("page",searchResult.getCurPage());return}}修改ItemSearch：Solr高可用。Zookeeper有和投票的机制。集群中至少应该有三个节点。个节点都到zookeeper上取配置文件。Zookeeper：3Solr：4第二步：把zookeeper解压。第三步：把zookeeper向/usr/local/solr-cloud 5、进入confzoo_sample.cfg文件改名为6、修改zoo.cfgdataDir=属性指定为刚创建的data 8、在zoo.cfg中添加如下内容：第四步：启动zookeeperZookeeper的 下有一个bin 启动：./zkServer.shstart第三步：为每个solr实例创建一solrhome。第五步：修改每个solrhomesolr.xml文件。修改host、hostPort两个属性。分别是对应的ip及端。./zkcli.sh-zkhost54:2181,54:2182,54:2183-cmd./zkcli.sh-zkhost54:2181,54:2182,54:2183-cmd使用zookeeperzkCli.sh命令。第八步：告诉solr实例zookeepertomcatcatalina.sh使用solrJpu
