（1）qingcheng_interface工程新增接口 SkuSearchService 服务接口新增方法定义
public interface SkuSearchService {
public Map search(Map<String,String> searchMap);
}
（2）qingcheng_service_goods工程新增服务实现类SkuSearchServiceImpl 实现此方法，实现关键字查询
@Service
public class SkuSearchServiceImpl implements SkuSearchService {
@Autowired
private RestHighLevelClient restHighLevelClient;
public Map search(Map<String,String> searchMap) {
//1.封装查询请求
SearchRequest searchRequest=new SearchRequest("sku");
searchRequest.types("doc"); //设置查询的类型
SearchSourceBuilder searchSourceBuilder=new SearchSourceBuilder();
BoolQueryBuilder boolQueryBuilder = QueryBuilders.boolQuery();//布尔查询构建器
//1.1 关键字搜索
MatchQueryBuilder matchQueryBuilder= QueryBuilders.matchQuery("name",searchMap.get("keywords"));
boolQueryBuilder.must(matchQueryBuilder);
searchSourceBuilder.query(boolQueryBuilder);
searchRequest.source(searchSourceBuilder);
//2.封装查询结果
Map resultMap=new HashMap();
try {
SearchResponse searchResponse = restHighLevelClient.search(searchRequest, RequestOptions.DEFAULT);
SearchHits searchHits = searchResponse.getHits();
long totalHits = searchHits.getTotalHits();
System.out.println("记录数："+totalHits);
SearchHit[] hits = searchHits.getHits();
//2.1 商品列表
List<Map<String,Object>> resultList=new ArrayList<Map<String, Object>>();
for(SearchHit hit:hits){
Map<String, Object> skuMap = hit.getSourceAsMap();
resultList.add(skuMap);
}
resultMap.put("rows",resultList);
} catch (IOException e) {
e.printStackTrace();
}
return resultMap;
}
}
（3）qingcheng_web_portal工程新增类
@Controller
public class SearchController {
@Reference
private SkuSearchService skuSearchService;
@GetMapping("/search")
public String search(Model model, @RequestParam Map<String, String> searchMap) throws Exception {
//字符集处理
searchMap = WebUtil.convertCharsetToUTF8(searchMap);
//远程调用接口
Map result = skuSearchService.search(searchMap);
model.addAttribute("result", result);
return "search";
}
}
WebUtil类是工具类，用于字符集转码，资源中提供
1.3.3 模板构建
（1）qingcheng_web_portal工程新增模板，将资源\静态原型\网站前台\search.htm拷贝到WEB-INF下，并进行以下修改
<html xmlns:th="http://www.thymeleaf.org">
遍历查询结果
<ul class="yui3-g">
<li class="yui3-u-1-5" th:each="sku:${result.rows}">
<div class="list-wrap">
<div class="p-img">
<a href="item.html" target="_blank"><img th:src="${sku.image}" /></a>
</div>
<div class="price">
<strong>
<em>¥</em>
<i th:text="${#numbers.formatDecimal(sku.price/100.0,0,2)}"></i>
</strong>
</div>
<div class="attr">
<em th:text="${sku.name}"></em>
</div>
<div class="operate">
<a href="success-cart.html" target="_blank" class="sui-btn btn-bordered btn-danger">加入购物车</a>
<a href="javascript:void(0);" class="sui-btn btn-bordered">收藏</a>
</div>
</div>
</li>
</ul>
测试 浏览器输入 http://localhost:9102/search.do?keywords=手机
（2）修改index.html的关键字搜索表单
<form action="/search.do" class="sui-form form-inline">
<!--searchAutoComplete-->
<div class="input-append">
<input type="text" name="keywords" id="autocomplete" class="input-error input-xxlarge" />
<button class="sui-btn btn-xlarge btn-danger" >搜索</button>
</div>
</form>
修改search.html的关键字搜索表单，内容同上
