java配置solr接口

<bean id="solrServer" class="org.apache.solr.client.solrj.impl.HttpSolrServer">
	<constructor-arg value="http://192.168.200.128:8080/solr" />

前台搜索

controller层：

@Autowired
private SearchService searchService;
@Autowired
private BrandService brandService;

@RequestMapping(value="/search")
public String search(Integer pageNo,String keyword,Long brandId,String price,Model model){
	
	List<Brand> brands = brandService.selectBrandListFromRedis();
	//信息的回显
	model.addAttribute("brands", brands);
	model.addAttribute("brandId", brandId);
	model.addAttribute("price", price);
	
	//已选容器Map（已选标签回显）
	Map<String,String> map = new HashMap<String,String>();
	if(null!=brandId){
		for (Brand brand : brands) {
			if(brandId == brand.getId()){
				map.put("品牌", brand.getName());
				break;
			}
		}
	}		
	if(null != price&& "" !=price){
		if(price.contains("-")){
			map.put("价格", price);
		}else{
			map.put("价格", price+"以上");
		}
	}
	model.addAttribute("map", map);
	Pagination pagination = searchService.selectPaginationListByQuery(pageNo, keyword,brandId,price);
	model.addAttribute("pagination",pagination);
	return "search";
