shop--10.店鋪詳情（後臺+前端相似於shoplist）
1.獲取店鋪的詳細信息和商品類別列表javascript
/**
* 獲取店鋪信息和該店鋪下的商品類別列表
* @param request
* @return
*/
@RequestMapping(value = "/getshopdetailpageinfo", method= RequestMethod.GET)
@ResponseBody
private Map<String, Object> getShopDetailPageInfo(HttpServletRequest request){
Map<String, Object> modelMap = new HashMap<>();
Long shopId = HttpServletRequestUtil.getLong( request, "shopId" );
Shop shop = null;
List<ProductCategory> productCategoryList = null;
//獲取店鋪id爲shopId的商品信息
if(shopId != -1){
//獲取shopId的店鋪信息
shop = shopService.getShopByShopId( shopId );
//獲取該店鋪下的商品列表
productCategoryList = productCategoryService.getProductCategoryList( shopId );
modelMap.put( "success", true );
modelMap.put( "shop", shop );
modelMap.put( "productCategoryList", productCategoryList );
} else{
modelMap.put( "success", false );
modelMap.put( "errMsg", "empty shopId" );
}
return modelMap;
}
2.根據查詢條件，返回該店鋪下的商品詳細信息css
/**
* 根據查詢條件，分頁列出該店鋪下的商品信息
* @param request
* @return
*/
@RequestMapping(value = "/prouctlistbyshop", method = RequestMethod.GET)
@ResponseBody
private Map<String, Object> productListByShop(HttpServletRequest request){
Map<String, Object> modelMap = new HashMap<>( );
//獲取頁碼
int pageIndex = HttpServletRequestUtil.getInt( request, "pageIndex" );
//獲取每頁的信息數量
int pageSize = HttpServletRequestUtil.getInt( request, "pageSize" );
//獲取shopId
Long shopId = HttpServletRequestUtil.getLong( request, "shopId");
//空值判斷
if(pageIndex > -1 && pageSize > -1 && shopId > -1){
//獲取productCategoryId
Long productCategoryId = HttpServletRequestUtil.getLong( request, "productCategoryId" );
//獲取productName 進行模糊查詢
String productName = HttpServletRequestUtil.getString( request, "productName" );
Product productCondition = compactProuctCondition4Search(shopId, productCategoryId, productName);
ProductExecution productExecution = productService.getProductList( productCondition, pageIndex, pageSize);
modelMap.put( "success", true );
modelMap.put( "productList", productExecution.getProductList() );
modelMap.put( "count", productExecution.getCount() );
} else{
modelMap.put( "success", false );
modelMap.put( "errMsg", "empty pageSize or pageIndex or shopId" );
}
return modelMap;
}
/**
* 組合查詢條件到productCondition，進行進一步的店鋪下的相關商品信息查詢
* @param shopId
* @param productCategoryId
* @param productName
* @return
*/
private Product compactProuctCondition4Search(Long shopId, Long productCategoryId, String productName) {
Product productCondition = new Product();
Shop shop = new Shop();
shop.setShopId( shopId );
productCondition.setShop( shop );
//查詢某個商品類別下的商品列表
if(productCategoryId != -1){
ProductCategory productCategory = new ProductCategory();
productCategory.setProductCategoryId( productCategoryId );
productCondition.setProductCategory( productCategory );
}
//進行productName的模糊查詢
if(productName != null){
productCondition.setProductName(productName);
}
//只查詢商品中status=1的上架的商品
productCondition.setStatus( 1 );
return productCondition;
}
