1.获取店铺的详细信息和商品类别列表
/**

* @param request
* @return
*/
@RequestMapping(value = "/getshopdetailpageinfo", method= RequestMethod.GET)
@ResponseBody
private Map<String, Object> getShopDetailPageInfo(HttpServletRequest request){

//获取店铺id为shopId的商品信息
if(shopId != -1){
//获取shopId的店铺信息

//获取该店铺下的商品列表
productCategoryList = productCategoryService.getProductCategoryList( shopId );
modelMap.put( "success", true );

modelMap.put( "productCategoryList", productCategoryList );
} else{
modelMap.put( "success", false );
modelMap.put( "errMsg", "empty shopId" );
}
return modelMap;
}
2.根据查询条件，返回该店铺下的商品详细信息
/**

* @param request
* @return
*/

//获取productCategoryId
Long productCategoryId = HttpServletRequestUtil.getLong( request, "productCategoryId" );
//获取productName 进行模糊查询
String productName = HttpServletRequestUtil.getString( request, "productName" );
Product productCondition = compactProuctCondition4Search(shopId, productCategoryId, productName);

}
return modelMap;
}
/**

//查询某个商品类别下的商品列表
if(productCategoryId != -1){

}
//进行productName的模糊查询
if(productName != null){
productCondition.setProductName(productName);
}
//只查询商品中status=1的上架的商品
