7月29号总结

一、在追加商品库存时，只显示还没有库存的商品

1、在stockList中点击  <a class="btn btn-success" href="initAddStock">

                             <i class="glyphicon glyphicon-zoom-in icon-white"></i> 追加</a>

2、在Controller对应的路径写下列代码：

@RequestMapping(value = "initAddStock", method = RequestMethod.GET)

    public String initAddStock(Model model) {

    log.info("追加库存单据初始化");

    List<Item> commodityList = itemListComponent.getSurCommodityList();

    model.addAttribute("commodityList", commodityList);

    StockForm stockForm = new StockForm();

    model.addAttribute("stockForm", stockForm);

    return "manager/stock/addStock";

    }

3、在ItemListComponent进行下列处理

public List<Item> getSurCommodityList() {

return queryDao.executeForObjectList("Common.selectSurCommodity", null);

}

4、对应的sql文为

<select id="selectSurCommodity" parameterClass="java.lang.String"

resultClass="cn.agriculture.web.form.Item">

SELECT commodity_name as label,

commodity_id as value

FROM commodity

<isNotNull property="value">

WHERE brand_id = #value#

</isNotNull>

WHERE not exists(

SELECT stock.commodity_id

FROM stock

WHERE stock.commodity_id = commodity.commodity_id)

</select>

5、在出错时在addStock中要获得正确的值

        List<Item> commodityList = itemListComponent.getSurCommodityList();

二、编辑商品信息并实现修改

1、在stockList中点击<a class="btn btn-info" href="initEditStock?stockId=${stockInfo.stockId}"> 

                                <iclass="glyphicon glyphicon-edit icon-white"></i> 编辑</a>

2、在Controller对应的路径写下列代码：

@RequestMapping(value = "initEditStock", method = RequestMethod.GET)

public String initEditStock(Model model, StockForm stockForm) {

log.info("修改库存单据信息初始化");

StockForm result = itemListComponent.getEditCommodity(stockForm);

    model.addAttribute("stockForm", result);

return "manager/stock/editStock";

}

3、在ItemListComponent进行下列处理

public StockForm getEditCommodity(StockForm frm) {

return queryDao.executeForObject("Stock.selectEditCommodity", frm,StockForm.class);

}

4、对应的sql文为

       <select id="selectEditCommodity"

        parameterClass="cn.agriculture.web.form.StockForm"

        resultClass="cn.agriculture.web.form.StockForm">

        select stock_id as stockId,

commodity.commodity_id as commodityId,

      commodity.commodity_name as commodityName,

      stock.stock as stock,

      stock.note as note

from stock,commodity

where stock.commodity_id = commodity.commodity_id

and stock.stock_id = #stockId#

</select>

5、在edit页面要hidden形式把Id和Name到stockForm，这样在出错的情况的才能获得Id和Name

         <input type="hidden" name="commodityId" value="${stockForm.commodityId}"/>

       <input type="hidden" name="commodityName" value="${stockForm.commodityName}"/>
