在EditStock页面中

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

<input type="hidden" name="commodityName" value="${stockForm.commodityName}"/>//显示前要先将值传过来

${stockForm.commodityName}    //直接显示商品名称

在StockController里

@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 re = stockService.searchEditStock(stockForm);

model.addAttribute("stockForm", re);   将查询的值传回stockForm里

       return "manager/stock/editStock";

}

在stockService里

public StockForm searchEditStock(StockForm re) {

     return queryDao.executeForObject("Stock.selectEditStock", re, StockForm.class);

}

对应的SQL文

<select id="selectEditStock" 

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

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

SELECT  stock.stock_id as stockId,

       commodity.commodity_name as commodityName,

commodity.commodity_id as commodityId,

stock.stock as stock,

 stock.note as note

FROM stock,commodity

WHERE stock.commodity_id=commodity.commodity_id

AND stock.stock_id=#stockId#

</select>
