省份与前页面的省份不重复

1.addExpressPrice.jsp

<div class="controls">

<form:select path="provinceId">

<form:options items="${provinceList}" itemLabel="label" itemValue="value" />

</form:select>

</div>

2.ExpressPriceController.java

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

 public String initAddExpressPrice(Model model, ExpressPriceForm expressPriceForm) {

  log.info("追加快递商所属价格初始化");

  List<Item> provinceList = itemListComponent.getProvinceList1();

  model.addAttribute("provinceList", provinceList);}

3.ItemListComponent.java

public List<Item> getProvinceList1() {

return queryDao.executeForObjectList("Common.selectProvince1", null);

}

4.CommonSqlMap.xml

<select id="selectProvince1"

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

SELECT province_name as label,

province_id as value

FROM   province

WHERE not exists(

SELECT express_price.province_id 

FROM express_price

WHERE express_price.province_id =province.province_id )

</select>

点"编辑"单条显示不能修改

在editExpressPrice.jsp把下拉列表形式修改成不可编辑

改前：

<td>  <div class="controls">

<form:select path="provinceId">

<form:options items="${provinceList}" itemLabel="label" itemValue="value" />

</form:select>

</div></td>

改后：

<td>

<div class="controls">

${expressPriceForm.provinceName} ////‍只快递的省份名称，不可修改

</div>

</td>

在ExpressPriceSqlMap.xml修改，

<select id="selectExpressPrice"

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

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

SELECT express_price.express_price_id as expressPriceId,

express_price.express_id as expressId,

province.province_name as provinceName,

express_price.province_id as provinceId,

express_price.separate_weight as separateWeight,

express_price.first_heavy_price as firstHeavyPrice,

express_price.continued_heavy_price as continuedHeavyPrice,

express_price.status as status,

express_price.note as note,

express_price.update_time as updateTime,

express_price.update_user as updateUser

FROM express_price,province

WHERE express_price.express_price_id = #expressPriceId#

    AND express_price.province_id =province.province_id

</select>

注明：经过express_price快递商价格表的全部字段名和province省份表的province_name来显示，从express_price,province表中调用的条件是express_price表的express_price_id = #expressPriceId#字段，和 express_price表的province_id =province.province_id字段。
