添加商品时选择类别时的下拉列表（适合新手。请高手改正）

一、

在类的form.jsp 添加快捷方便不须修改controller类

<%@ page import="java.io.*,java.util.*,java.sql.*"%><%@ page import="javax.servlet.http.*,javax.servlet.*" %><%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%><%@ taglib uri="http://java.sun.com/jsp/jstl/sql" prefix="sql"%><html><head><title>JSTL sql:query Tag</title></head><body> <sql:setDataSource var="snapshot" driver="com.mysql.jdbc.Driver"     url="jdbc:mysql://localhost/TEST"     user="root"  password="pass123"/><sql:query dataSource="${snapshot}" var="result">SELECT * from Employees;</sql:query> <div class="control-group"><label class="control-label">所属分类 category_no：</label><div class="controls"><form:select path="categoryno"   class="input-xlarge">

<form:option value="" label="请选择"/>

<c:forEach var="row" items="${result.rows}" >

修改时获得所选类别名称

<option value="${row.categoryno}"  ${row.categoryno eq llShopGoods.categoryno ?'selected':''}>${row.categoryname}</option>

</c:forEach>

</form:select>

</div></div>

二、

修改controller 类

/** * 编辑Controller * @author 王俊山 * @version 2016-05-14 */@Controller@RequestMapping(value = "${adminPath}/shopgoods/llShopGoods")public class LlShopGoodsController extends BaseController {@Autowiredprivate LlShopGoodsService llShopGoodsService;

添加下拉列表关联service@Autowiredprivate LlShopGoodsCategoryService llShopGoodsCategoryService;修改form方法@RequiresPermissions("shopgoods:llShopGoods:view")@RequestMapping(value = "form")public String form(LlShopGoods llShopGoods,LlShopGoodsCategory llShopGoodsCategory, Model model) {List<LlShopGoodsCategory> list =llShopGoodsCategoryService.findList(llShopGoodsCategory);model.addAttribute("llShopGoods", llShopGoods);model.addAttribute("list",list);return "modules/shopgoods/llShopGoodsForm";}

form.jsp

<div class="control-group"><label class="control-label">所属分类 category_no：</label><div class="controls"><form:select path="categoryno"   class="input-xlarge"> <form:option value="" label="请选择"/> <c:forEach var="row" items="${list}" ><option value="${row.categoryno}"  ${row.categoryno eq llShopGoods.categoryno ?'selected':''}>${row.categoryname}</option></c:forEach></form:select></div></div>
