SpringMVC表單對象綁定到@ModelAttribute

支持綁定表單對象

jsp：

<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form" %>
<form:form id="itemForm" action="${pageContext.request.contextPath }/items/editItemSubmit.action" method="post" modelAttribute="items">
    <form:input path="id" type="hidden"/>
    修改商品信息：
    <table width="100%" border=1>
        <tr>
            <td>商品名稱</td>
            <td><form:input path="name" /></td>
        </tr>
        <tr>
            <td colspan="2" align="center">
                <input type="submit" value="提交"/>
            </td>
        </tr>
    </table>
</form:form>

controller：

@RequestMapping("/editItemSubmit")
    public String editItemSubmit(@ModelAttribute Items items,Model model){
        itemsService.updateItems(items);
        System.out.println(items);
        return "forward:list.action";
    }

 

重點是<form:input/>中的modelAttribute
