这是异常，下面开始上代码，一个简单的更新操作.
Tbitem和继承类ItemCustom:
public class ItemCustom extends TbItem{
}
public class TbItem {
private Long id;
private String title;
private String sellPoint;
private Long price;
private Integer num;
private String barcode;
private String image;
private Long cid;
private Byte status;
private Date created;
private Date updated;
//省略get/set方法
UpdateMapper.xml
<mapper namespace="com.taotao.mapper.UpdateMapper">
<update id="updateItemsById" parameterType="com.taotao.wto.ItemCustom">
UPDATE tb_item SET title = '#{title}',price = #{price},num = #{num} WHERE id = #{id}
</update>
</mapper>
mapper接口：
public interface UpdateMapper {
ItemCustom updateItemsById(Long id,ItemCustom itemCustom);
}
service层的代码：
@Override
public void updateItems(Long id, ItemCustom itemCustom) {
updateMapper.updateItemsById(id, itemCustom);
}
controller:
//更新商品，提交商品更新信息
@RequestMapping("/editItemsSubmit")
public String editItemsSubmit(Long id,ItemCustom itemCustom){
itemService.updateItems(id, itemCustom);
return "success";
}
最后是editItems.jsp:
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/fmt" prefix="fmt"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>修改商品信息</title>
</head>
<body>
<!-- submit后，表单提交到此action路径 -->
<form id="itemForm" action="${pageContext.request.contextPath }/editItemsSubmit.action" method="post" enctype="multipart/form-data">
<input type="hidden" name="id" value="${itemCustom.id }"/>
修改商品信息：
<table width="100%" border=1>
<tr>
<td>商品名称</td>
<td><input type="text" name="title" value="${itemCustom.title }"/></td>
</tr>
<tr>
<td>商品价格</td>
<td><input type="text" name="price" value="${itemCustom.price }"/></td>
</tr>
<tr>
<td>商品数量</td>
<td><input type="text" name="num" value="${itemCustom.num}"/></td>
</tr>
<tr>
<td colspan="2" align="center"><input type="submit" value="提交"/>
</td>
</tr>
</table>
</form>
</body>
</html>
求帮忙看看问题在哪，谢谢。
