文件上传
1. 配置上传页面
<form action="${pageContext.request.contextPath}/file.action" enctype="multipart/form-data">
<table align="center" border="1" width="45%">
<tr>
<td colspan="2" align="center">文件上传</td>
</tr>
<tr>
<td>商品图片:</td>
<td><input name="photo" type="file"/></td>
</tr>
<tr>
<td colspan="2" align="center"><input type="submit" value="http://www.mamicode.com/提交"/></td>
</tr>
</table>
2. 解析上传文件
@Controller
public class FileController {
//转向文件长传页面
@RequestMapping("/toFile.action")
public String toFile(){
return "file";
}
@RequestMapping("/file.action")
public String updloadFile(MultipartFile photo,Model model) throws IOException{
//简单方式
FileUtils.writeByteArrayToFile
(new File("D:\\图片样例\\"+photo.getOriginalFilename()), photo.getBytes());
model.addAttribute("msg", "文件上传成功");
//return "forward:/toFile.action";
return "redirect:/toFile.action";
}
}
3. 配置文件上传解析器
<!--配置文件上传解析器 id的名称必须为:multipartResolver-->
<bean id="multipartResolver"
class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<property name="maxUploadSize" value="http://www.mamicode.com/10485760"></property>
</bean>
