1，springMvc 上传单个文件
前端:简单的form表单
<form action="跳转地址" method="post" enctype="multipart/form-data">
<input type="file' name="photo" /><input type="submit" value="上传" />
</form>
后台控制层:
@RequestMapping("upload")
public String upload(@RequestParam("photo" multipartFile,HttpSession))throws Exception
{
if(!photo.isEmpty())
{
String path=session.getServletContext().getRealPath("储存地址");
String fileName = photo.getOriginalFilename();
if(fileName .endWith(".jpg") || fileName.endWith(".png"))
{
File file=new File(path,fileName);
photo.transferTo(file);
}else
{
return "上传失败";
}
}
return “上传成功”;
}
最后要想能够正常的上传还需要在spring-mybatis文件中配置
<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> //maxUploadSize指的是文件最大值 以B为单位 <property name="maxUploadSize"><value>100000000</value> </property> <property name="defaultEncoding"><value>UTF-8</value></property> </bean>
2，多个文件上传
前端:简单的form表单多个File
后台:用数组MultipartFile 然后for循环
