springMVC上传多个文件

Controller类中：

//@RequestParam:数组的注解，

@RequestMapping(value="add",method=RequestMethod.POST)

public String add(@Validated User users,BindingResult br,

@RequestParam(value="attachs") MultipartFile attachs[],

HttpServletRequest request) throws IOException{

//你需要验证的对象后边要紧跟BindingResult

if(br.hasErrors()){//有错误，不提交。相当于异常回滚

return "user/addUser";

}

for(MultipartFile attach:attachs){

if(!attach.isEmpty()){

//上传单个文件，添加附件

//上传的路径：

String realName=request.getSession().

getServletContext().getRealPath("/statics/upload");

//File.separator:自动辨别电脑系统：用该为"/"还是"\"

File file=new File(realName+File.separator+attach.

getOriginalFilename());

//上传：

FileUtils.copyInputStreamToFile(attach.getInputStream(),

file);

System.out.println("===============>");

System.out.println(attach.getName());

System.out.println(attach.getOriginalFilename());

System.out.println(attach.getContentType());

}

}

映射文件中添加以下内容：

<!-- 文件上传 ：-->

<!-- id的值必须为：multipartResolver -->

<bean id="multipartResolver"

class="org.springframework.web.multipart.commons.CommonsMultipartResolver">

<!-- one of the properties available; the maximum file size in bytes -->

<property name="maxUploadSize" value="500000"/>

</bean>

jsp页面添加相应的添加按钮即可
