Spring CommonsMultipartResolver文件上传的使用

Java代码

...Controller...{

//创建一个通用的多部分解析器.
CommonsMultipartResolver commonsMultipartResolver = new
CommonsMultipartResolver(request.getSession().getServletContext());
//设置编码
commonsMultipartResolver.setDefaultEncoding(”utf-8″);
//判断 request 是否有文件上传,即多部分请求...
if (commonsMultipartResolver.isMultipart(request))
{
//转换成多部分request
MultipartHttpServletRequest multipartRequest =
commonsMultipartResolver.resolveMultipart(request);

// file 是指 文件上传标签的 name=值
// 根据 name 获取上传的文件...
MultipartFile file = multipartRequest.getFile("file");

//上传后记录的文件...
File imageFile = new File("fileName");
//上传...
file.transferTo(imageFile);

}
}

action="/msgupload" target="upload_if">
