spring对commons_fileupload和cos_fileuplaod的封装

类图如下所示：

 

实例：

java 代码

// 获得context
javax.servlet.ServletContext servletContext = getServletContext();

// 获得resolver
MultipartResolver cmr =   new  CommonsMultipartResolver(servletContext);

// 获得request
MultipartHttpServletRequest multipartRequest  =  cmr.resolveMultipart(request);

// 转型为Default
DefaultMultipartHttpServletRequest defaultRequest = (DefaultMultipartHttpServletRequest)multipartRequest;

// 获得普通表单域的值
String txt = (String)defaultRequest.getParameter( " txt1 " );

// 获得文件表单域
MultipartFile file  =  multipartRequest.getFile( " file1 " );

// 获得这个文件的相关属性
String filename  =  file.getOriginalFilename();
long  filesize = file.getSize();
String contentType = file.getContentType();

// 产生文件名和空文件
File toFile = new  File( " c:\\test.jpg " );

// 上传
file.transferTo(toFile);
