~~根据输入流获取文本内容

}

}

if (bufferedReader !=null) {

try {

bufferedReader.close();

~~获取输入文件流的内容

public StringBuilder getFieldContent(HttpServletRequest request,String key)throws Exception {

StringBuilder xmlContent =null;

CommonsMultipartResolver multipartResolver =new CommonsMultipartResolver(

request.getSession().getServletContext());

if (multipartResolver.isMultipart(request)) {

MultipartHttpServletRequest multiRequest = (MultipartHttpServletRequest) request;

String fileName =multipartFile.getOriginalFilename();

CommonsMultipartFile cf = (CommonsMultipartFile)multipartFile;

String form_name =cf.getFileItem().getFieldName();

if (form_name.equals(key)) {

xmlContent =impComSer.getStreamContent(multipartFile.getInputStream());

}

}

}

}

return xmlContent;

}

~~xml转json

System.out.println(xml);

InputStream is =new ByteArrayInputStream(xml.getBytes("UTF-8"));

XMLSerializer xmlSerializer =new XMLSerializer();

JSON json =xmlSerializer.readFromStream(is);

System.out.println(json);
