用Buffalo实现文件上传，request没有发现multipart/form-data

[acale...@gmail.com]

使用APACHE的coomons-fileupload-1.2.1.jar及commons-io-1.4.jar实现文件上传，以下代码在
Servlet.doPost()中，工作正常，即实现了文件上传：
---------------------------------------------------------------------------------------------------------------------------
//上传组件
MutiFileUpload upload = new MutiFileUpload();
upload.parseRequest(request);
File parent = new File("C:\\upload\\");
try {
upload.upload(parent);
} catch
(org.apache.commons.fileupload.FileUploadBase.SizeLimitExceededException
e) {
// 文件大小超出最大值
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
---------------------------------------------------------------------------------------------------------------------------
把这段代码放在一个buffalo Service中的一个方法实现（此Service工作正常）baseService：
---------------------------------------------------------------------------------------------------------------------------
HttpServletRequest request =
RequestContext.getContext().getHttpRequest();
...
public int mutiFileUpload() throws UnsupportedEncodingException {
return baseDao.mutiFileUpload(request);
}
----------------------------------------------------------------------------------------------------------------------------
baseDao实现上传：
----------------------------------------------------------------------------------------------------------------------------
MutiFileUpload upload = new MutiFileUpload();
upload.parseRequest(request);
File parent = new File("C:\\upload\\");
try {
upload.upload(parent);
} catch
(org.apache.commons.fileupload.FileUploadBase.SizeLimitExceededException
e) {
// 文件大小超出最大值
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
return 1;
----------------------------------------------------------------------------------------------------------------------------
系统抛出错误：
----------------------------------------------------------------------------------------------------------------------------

buffalo协议本身不支持文件上传。一般来说，采用传统方式来进行文件上传，采用buffalo来显示文件上传进度。

将来是否会有新版本计划？或者说，在新版本中增加此功能。

文件上传的需求千奇百怪。我目前所经历的Web项目中，几乎每个都有自己的特定需求。除了HTTP上传本身没什么变化，表现形式上，行为交互上各有不同。如果不能抽象出一致的行为，框架能做出的抽象也有限。

上传文件用JAVA来实现，绘制进度条用buffalo取session中的参数对象的值，但这样一来，是用BUFFALO CALL 后台取得用
JAVA写入前台的对象，我感觉还不如用JAVA直接写COOKIE到前台，用JS直接取COOKIE中的参数来实现绘制进度条的任务，相比之下，哪种
方法性能更好一些呢？。

性能不会有太大的差异。

COOKIE受浏览器的影响大一些，最后，我还是选择了BUFFALO结合COMMONS-FILEUPLOAD组件来完成状态条的绘制工作。看上去效
果还可以。

Buffalo 是否有计划配合Spring的 Annotation的Feature，做一次小版本的提升，实现自动注入啊？

具体看起来是什么样子呢？

以前有人写过，只需要在Service上写一个@BuffaloServer("serviceName")就可以让系统自动识别buffaloService.

BUFFALO与SPRING集成，是否只支持：
org.springframework.web.context.ContextLoaderServlet？
目前用LISTENER配置的较多，优势也较大。我想，如果新版本（小版本）的BUFFALO增加这两项支持就好了，也比较有生命力，毕竟
ANNOTATION是J2EE 5 的重要特性：
1 支持LISTENER配置。
2 实现自去注入功能。

Listener也可以支持。例子里面只是一种演示而已。只要保证在上下文环境中Spring被正确的加载，buffalo就能找到对应的service.
