九乡新闻网高层住宅地下室用途:Tapestry4集成Oracle InterMedia
来源：百度文库 编辑：九乡新闻网 时间：2024/04/29 17:07:55
第一步：在web.xml配置interMedia的filter
第二步：定义自己的MultipartDecoderFilter
仿照tapestry的MultipartDecoderFilter，写自己的MultipartDecoderFilter（例如类名为org.MYMultipartDecoderFilter)，自己写的filter和tapestry相比主要是判断request是否已被包装，如果被包装了就直接继续处理（见下列代码的if-else部分）
public void service(HttpServletRequest request, HttpServletResponse response, ServletRequestServicer servicer)
throws IOException, ServletException ...{
String contentType = request.getContentType(); // contentType is occasionally null in testing. The browser tacks on additional // information onto the contentType to indicate where the boundaries are in // the stream. boolean encoded = contentType != null && contentType.startsWith("multipart/form-data");
try ...{ //HttpServletRequest newRequest = encoded ? _decoder.decode(request) : request; HttpServletRequest newRequest = null;if (request instanceof HttpServletRequestWrapper) ...{
newRequest = request; } else ...{ newRequest = encoded ? _decoder.decode(request) : request;
} servicer.service(newRequest, response); } finally ...{ if (encoded) _decoder.cleanup(); // System.out.println("ttt"); }
}
在hivemodul中配置使用：
Identifies upload requests and passes them to the MultipartDecoder service for decoding. 第三步：开始处理
页面中注入属性：
html中使用表单的文件上传元素（input type="file" name="upload"/>）或upload组件
在页面类中即可得到interMedia类型的上传文件：
RequestGlobals obj = this.getRequestGlobals();OrdMultipartWrapper obj1 = (OrdMultipartWrapper) obj.getRequest();
OrdHttpUploadFile[] files = obj1 .getFileParameterValues("upload");
