OFBIZ的上传文件方法

 

普通方式：

org.apache.commons.fileupload.disk.DiskFileItemFactory的jar包自己写的方法。

那个方法里核心是调用了

DiskFileItemFactory factory = new DiskFileItemFactory();

ServletFileUpload upload = new ServletFileUpload(factory);

List fileItems =   fileItems = upload.parseRequest(request);

 

示例代码：

public static String processFormData(HttpServletRequest request, Map formMap) {

        String message = "";

        DiskFileItemFactory factory = new DiskFileItemFactory();

        ServletFileUpload upload = new ServletFileUpload(factory);

        String value = PropertiesUtil.getConfigureMessage("image-upload-max-size");

        int imageMaxSize = Integer.parseInt(value);

        int formMaxSize = 30 * 1024 * 1024;

        upload.setSizeMax(formMaxSize);

        List fileItems = null;

        try {

            fileItems = upload.parseRequest(request);

        } catch (FileUploadException ex) {

            message = PropertiesUtil.getErrorMessage("utilhttp.upload.oversize");

            return message;

        }

        Iterator it = fileItems.iterator();

        FileItem fileItem = null;

        String fieldName = null, fileName = null;

        long imgSize = 0;

        it = fileItems.iterator();

        while (it.hasNext()) {

            fileItem = (FileItem) it.next();

            fieldName = fileItem.getFieldName();

            if (fileItem.isFormField()) {

                formMap.put(fieldName, fileItem.getString().trim());

            } else {

                fileName = fileItem.getName();

                // no-select file

                if (fileName.trim() == "") {

                    continue;

                }

                imgSize = fileItem.getSize();

                if (imgSize > 0) {

                    if (fileName.lastIndexOf(File.separator) > 0) {

                        fileName = fileName.substring(fileName.lastIndexOf(File.separator) + 1);

                    }

                    fileName = fileName.toLowerCase();

                    if (!validateFileFormats(fileName)) {

                        message = PropertiesUtil.getErrorMessage("utilhttp.upload.photo.type.unallowed");

                        return message;

                    } else if (imgSize > imageMaxSize) {

                        message = "toolarge";

                        return message;

                    }

                    formMap.put(fieldName, fileItem.get());

                } else {

                    // empty image

                    message = "empty.image";

                    return message;

                }

            }

        }

        return null;

    }

 

 

 

 

 

 

还有另一种方法，ofbiz里有一个HttpRequestFileUpload的工具类。它的上传文件到服务器的方法是

HttpRequestFileUpload uploadObject = new HttpRequestFileUpload();

    uploadObject.setOverrideFilename(defaultFileName);

    uploadObject.setSavePath(imageServerPath + "/" + filePathPrefix);

    uploadObject.doUpload(request);

这两个类支出多线程和断点续传吗？不太了解，谢谢~~~
