SWFUpload官方的例子都是PHP的，在这里提供一个Java版的最简单的使用例子，使用JSP页面完成所有操作。

效果图如下

实现上传，分为三步：

1、JavaScript设置SWFUpload部分（与官方例子类似）：

<span style="font-family:KaiTi_GB2312;font-size:14px;">var upload;  
      
     window.onload = function() {  
    upload = new SWFUpload({  
      
    // 处理文件上传的url  
    upload_url: "${pageContext.request.contextPath}/swfupload/example.jsp?upload=1",      
    // 上传文件限制设置  
    file_size_limit : "10240",  // 10MB  
    file_types : "*.jpg;*.gif;*.png",   //此处也可以修改成你想限制的类型，比如：*.doc;*.wpd;*.pdf  
    file_types_description : "Image Files",  
    file_upload_limit : "0",  
    file_queue_limit : "1",  
    // 事件处理设置（所有的自定义处理方法都在handler.js文件里）  
    file_dialog_start_handler : fileDialogStart,  
    file_queued_handler : fileQueued,  
    file_queue_error_handler : fileQueueError,  
    file_dialog_complete_handler : fileDialogComplete,  
    upload_start_handler : uploadStart,  
    upload_progress_handler : uploadProgress,  
    upload_error_handler : uploadError,  
    upload_success_handler : uploadSuccess,  
    upload_complete_handler : uploadComplete,  
    // 按钮设置  
    button_image_url : "swfupload/xpbutton.png",    // 按钮图标  
    button_placeholder_id : "spanButtonPlaceholder",  
    button_width: 61,  
    button_height: 22,  
    // swf设置  
    flash_url : "swfupload/swfupload.swf",  
    custom_settings : {  
        progressTarget : "fsUploadProgress",  
        cancelButtonId : "btnCancel"  
    },  
        // Debug 设置  
        debug: false  
    });  
     }  </span>

2、页面显示部分：

3、Java处理文件上传部分：

<span style="font-family:KaiTi_GB2312;font-size:14px;">String uploadSign = request.getParameter("upload");  
     String rootPath = request.getParameter("rootPath");  
     String path = request.getParameter("path");  
     if(rootPath == null) rootPath = "";  
        rootPath = rootPath.trim();  
     if(rootPath.equals("")){  
    rootPath = application.getRealPath("/swfupload/files");  
     }  
     if(path == null) {  
    path = rootPath;  
     }else{  
    path = new String(Base64.decodeBase64(path.getBytes()));  
     }  
      
     //上传操作  
     if(null != uploadSign && !"".equals(uploadSign)){  
      FileItemFactory factory = new DiskFileItemFactory();  
      ServletFileUpload upload = new ServletFileUpload(factory);  
      //upload.setHeaderEncoding("UTF-8");  
      try{  
          List items = upload.parseRequest(request);  
          if(null != items){  
              Iterator itr = items.iterator();  
              while(itr.hasNext()){  
                  FileItem item = (FileItem)itr.next();  
                  if(item.isFormField()){  
                      continue;  
                  }else{  
                                            //以当前精确到秒的日期为上传的文件的文件名  
                      SimpleDateFormat sdf=new SimpleDateFormat("yyyyMMddkkmmss");  
                      String type = item.getName().split("\\.")[1];//获取文件类型  
                      File savedFile = new File(path,sdf.format(new Date())+"."+type);  
                      item.write(savedFile);  
                  }  
              }  
          }  
      }catch(Exception e){  
          e.printStackTrace();  
      }  
     }  </span>
