springmvc+dwz+xheditor實現上傳圖片及swf 視頻

注意：如果使用了apache fileupload上傳方法，則springmvc-servlet.xml的配置文件裏不能再有multipartResolver的配置，兩者不能共存。


1前臺JSP代碼

$(document).ready(function(){
		//初始化在線編輯器
		//設置在線編輯器上傳各類文件對應的url
		$("#newGJFrom #gjnr").xheditor({
			upLinkUrl:'${ctx}/fileupload/doXheditorUpload?flag=zip',
			upLinkExt:'zip,rar,txt',
			upImgUrl:'${ctx}/fileupload/doXheditorUpload?flag=img',
			upImgExt:'jpg,jpeg,gif,png',
			upFlashUrl:'${ctx}/fileupload/doXheditorUpload?flag=swf',
			upFlashExt:'swf',
			tools: 'Cut,Copy,Paste,Pastetext,Blocktag,Fontface,FontSize,Bold,Italic,Underline,Strikethrough,FontColor,BackColor,SelectAll,Removeformat,Align,List,Outdent,Indent,Link,Unlink,Img,Flash,Table,Source,Preview,Print,Fullscreen',
			skin: 'vista'
		});
		//刪除編輯器的 關於圖標
		$("span a[name='About']").remove();


	});


//其他代碼省略
<tr>
				<td colspan="3">
					<form:textarea name="gjnr"  path="gjnr" id="gjnr" rows="20" cols="83"/>
				</td>
			</tr>

[color=red]兼容IE6，在線編輯器需要用如下的方法去寫：[/color]
<textarea class="editor" name="gjnr" id="gjnr" name="description" rows="20" cols="83"
tools="Cut,Copy,Paste,Pastetext,Blocktag,Fontface,FontSize,Bold,Italic,Underline,Strikethrough,FontColor,BackColor,SelectAll,Removeformat,Align,List,Outdent,Indent,Link,Unlink,Img,Flash,Table,Source,Preview,Print,Fullscreen"
upLinkUrl="${ctx}/fileupload/doXheditorUpload?flag=zip" upLinkExt="zip,rar,txt,doc,docx"
upImgUrl="${ctx}/fileupload/doXheditorUpload?flag=img" upImgExt="jpg,jpeg,gif,png"
upFlashUrl="${ctx}/fileupload/doXheditorUpload?flag=swf" upFlashExt="swf"
skin="vista"></textarea>


2後臺controller 處理xheditor的文件上傳 也是利用apache的fileupload組件實現

		} catch (Exception ex) {

		printInfo(response, err, newFileName);
	}
