spring html5 拖拽上传多文件

注:这仅仅是一个粗略笔记。有些代码可能没用。兴许会再更新一个能够使用的版本号。不足之处,敬请见谅。

1。spring环境搭建,这里使用的是spring3的jar,须要同一时候引入common-IO 和common-fileupload的jar包。

1.1spring.XXX.xml文件配置bean

<bean id="multipartResolver"
		class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
		<property name="maxUploadSize" value="${web.maxUploadSize}" />
	</bean>
value="xxxx"依据实际情况改动。

2.html表单

<form id="uploadForm" action="data/myData4PipeiUpload" method="post" enctype="multipart/form-data">
                    <div class="upload_box">
                        <div class="upload_main">
                            <div class="upload_choose">
                                <span id="fileDragArea" class="upload_drag_area">请将文件拖拽至此处上传</span>
                                <input id="fileImage" size="30" name="fileselects[]" multiple="multiple"  type="file">
                            </div>
                            <div id="preview" class="upload_preview"></div>
                        </div>
                       
                        <div id="uploadInf" class="upload_inf"></div>
                    </div>
                    <div class="upload_box">
                        文件名2:
				<input  name="fileFieName" id="fileFieName"  />
                    </div>
                    <DIV class="modal-footer">
			        <BUTTON class="btn btn-primary" type="submit" id="submitBut3" data-dismiss="modal">上传数据文件</BUTTON>
			        </DIV>
                </form>

2.1除了普通上传的一些格式要求之外。这里要注意多文件须要name=“XXX[]” multiple=“multiple"

 <input id="fileImage" size="30" name="fileselects[]" multiple="multiple"  type="file">

2.2这里使用了upload.js和zxxFile.js。去配置相关參数

3.后台代码编写两种方式。

3.1

@RequestMapping(value = "/myData4PipeiUpload", method = RequestMethod.POST)
	public void handleRequest(HttpServletRequest request,   
            HttpServletResponse response) throws Exception {   
        // 转型为MultipartHttpRequest:   
       MultipartHttpServletRequest multipartRequest = (MultipartHttpServletRequest) request;   
      List<MultipartFile> singleFiles = multipartRequest.getFiles("fileselects[]"); 
            
        if(singleFiles!=null&&singleFiles.size()>0){
        	for(MultipartFile file: singleFiles){
		        // 获得文件名称:   
		        String filename = file.getOriginalFilename();
		        // 获得输入流:   
		        InputStream input = file.getInputStream();   
		        // 写入文件   
		        // 或者:   
		        File source = new File("d:/dd/"+filename);   
		        file.transferTo(source); 
        	}
        }
    }  
注意參数的获取要使用fileselects[]去获取列表

3.2,直接将请求名称写入到@requestParam

@RequestMapping(value = "/myData4PipeiUpload", method = RequestMethod.POST)
	public void handleRequest(@RequestParam("fileselects[]") MultipartFile[] files,HttpServletRequest request,   
			HttpServletResponse response) throws Exception {   
		           
		if(files!=null&&files.length>0){
			for(MultipartFile file: files){
				// 获得文件名称:   
				String filename = file.getOriginalFilename();
				// 获得输入流:   
				InputStream input = file.getInputStream();   
				// 写入文件   
				
				// 或者:   
				File source = new File("d:/dd/"+filename);   
				file.transferTo(source); 
			}
		}
	}  
这样子就能够再进行兴许的操作。
