<script src="/js/jquery.min.js"></script>

<!-- uploadify -->

<script src="/css/uploadify/jquery.uploadify.js"></script>

<script type="text/javascript">

$(document).ready(function(){

$("#upload").uploadify({

swf:"/css/uploadify/uploadify.swf",

uploader:"/system/updHeadImage",

fileObjName:"uploadFile", // 控制器中参数名称

auto:true,

fileSizeLimit:"1024KB",

fileTypeExts:"*.jpg;*.gif;*.png;",

onUploadSuccess:function(file, result, response) {

if(result){

// 设置图片路径

$("#img").attr("src",result);

}

// 上传失败

}

});

});

</script>

</body>

</html>

5.控制器:

/**

* 修改头像

* @return

* @throws Exception

*/

@ResponseBody

@RequestMapping(value="updHeadImage")

public String updHeadImage(MultipartFile uploadFile ,HttpServletRequest request) throws Exception {

_logger.info("+++++++++++++++++++++++ 执行修改头像 操作 +++++++++++++++++++++++ ");

File targetFile;

// 存储路径

String msgUrl = "";

// 是否上传成功标志

boolean flag = false;

// 取图片的原始名称、后缀

String fileName = uploadFile.getOriginalFilename();

if(fileName != null && fileName != ""){

// 存储路径

String returnUrl = request.getScheme() + "://" + request.getServerName() + ":" + request.getServerPort() + request.getContextPath() +"/images/uploadImgs/";

// 文件存储位置

String path = request.getSession().getServletContext().getRealPath("/images/uploadImgs/");

// 文件后缀

// String fileF = fileName.substring(fileName.lastIndexOf("."), fileName.length());

// 新的文件名

// fileName = new Date().getTime()+"_"+new Random().nextInt(1000)+fileF;

String today = DateUtil.getDate(DateUtil.yyyy_M_d);

File fileToo =new File(path+"/"+today);

// 如果文件夹不存在则创建

if(!fileToo .exists() && !fileToo .isDirectory()){

fileToo .mkdir();

}

targetFile = new File(fileToo, fileName);

try {

uploadFile.transferTo(targetFile);

msgUrl = returnUrl+today+"/"+fileName;

flag = true;

} catch (Exception e) {

e.printStackTrace();

}

}

if(flag){

return msgUrl;

}

return null;

}
