使用t:upload标签出现异常

Alfred_Yu

<t:formvalid beforeSubmit="upload" >

<t:upload id="file_Upload" buttonText="上传文件" multi="false" name="file_Upload" uploader="sopFileListController.do?savefile" extend="" ></t:upload>

</t:formvalid>

表单中含有一个上传组件，在表单提交之前，我调用upload方法执行异步上传文件的操作，但是后台报了如下错误：

关于文件的存取，jeecg默认是会把上传的文件存在项目根目录下的upload/files目录下的，当然你也可以指定对应的目录，只要在new UploadFile后，设置basePath属性即可，如果你不想把文件以二进制的方式存放在数据库中也是可以的，只要在new UploadFile时把byteField属性设置为null即可。

具体可参见 org.jeecgframework.core.common.dao.impl.CommonDao类中的uploadFile方法。
