javax.el.PropertyNotFoundException: Property 'image' not found on type java.lan

[芋墨者]

jsp页面代码
<a href="javascript:;" class="file-one">点击修改头像<input type="file" name="" id="" src="${empty studentPojo.image ? 'image/avater.png' : studentPojo.image}" value="${empty studentPojo.image ? '' : studentPojo.image}" onclick="$('#fileIcon').click();" onchange="perForm.uploadThumb2('fileIcon','imgIcon','image');"/></a>

页面访问时报错：

javax.el.PropertyNotFoundException: Property 'image' not found on type java.lang.String。。。 studentPojo是什么？？？后台怎么写的？？？？

[110成成]

你后台封装的实体类.image是一个对象吗？
