struts2中属性是可以自动封装的，给我们带来便捷性的同时，有带来了风险。

struts2标签库里，有一个submit功能的标签

<input type="submit"   value="登录"class="buttoninput"/>
<s:submit name="submit" value="提交"></s:submit>

理论上功能是和标准的input标签是相同的，但是稍不注意，添加了name属性，那就酿成大错了。

框架会自动的将submit的属性和value去往bean里面封装，但是又bean里肯定没有这个属性，这是就会报错了。

当然只要不手贱给便签加name值，就不会被强行封装上去，说道这点，也算是框架的不足把。
