问题描述
在struts2中,我利用了struts2中的内置OGNL,命名我的输入,如< input name ='bag [item]。property'>
哪个去了getter / setter getBag()。get(item)。setProperty(value)
我已升级到struts 2.2 .1,突然间那些不再起作用:getter永远不会被调用。
In struts2, I took advantage of built-in OGNL in struts2, naming my inputs like <input name='bag["item"].property'>
Which went to getters/setters getBag().get("item").setProperty(value)
I've upgraded to struts 2.2.1, and suddently those no longer work: the getter never gets called.
互联网完全没有在参数中使用OGNL ,如果没有人制作过复杂的表格。
The internet is utterly silent on using OGNL in parameters, as if nobody ever made complex forms.
如何取回我的地图参数?
How do I get my map-parameters back?
推荐答案
事实证明,他们强化了对参数名称的限制以提高安全性。
It turns out that they hardened restrictions on parameter names to boost security.
所以我不得不添加到我的struts.xml:
So I had to add to my struts.xml:
<interceptor-stack name="defaultStack">
<interceptor-ref name="params">
<!-- For maps to work -->
<param name="acceptParamNames">
[a-zA-Z0-9\.\]\[\(\)_'\s"/]+
</param>
</interceptor-ref>
</interceptor-stack>
(我有 s和/ s在我的参数名称中)
文件上传在此之后停止工作(拦截器堆栈是疯狂的),所以我不得不明确添加它。
(I had "s and /s in my parameter names)File upload ceased working after that (interceptor stacks are madness), so I had to add it explicity either.
更新:这些天我强烈建议使用JSON传递复杂的结构而不是丰富的OGNL表单。当然你需要一些JS。
Update: These days I strongly suggest using JSON to pass complex structures instead of rich OGNL forms. Of course you would need some JS.
