问题描述
我正在使用<s:url>创建类似removeAction.action?id=10的URL，该URL应该由<s:form>元素中的action属性使用.
I am using <s:url> to create a URL like removeAction.action?id=10 which should be used by the action attribute in the <s:form> element.
这里的问题是，当<s:form>转换为<form>元素时，我只能看到action属性值为action="/project/removeAction.action". id参数被修整.我想要的结果是action="/project/removeAction.action?id=10"
The issue here is when the <s:form> converts to <form> element I can only see the action attribute value as action="/project/removeAction.action". The id parameter is getting trimmed. The result I wanted is action="/project/removeAction.action?id=10"
<s:url var="actionUrl" action="removeAction" includeContext="false">
<s:param name="id" value="%{id}" />
</s:url>
<s:form action="%{actionUrl}" method="post" enctype="multipart/form-data" >
<div>
<s:file name="imgUpload"/>
<s:submit> upload </submit>
</div>
</s:form>
最近我将struts2核心版本升级到2.3.12，并且遇到了这个问题.此问题在2.3.4.1版本之后开始
Recently I upgrade the struts2 core version to 2.3.12 and I am getting this issue. This issue starts after version 2.3.4.1
我不想使用hidden属性来传递参数，因为当文件大小较大时，该参数会丢失.
And I don't want to use a hidden attribute to pass the parameter as this parameter get lost when the file size is big to upload.
有什么解决办法吗?
推荐答案
也许您可以使用通配符映射
May be you could use a wildcard mapping
<action name="removeAction\\*" class="..">
</action>
并将ID作为自身URL的一部分传递，例如:removeAction/101
And pass the id as part of the url it self.e.g: removeAction/101
请参阅 http://struts.apache.org/release /2.3.x/docs/wildcard-mappings.html
