我正在使用 Tuckey UrlRewrite 与Struts2应用程序结合使用。

I'm using Tuckey UrlRewrite in combination with a Struts2 application.

我正在尝试将以下网址：/ promotions / abcdef-987转换为/ dopromotions / detail传递变量 ID as 987

I'm trying to convert following URL: "/promotions/abcdef-987" to "/dopromotions/detail" passing variable "ID" as 987

我的重写规则如下：

<rule> <from>^/(promoties|promotions)/([0-9a-zA-Z\-_]+)-([0-9]+)$</from> <set type="parameter" name="id">$3</set> <to>/dopromotions/detail</to> </rule>

我的Struts2 Action有以下getter和setter：

And my Struts2 Action has following getters and setters:

private Integer id; public void setId(Integer id){ this.id = id; } public Integer getId(Integer id){ return id; }

但是，永远不会输入变量。在调试时，我无法在参数或属性范围内的任何位置找到id。

However, the variable never gets entered. When debugging, I can't find "id" anywhere in the parameter or attribute scope.

我尝试删除'type =参数'。这会在属性范围中添加 id ，但不会在我的整数ID中输入

I've tried removing 'type="parameter"'. This puts "id" in the attribute scope, but it doesn't get entered in my Integer id

推荐答案

我不熟悉您正在使用的URL重写器，但您可以单独使用Struts2实现这种映射。

I'm not familiar with the URL re-writer you are using, but you can achieve this sort of mapping with Struts2 alone.

有关 NamedVariablePatternMatcher 。你需要在struts.xml中设置以下常量：

Please refer to this answer about the NamedVariablePatternMatcher. You'll need the following constants set in your struts.xml:

<constant name="struts.mapper.alwaysSelectFullNamespace" value="false"/> <constant name="struts.enable.SlashesInActionNames" value="true"/> <constant name="struts.patternMatcher" value="namedVariable"/>

然后，将您的操作映射为：

Then, map your action as:

<!-- you could also make /promotions a namespace and the action just "abcdef-{id}" --> <action name="promotions/abcdef-{id}" class="..."> ... </action>
