struts2拦截器的通配符访问

我有一个带通配符的动作，我想在拦截器中访问此变量

I have a action with a wildcard y I want to access to this variable in the interceptor

动作

  @Action(value="{uri}/page",
        results={
            @Result(name=SUCCESS,location="/success.jsp"),
            }
        )
  public String execute(){
    ...

拦截器

  public String intercept(ActionInvocation actionInvocation) throws Exception {
         // =( uri is not in the map
        Map<String, Object> params =
              actionInvocation.getInvocationContext().getContextMap();
   ...

我找不到在拦截器中可以找到通配符的地方

I don't find where I can get the wildcard in the interceptor

我只是找到方法:

   public String intercept(ActionInvocation actionInvocation) throws Exception {
         ActionConfig config = actionInvocation.getProxy().getConfig();
         log.info(config.getParams().get("uri"));
