I see that myGoodList is List<String> and String does not have
properties named key and value. Please try defining a class named MyGood
which has getKey and getValue methods then define myGoodList as
List<MyGood>.

As you want to use inside an iterator, I think you want myGoodList as
List<List<MyGood>>.

Your suggestion is good!
My problem is solved.
However, the same error occurred when my jsp page is changed to the
following.
Please help. Thanks.

<s:iterator value="myGoodList">
  <s:radio theme="simple" name="test" list="#{key:value}"/><br>
</s:iterator>

I think you want something like

<s:iterator value="myGoodList" status="rowStatus">
    <s:radio theme="simple" name="test"
list="myGoodList[%{#rowStatus.index}]"/><br>
</s:iterator>

where myGoodList is a List<Map>

If you want to simply show radio buttons list, radio tag can do without
an iterator e.g.

<s:radio theme="simple" name="test" list="myGoodList"/>

where myGoodList should be a Map.
