Struts JSP에서 반복되는 Map 요소의 조건을 테스트하십시오.

Question

저는 Struts를 처음 사용하고 Struts 1.x를 사용하고 있습니다.

는지도가 이미 이상 반복되는

, 난 그냥 맵의 속성은, 이제 map.isGood = true 말을 할 수 있는지 확인하기 위해

<c:if> 태그를 추가해야합니다.

은 내가 그랬어 :

<c:if test=${map.isGood}> <!--do stuff--> </c:if> 

그러나 예외가 발생했습니다. 다음은지도가 정의 된 방법입니다.

<logic:iterate id="fullMap" name="fullMap" scope="request"> 
     <bean:define id="map" name="map" scope="page" toScope="request" /> 

내가 원하는 것을 어떻게 할 수 있습니까? 누구든지 도와 줄 수 있습니까?

편집 :

fullMap는지도의지도입니다. 키는 문자열이고 값은 다른 맵입니다. map은 단순한 HashMap<String, String>입니다.

Answer 1

나는 map 변수 (스트럿츠의 내 작은 이해에 따라 경찰) 값을 가지고 있다고 생각하지만 그렇지 않다. 그것은 단지 엔트리 일뿐입니다. 할 일 :

map.value['isGood'] 예상대로 작동했습니다.
