Java에서 중첩 된 map.entries 삽입하는 방법?

Question

두 번째 항목의 값을 얻고 isues를 얻으려고합니다. 귀하의 도움에 미리 감사드립니다. 이것은 내가 형식 불일치를 얻을 오류입니다

<util:map id="externalUrlMap" map-class="java.util.HashMap"> 
    <entry key="privacy">   
     <util:map map-class="java.util.HashMap"> 
      <entry key="en" value="${exit.privacy.url.en}"/> 
      <entry key="fr" value="${exit.privacy.url.fr}"/>   
     </util:map>   
    </entry> 
    <entry key="logout">   
     <util:map map-class="java.util.HashMap"> 
      <entry key="en" value="${exit.logout.url.en}"/> 
      <entry key="fr" value="${exit.logout.url.fr}"/>   
     </util:map>   
    </entry> 
</util:map> 

컨트롤러

String urlType = "privacy"; 
    // Using Iterator to loop externalUrlMap 
    Iterator<Map.Entry<String, Entry<String, String>>> entries = externalUrlMap.entrySet().iterator(); 

    // Start Iterator 
    while (entries.hasNext()) {    
      Map.Entry<String, List<String>> entry = entries.next(); 

      if (entry.getKey().equalsIgnoreCase(urlType)){ 
       String key = entry.getKey(); 
       //Object value = entry.getValue().en; 
       List<String> list = entry.getValue(); 
       //first item 
       String first = list.get(0); 
       //second item 
       String second = list.get(1); 

       System.out.println(key + "" + ""+ first +""+ second); 
      } 
    }

테스트하려면 다음과 같은 최소한의 설정을 수행했습니다. direkt 값에 액세스하는 데는 아무런 문제가 없습니다.

import java.util.Map; 

import org.springframework.context.support.GenericXmlApplicationContext; 

public class Test { 
    public static void main(String[] args) { 
     GenericXmlApplicationContext context = new GenericXmlApplicationContext("/application-context.xml"); 
     Map<String, Map<String, String>> externalUrlMap = (Map<String, Map<String, String>>)context.getBean("externalUrlMap"); 

     System.out.println(externalUrlMap.get("privacy").get("en")); 
     System.out.println(externalUrlMap.get("privacy").get("fr")); 
     System.out.println(externalUrlMap.get("logout").get("en")); 
     System.out.println(externalUrlMap.get("logout").get("fr")); 


    } 
}
