하지만

내 코드에서이 방법이 주석 예외가 주석, 나는 웹 브라우저 catche을 취소 시도 쿠키, 코드에서 'printIDs'문자열을 검색하고 모든 발생에 대해서도 주석을 달았습니다. face-config.xml 및 web.xml을보고 tomcat webapps 디렉토리의 webapp를 삭제하고 PC를 다시 시작합니다. 아무 도움이되지 않습니다.

SelectedItemBean 소스 :

public String submit() { 
    for (Map.Entry<Integer, Boolean> entry : selectedIDs.entrySet()) { 
     if (entry.getValue() == true) { 
      System.out.println("id: " + entry.getKey() + ", " 
        + entry.getValue()); 
      id.add(entry.getKey()); 
     } 
    } 
    System.out.println("SelectedItemBean.submit() --> " + id.size()); 
    return "selected"; 
} 

public String printIDs() { 
    int i = 0; 
    if (id.isEmpty()) 
     return null; 
    System.out.println("printIDs <--"); 
    Iterator<Integer> it = id.iterator(); 
    while (it.hasNext()) { 
     i++; 
     System.out.println(it.next()); 
    } 
    System.out.println("suma produktow: " + i + "\nprintIDs -->"); 
    pb = new ProductBean(); 
    StringParse sp = new StringParse(); 
    idList = sp.prepareInStatement(id); 
    try { 
     list = pb.getProductByID(idList, 2); 
     suma = cumputeCosts(list); 
    } catch (SQLException e) { 
     e.printStackTrace(); 
    } 
    return "TESTprintIDs"; 
} 

왜 내가이 예외가 계속?

Answer 1

SelectedItemBean에는 printIDs 필드의 접근자가 있어야합니다.

public class SelectedItemBean{ 
    private String printIDs; 

    private getPrintIDs(){ 
     return printIds; 
    } 
} 

표현식 언어는 속성 확인을 위해 getter 메서드를 사용합니다. ,

public String getPrintIDs() { //Notice new signature 
    int i = 0; 
    if (id.isEmpty()) 
     return null; 
    System.out.println("printIDs <--"); 
    Iterator<Integer> it = id.iterator(); 
    while (it.hasNext()) { 
     i++; 
     System.out.println(it.next()); 
    } 
    System.out.println("suma produktow: " + i + "\nprintIDs -->"); 
    pb = new ProductBean(); 
    StringParse sp = new StringParse(); 
    idList = sp.prepareInStatement(id); 
    try { 
     list = pb.getProductByID(idList, 2); 
     suma = cumputeCosts(list); 
    } catch (SQLException e) { 
     e.printStackTrace(); 
    } 
    return "TESTprintIDs"; 
} 

Answer 2

당신은 당신의 댓글을 달았습니다 코드를 보여주지 않았다,하지만 난 당신이

<!-- ... --> 

내가 말을해야 코멘트를 고전 XML을 사용 추측 :

는이 방식으로 기존 코드를 변경할 수 있습니다 그것은 기본적으로 EL이 주석에 있더라도 실행됩니다. 이 문제를 추가하여 전 세계적으로 EL 댓글에 해결을 비활성화 할 수 있습니다,

첫째 : 당신은이 문제에 대한 두 가지 솔루션 중 하나를 사용할 수 있습니다

<context-param> 
    <param-name>facelets.SKIP_COMMENTS</param-name> 
    <param-value>true</param-value> 
</context-param> 

당신의 web.xml 파일에.

다른 해결책은 ui:remove 태그에 주석을 묶는 것입니다.
