아래는 현재 현재 작업하고있는 수업입니다. 당신은 내가 getViewSessionUrl (즉 actionBean.viewSessionUrl)를 호출하는 링크를 클릭 할 때 내가 뭘하려고 오전
@UrlBinding("/person/inspect/finaid/budget/manage-session-budget.page")
public class ManageSession extends AbstractAidApplicantYearSessionTab{
//The class AbstractAidApplicantYearSessionTab has a hierarchy and the last one extends from UIAction
private static final String MANAGE_JSP_FILE="person/inspect/finaid/budget/manage-session-budget.jsp" ;
@Override
@DefaultHandler
public Resolution show() {
return new MauiForwardResolution(MANAGE_JSP_FILE);
}
public ManageSession(PersonInspectorAction personInspector, String group, String title) {
super(personInspector, group, title);
}
}
@UrlBinding("/person/inspect/finaid/budget/cost-of-attendance.page")
public class CostOfAttendanceTab extends AbstractAidApplicantTab {
public String getViewSessionUrl() {
return "/person/inspect/finaid/budget/manage-session-budget.page";
}
public CostOfAttendanceTab(PersonInspectorAction personInspector, String group, String title) {
super(personInspector, group, title);
}
}
이다. 그러면 Manage- Session-budget.page (즉, ManageSession 클래스)로 이동합니다.이 클래스에는 show()라는 기본 해결책이 있습니다.이 해결책은 manage-session-budget.jsp ...로 전달합니다. 하지만 왜 그 jsp 파일 또는 sth ManageSession 페이지에 잘못되지 않습니다 모르겠어요 ...
당신은 어떤 생각이 있으십니까?
음. You 're right 'ManageSession'에는 인수가없는 생성자가 없습니다. 그래서 'CostOfAttendance'와 같은 다른 클래스는 잘 작동합니다. 심지어 기본 생성자를 ManageSession에 넣으려고했는데 site.person.inspector.finaid.AbstractAidApplicantYearSessionTab (ManageSession의 부모)에서 사용할 수있는 기본 생성자가 없다는 컴파일 시간 오류가 있습니다. AbstractAidApplicantYearSessionTab에서 동일한 작업을 수행 할 때도 부모 클래스로 계속 이동합니다. ManageSession을 제외한 다른 클래스를 변경할 권한이 없습니다. 어떻게해야합니까? – WowBow
CostOfAttendanceTab 클래스에는 arg가없는 생성자가 있습니다.이 생성자는 아무 것도없고,이 경우 Java 컴파일러가'super()'를 호출하기 때문에 생성자를 생성합니다. 인수가없는 생성자 **는 반드시 슈퍼 생성자를 첫 번째 명령어로 호출해야합니다. 수퍼 클래스에 인수가없는 생성자가 없다면 명시 적으로 다른 하나를 호출해야합니다 :'public ManageSession() {super (null, null, null); // ...}'. http://docs.oracle.com/javase/tutorial/java/javaOO/constructors.html –
죄송합니다. CostOfAttendanceTab에는 이미 생성자가 있습니다. 나는 나의 질문을 편집했다. public CostOfAttendanceTab (PersonInspectorAction personInspector, String group, String title) { super (personInspector, group, title); } – WowBow
