這是我的我index.xhtml使用模板：JSF-不能註銷

這裏是用戶控制器。註冊並登錄工作正常 - 但註銷將不適用於我的生活。
@ManagedBean
@ViewScoped
public class UserController {
// http://stackoverflow.com/a/10691832/281545
private User user;
@EJB // do not inject stateful beans !
private UserService service;
public User getUser() {
return user;
}
@PostConstruct
void init() {
// http://stackoverflow.com/questions/3406555/why-use-postconstruct
user = new User();
}
public String login() {
FacesContext context = FacesContext.getCurrentInstance();
try {
System.out.println("Pass :" + user.getPassword());
user = service.find(user.getUsername(), user.getPassword());
context.getExternalContext().getSessionMap().put("user", user);
return "/index.xhtml?faces-redirect=true";
} catch (NoResultException e) {
context.addMessage(null, new FacesMessage(
FacesMessage.SEVERITY_ERROR, "Unknown login, please try again",
null));
return null;
}
}
public String register() {
FacesContext context = FacesContext.getCurrentInstance();
user = service.register(user);
if (user.getIduser() == 0) {
context.addMessage(null, new FacesMessage(
FacesMessage.SEVERITY_ERROR, "Registration failed", null));
return null;
}
context.getExternalContext().getSessionMap().put("user", user);
return "/index.xhtml?faces-redirect=true";
}
public String logout() {
FacesContext.getCurrentInstance().getExternalContext()
.invalidateSession();
return "/index.xhtml?faces-redirect=true";
}
}
所以當登錄按鈕重定向我到索引並顯示我的登錄名和註冊送我到索引登錄的新註冊用戶，當我打的退出按鈕只剩下我盯着You are logged in as <username>。只有索引頁面和註冊頁面中應用

請定義*註銷不會爲我的生活工作*。你有什麼具體問題：方法沒有被執行，方法被執行，但會話仍然活着？ –
@LuiggiMendoza：對不起：編輯 –
通過您的描述：你能夠檢查你的註銷方法的執行？添加日誌消息來檢查是否被調用（例如'System.out.println（「註銷...」）;'。 –
