無法使用@ManagedProperty顯示數據庫結果

我所問的問題可能是一個非常簡單的問題。我想在登錄成功後顯示用戶詳細信息。無法使用@ManagedProperty顯示數據庫結果

我的LoginController

public LoginController() { 
} 

public String getPassword() { 
    return password; 
} 

public String getUsername() { 
    return username; 
} 

public void setPassword(String password) { 
    this.password = password; 
} 

public void setUsername(String username) { 
    this.username = username; 
} 

public String isValidUser() { 
    String isValid="Invalid user"; 
    EntityManager em = null; 
    try { 
     em = getEntityManager(); 
     Query query = em.createNamedQuery("ClientDetails.findByClientId"); 
     query.setParameter("clientId", username); 
     //hashPassword(password); 
     ClientDetails record = (ClientDetails) query.getSingleResult(); 
     System.out.print(record); 
     String passwordHash=hashPassword(password); 
     if (record.getPassword().equals(passwordHash)) { 
      System.out.print("Valid user"); 
      isValid = "valid"; 
     } else { 
      System.out.print("InValid user"); 
      isValid="invalid"; 
     } 
    } catch (Exception e) { 
     e.printStackTrace(); 
    } finally { 
     em.close(); 
    } 
    System.out.println("Login status = " + isValid); 
    return isValid; 
} 

private EntityManager getEntityManager() { 
    return emf.createEntityManager(); 
} 

public String hashPassword(String password) { 
    String protectedPassword = null; 
    try { 
     System.out.println("password entered....." + password); 
     MessageDigest md5 = MessageDigest.getInstance("MD5"); 
     md5.update(password.getBytes()); 
     BigInteger hash = new BigInteger(1, md5.digest()); 
     protectedPassword = hash.toString(16); 
     System.out.println("password hashed....." + protectedPassword); 
    } catch (NoSuchAlgorithmException e) { 
     e.printStackTrace(); 
    } 
    return protectedPassword; 
}

兩者都託管豆nd在會話範圍內。該應用程序是Java EE 5.

我需要用戶在我的editController中輸入的用戶名。我想我使用的是錯誤的ManageProperty。你們可以指出我如何使用ManageProperty，以便我可以在我的ClientDetails POJO中將用戶名設置爲我的電子郵件字段時獲得該值。

你需要把EL-表達到ManagedProperty：

@ManagedProperty(value="#{loginController}")

確保名稱是正確的。而且LoginController有正確的註釋。

我編輯了我的問題。我做了你告訴和重定向時，我的表單是空的，沒有在表中的值 – enthusiastic 2012-01-27 11:17:51

@learner：你是否改正了'value =「＃{loginCOntroller}中的錯字？使用調試器並檢查是否屬性設置正確 – 2012-01-27 11:40:53

是的我糾正了錯字，並試過。我看不到任何用戶的具體細節正在加載... – enthusiastic 2012-01-27 11:58:13
