刪除jsf數據表中的行

我想刪除jsf數據表中的一行。我使用jsf和hibernate和spring。但刪除操作不起作用。 Customermanagedbean.java刪除jsf數據表中的行

@ManagedBean(name="CustomerMB") 
@RequestScoped 
public class Customermanagedbean implements Serializable{ 
@ManagedProperty(value="#{CustomerBoImpl}") 
ICustomerBo customerBoImpl; 
List<Customer> CustomerList; 
public int customerId; 
public String name; 
public String address; 
public String createdDate; 



public ICustomerBo getCustomerBoImpl() { 
    return customerBoImpl; 
} 
public void setCustomerBoImpl(ICustomerBo customerBoImpl) { 
    this.customerBoImpl = customerBoImpl; 
} 

public List<Customer> getCustomerList() { 
    CustomerList=new ArrayList<Customer>(); 
    CustomerList.addAll(getCustomerBoImpl().findAllCustomer()); 

    return CustomerList; 
} 



public void setCustomerList(List<Customer> customerList) { 
    CustomerList = customerList; 
} 
public String deleteCustomer(Customer customer){ 
    getCustomerBoImpl().deleteCustomer(customer); 

    return ""; 


}// getter and setter method

CustomerBoImpl.java

@Transactional(readOnly = true) 
public class CustomerBoImpl implements ICustomerBo{ 

    ICustomerDao customerDaoImpl; 



    public ICustomerDao getCustomerDaoImpl() { 
     return customerDaoImpl; 
    } 

    public void setCustomerDaoImpl(ICustomerDao customerDaoImpl) { 
     this.customerDaoImpl = customerDaoImpl; 
    } 
@Transactional(readOnly = false) 
@Override 
    public void deleteCustomer(Customer customer){ 
     getCustomerDaoImpl().deleteCustomer(customer); 
    } 

@Override 
    public List<Customer> findAllCustomer(){ 

     return getCustomerDaoImpl().findAllCustomer(); 
    } 
}

CustomerDaoImpl.java

public class CustomerDaoImpl implements ICustomerDao{ 

    private SessionFactory sessionFactory; 
    public SessionFactory getSessionFactory() { 
     return sessionFactory;} 
    public void setSessionFactory(SessionFactory sessionFactory) { 
     this.sessionFactory = sessionFactory; 
    } 
public void deleteCustomer(Customer customer){ 
     sessionFactory.openSession(); 
     getSessionFactory().getCurrentSession().delete(customer); 
    } 


    public List<Customer> findAllCustomer(){ 
     sessionFactory.openSession(); 

     List list = getSessionFactory().getCurrentSession 

().createQuery("from Customer").list(); 
     return list; 

    } 
}

有什麼不好？請幫幫我。

您是否得到任何異常？ – Ravi 2012-07-12 00:21:13

你可以嘗試通過列表''而不是方法簽名 – Mango 2012-07-12 09:01:12

檢查您的CustomerDaoImpl類的deleteCustomer方法。你可以嘗試像下面示例

public void deleteCustomer(Customer customer){ 
     getHibernateTemplate().delete(customer); 
    }

在你CustomerBoImpl類，改變這個

@Autowired 
    ICustomerDao customerDaoImpl;

解決方法是創建一個自定義類（CustomHibernateDaoSupport）和擴展「的HibernateDaoSupport」和自動線的會議工廠和您的DAO類擴展此類

 public abstract class CustomHibernateDaoSupport extends HibernateDaoSupport{  
      @Autowired 
      public void anyMethodName(SessionFactory sessionFactory){ 
       setSessionFactory(sessionFactory); 
      } 
     }

我使用的是hibernate 4.1.4，它不支持HibernateDaoSupport – samira 2012-07-14 07:24:16
