休眠，不會持續在數據庫上的數據（參見更新3）

在我目前的Spring項目，我有我的rootCOntext.xml文件這個Hibernate配置：休眠，不會持續在數據庫上的數據（參見更新3）

public List<E> select(String orderby, String groupby) {

}

被包含在這個類：

public abstract class Dao<E> { 
    protected Class<E> clazz; 

    @Autowired 
    protected SessionFactory sessionFactory; 

    public Dao(Class<E> clazz) { 
     this.clazz = clazz; 
    } 

    public Session getCurrentSession() { 
     return sessionFactory.getCurrentSession();

任何人都可以看到這裏有什麼問題？

UPDATE

我改變我的DAO方法是：

@Transactional 
public List<E> select(String orderby, String groupby) { 
    Session sess = sessionFactory.openSession(); 
    Transaction tx = null; 
    List<E> list = null; 
    try { 
     tx = sess.beginTransaction(); 
     list = sess.createCriteria(clazz).setResultTransformer(Criteria.DISTINCT_ROOT_ENTITY).list(); 
     tx.commit(); 
    } catch (Exception e) { 
     if(tx != null) 
      tx.rollback(); 
     throw e; 
    } finally { 
     sess.close(); 
    } 
    return list; 
    //return (List<E>) this.getCurrentSession().createCriteria(clazz).setResultTransformer(Criteria.DISTINCT_ROOT_ENTITY).list(); 
}

，現在我收到此錯誤：

我猜點的如何問題我從模型層實現我的課堂之間的關係。

這是我的課：

public class Usuario { 
@Id 
@GeneratedValue(strategy=GenerationType.IDENTITY) 
private Integer id; 

@Column 
@Input 
@Text 
private String login; 

@Column 
@Input 
@Password 
private String senha; 

@Column 
@Input 
@Text 
private String nome; 

@Column 
@Input 
@Text 
private String sobrenome; 

@Column 
@Input 
@Email 
private String email; 

@OneToOne 
private Cart cesta; 

@ManyToMany 
private List<Wishlist> listas; 

@ManyToMany 
private List<Orders> pedidos; 

@ManyToMany 
@Select 
private List<Credencial> credenciais; 

@Column 
@Input 
@Date 
private java.util.Date expirationDate; 

@Column 
@Input 
@Checkbox 
private Boolean locked; 

@Column 
@Input 
@Checkbox 
private Boolean enabled; 
}

有人知道如何解決這個問題？沒有使用FetchType.EAGER作爲ManyToMany關係（如果我那樣做，應用程序甚至不會啓動，因爲我得到一個錯誤hibernate無法獲取多個包）。

更新2

我嘗試這在我的DAO方法：

@Transactional 
public List<E> select(String orderby, String groupby) { 
    Session sess = sessionFactory.openSession(); 
    Transaction tx = null; 
    List<E> list = null; 
    try { 
     tx = sess.beginTransaction(); 

     Criteria criteria = this.getCurrentSession().createCriteria(clazz); 
     if(orderby != null) 
      criteria = criteria.addOrder(Order.asc(orderby)); 
     if(groupby != null) 
      //TODO 
     for(Field field : clazz.getDeclaredFields()) { 
      if(field.isAnnotationPresent(ManyToMany.class)) 
       criteria = criteria.setFetchMode(field.getName(), FetchMode.EAGER); 
     } 
     list = criteria.list(); 

     tx.commit(); 
    } catch (Exception e) { 
     if(tx != null) 
      tx.rollback(); 
     throw e; 
    } finally { 
     sess.close(); 
    } 
    return list; 
}

，現在我得到一個在這篇文章中提到的第一個錯誤。

更新3

所以，我設法解決這個錯誤改變方法getCurrentSession() DAO類到：

public Session getCurrentSession() { 
    return sessionFactory.openSession(); 
}

但現在當我從我的形式提交的數據，他們不持久在數據庫上，儘管沒有錯誤被觸發。

你好。我想幫助你解決這個問題。是否需要使用基於xml的配置？ – Taras

是的，這是我目前正在使用的項目。 –

還需要使用Criteria API。我的意思是可以使用HQL嗎？ – Taras

有你的代碼的多個問題。讓我們從頭開始。

@Transactional不適用於您的情況。這從您複製的堆棧跟蹤中清晰可見，因爲Spring使用代理對象來實現事務性調用。正如我所看到的，你的配置應該沒問題，所以我唯一能想到的就是你使用了錯誤的註釋。

不幸的是有2個@Transactional註解，一個來自javax.transaction包，另一個來自org.springframework.transaction.annotation包。顯然，你必須使用後者，否則將無法正常工作。

第二件事，懶惰的初始化異常。發生這種情況是因爲您試圖初始化事務外的懶惰關係。

有多種方案來解決這個：

把它拿來交易
內直接與原始查詢

的第一件事會解決這個問題取它，但是它不會與第二種解決方案相比，表現非常出色。

的第一件事，你可以通過調用延遲集合的任何方法做到這一點，例如

list.getLazyCollection().size()

，或者你可以使用Hibernate的機制來做到這一點：

Hibernate.initialize(list.getLazyCollection())

唯一重要的是在交易中做到這一點。

後一種直接獲取關係的解決方案涉及到JPQL/HQL查詢或Criteria API。

我用同樣的包，你和我在我的xml配置文件中的兩個附加條目：

<context:component-scan base-package="com.mypkg.daos"/> 
<context:annotation-config/>

當您使用@Transactional和@Autowried註解的話，我想這將是添加一個好主意這兩個配置屬性。

來源

2017-02-14 23:30:29

但是我有兩個條目，在我的'applicationContext.xml'文件中，我的'web.xml'中引用了'init-param'標記，它與'org.springframework.web.servlet.DispatcherServlet'的servlet條目相關聯。我是否也需要在我的'rootContext.xml'文件中複製它們？ –

是的，我有他們複製，所以你可以給它一個 –

好吧，我這樣做，但不解決問題（發生相同的錯誤）。 –

我想這春風不能夠正確地注射SessionFactory

我將使春天註釋交易在你的XML;試着在這裏看看http://docs.spring.io/spring/docs/current/spring-framework-reference/html/transaction.html;你應該在你的配置類此@EnableTransactionManagement添加或通過在XML中添加啓用事務或本：<tx:annotation-driven/>

那我會做如下：

我會寫這個倉庫DAO

@Repository 
    public class Dao<E> { 
     protected Class<E> clazz; 

     @Autowired 
     protected SessionFactory sessionFactory; 

     public Dao(Class<E> clazz) { 
      this.clazz = clazz; 
     } 

     public Session getCurrentSession() { 
      return sessionFactory.getCurrentSession(); 
     } 
     public List<E> select(String orderby, String groupby) 
     { 
     return (List<E>) this.getCurrentSession().createCriteria(clazz).setResultTransformer(Criteria.DISTINCT_ROOT_ENTITY).list(); 
     } 
    }

然後我想創建一個服務類，我會做以下

@Service 
public class ServiceClass<E> 
{ 
    @Autowired 
    private Dao<E> repos; 

@Transactional 
public List<E> select(String orderby, String groupby) { 
    return repos.select(orderby, groupby); 
} 
}

我希望這是有用

通過我的XML配置中的'我的項目已經啓用了事務處理，並且我有'@ Transactional'註釋我的Dao和Service類。仍然不工作。 –

@KleberMota不會將事務放在DAO上，但只能在服務中使用 –

我建議嘗試設置數據源上的transactionManager的，而不是SessionFactory的，像這樣：

<bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager"> 
    <property name="dataSource" ref="dataSource"/> 
</bean>

之所以有這樣的變化可以在此link找到。此外，確保您具備以下條件：宣佈你的xml文件

<tx:annotation-driven transaction-manager="transactionManager"/>，你的情況在rootContext.xml.
<context:component-scan base-package="com.myproject"/>使豆可見的春天。
@Repository你的DAO。
@Transactional您的方法或課程級別。
1. 和4.讓Spring應用並創建具有Transaction支持的代理。

來源

2017-02-18 17:16:59 alexandrum

transactionManager不能只使用'dataSource'屬性（應用程序甚至不啓動）。如果我嘗試使用'dataSource'和'sessionFactory'，則會發生相同的錯誤。關於其他選項，所有這些選項都已經就位。 –

休眠，不會持續在數據庫上的數據（參見更新3）
