Hibernate的Session更新數據庫

Question

沒有反映我使用的Weblogic 10.3.6 + Hibernate的3和EJB 3.0

我試圖更新的實體，但它不是在數據庫中獲取更新。 沒有例外

請找到休眠的配置文件，如下

<property name="hibernate.connection.datasource">jdbc/wfAR_ConnectionDS</property> 
    <property name="hibernate.generate_statistics">true</property> 
    <property name="hibernate.hibernate.session_factory_name">wfAR_ConnectionDS</property> 
    <property name="hibernate.current_session_context_class">thread</property> 
    <property name="hibernate.dialect">org.hibernate.dialect.SQLServerDialect</property> 
    <property name="hibernate.query.factory_class">org.hibernate.hql.classic.ClassicQueryTranslatorFactory</property> 
    <property name="hibernate.connection.driver_class">com.microsoft.jdbc.sqlserver.SQLServerDriver</property> 
    <property name="hibernate.transaction.manager_lookup_class">org.hibernate.transaction.WeblogicTransactionManagerLookup</property> 
    <property name="hibernate.transaction.factory.class">org.hibernate.transaction.CMTTransactionFactory</property> 
    <property name="hibernate.transaction.auto_close_session">false</property> 
    <property name="hibernate.transaction.flush_before_completion">true</property> 
    <property name="hibernate.show_sql">true</property> 
    <property name="hibernate.use_sql_comments">true</property> 
    <property name="hibernate.format_sql">true</property> 

，我使用下面的代碼在我的EJB

@TransactionAttribute(TransactionAttributeType.REQUIRED) 
    public long updateCustomerData(ArCatCustomer customer){ 
     long id=-1; 
     Session session = sessionFactory.openSession(); 
     try{ 
      System.out.println("**************Trying to Update***********"); 
      session.update(customer); 
      //session.evict(customer); 
      session.flush(); 
      System.out.println("***********Update Finished***********"); 
     }catch(RuntimeException runExp){ 
      runExp.printStackTrace(); 
      throw runExp; 
     } finally{ 
      session.close(); 
     } 
     return id; 
    } 

更新實體，我可以看到在下面控制檯：

**************Trying to Update*********** 
Hibernate: 
    /* update 
     com.ar.flextronics.model.ArCatCustomer */ update 
      AR_catCustomer 
     set 
      SegmentID=?, 
      MepID=?, 
      ParentCustomerID=?, 
      CustomerNumber=?, 
      CustomerName=?, 
      VendorID=?, 
      LocalVATID=?, 
      [FlexCustomer-Supplier]=?, 
      VMI=?, 
      TypeOfBilling=?, 
      CreditTerms=?, 
      CustomerCurrencyID=?, 
      CreditRate=?, 
      CreditLimit=?, 
      ParentBPNumInsideCompany=?, 
      LegalEntityname=?, 
      Region=?, 
      Active=?, 
      ERPName=?, 
      ERPServer=?, 
      ERPFinanceCompanyNumber=?, 
      ERPLogisticCompanyNumber=?, 
      LastUpdate=?, 
      UpdatedBy=?, 
      CustomerTypeID=? 
     where 
      CustomerID=? 
***********Update Finished*********** 

但是數據沒有保存在數據庫。

請幫我解決。由於

Answer 1

我沒有看到在Hibernate配置屬性：

<property name="hibernate.connection.autocommit">true</property> 

由於默認配置= FALSE。設置它並檢查結果。

但是，如果你想手動做到這一點，你需要：

Transaction tx = session.beginTransaction(); 
//your code 
tx.commit(); 
session.close();
