Question

我正在使用Weblogic 10.3.6 + Hibernate 3和EJB 3.0

我正在尝试更新实体，但它没有在数据库中更新。没有例外

请找到hibernate配置文件，如下所示

<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>

我正在使用以下代码更新EJB中的实体

@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;
    }

我可以在控制台中看到以下内容：

**************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***********

但是数据没有保存在数据库中。

请帮我解决。感谢

我在你的hibernate配置属性中看不到：

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

由于默认配置= false。设置此项并检查结果。

但如果您想手动执行此操作，则需要：

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

Hibernate会话更新没有反映在数据库中
