oracle - 事务超时在 Oracle 的 Hibernate 上不起作用

Question

我在为 Oracle 上的 hibernate 设置事务超时时遇到问题。它不起作用。任何人都可以帮忙吗？ “SaveOrUpdate”不会在规定的 10 秒内返回。它会挂很长时间。 我使用的是 Oracle 10r2。

hibernate 配置文件

<hibernate-configuration>
<session-factory>
    <property name="connection.driver_class">oracle.jdbc.driver.OracleDriver</property>
    <property name="connection.url">jdbc:oracle:thin:@9.9.9.9:1521:orcl</property>
    <property name="connection.username">foouser</property>
    <property name="connection.password">foopass</property>
    <property name="hibernate.c3p0.min_size">5</property>
    <property name="hibernate.c3p0.max_size">20</property>
    <property name="dialect">org.hibernate.dialect.Oracle9Dialect</property>
    <property name="current_session_context_class">thread</property>
    <!-- Disable the second-level cache  -->
    <property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property>
    <!-- Echo all executed SQL to stdout -->
    <property name="show_sql">false</property>
    <!-- Mapping files -->
    <mapping resource="foo.hbm.xml"/>
</session-factory>
</hibernate-configuration>

hibernate 类

public class foo implements Serializable
{
...
    public void save() throws Exception
    {
        Session     dbSession = null;
        Transaction tran      = null;
        try
        {
            dbSession = PersistenceMgr.getPersistenceMgr().getDbSession();
            tran      = dbSession.beginTransaction();
            tran.setTimeout(10); // 10 seconds
            dbSession.saveOrUpdate(this);
            tran.commit();
        }
        catch (HibernateException e)
        {
            if(tran!=null)
            {
                try{tran.rollback();}
                catch(HibernateException he){}
            }
            ...
        }
        finally
        {
            if( dbSession != null )
            {
                try{dbSession.close();}
                catch(HibernateException e){}
            }
        }
    }

}

需要在事务开始之前设置超时。

而不是

tran = dbSession.beginTransaction();
tran.setTimeout(10);// 10 seconds

尝试

tran = dbSession.getTransaction();
tran.setTimeout(10);
tran.begin();
