hibernateProperties.cfg - 从 Java 访问休眠属性

Question

我的会话工厂是这样用 XML 描述的：

>    <session-factory>
>         <property name="dialect">org.hibernate.dialect.MySQLDialect</property>
>         <property name="connection.driver_class">com.mysql.jdbc.Driver</property>
>         <property name="hibernate.c3p0.min_size">3</property>
>         <property name="hibernate.c3p0.max_size">45</property>
>         <property name="hibernate.c3p0.timeout">300</property><!--seconds-->
>         <property name="hibernate.c3p0.idle_test_period">10</property><!-- seconds -->
>         <property name="hibernate.c3p0.acquire_increment">3</property>
>         <property name="hibernate.c3p0.autoCommitOnClose">true</property>

>         </property>
>         <property name="cache.use_query_cache">false</property>
>         <property name="cache.use_minimal_puts">false</property>

是否可以从我的 Java 代码中访问 CUSTON 属性，我尝试了以下方法：

 Environment.getProperties().getProperty("CUSTOM")

或者来自 sessionFactory 对象但没有成功，无论如何我可以做到这一点？

Answer 1

试试这个代码

Field f = SessionFactoryImpl.class.getDeclaredField("properties");
f.setAccessible(true);
Properties p = (Properties)f.get(sessionFactory);
Object custom = p.get("CUSTOM");
