java热重载上下文数据源

Question

我在Tomcat7服务器上运行spring应用程序，每个客户机都有自己的数据库模式。 所有数据源都是在applicationContext数据源上定义的。xml

    <property name="maxPoolSize" value="100" />
    <property name="maxStatements" value="50" />
    <property name="minPoolSize" value="3" />
    <property name="maxIdleTime" value="30" />
    <property name="preferredTestQuery" value="SELECT 1 FROM dual" />
</bean>

<bean id="client2" class="com.mchange.v2.c3p0.ComboPooledDataSource"
    destroy-method="close">
    <property name="driverClass" value="com.mysql.jdbc.Driver" />
    <property name="jdbcUrl"
        value="jdbc:mysql://127.0.0.1:3306/client2" />
    <property name="user" value="client2" />
    <property name="password" value="pass" />
    <property name="maxPoolSize" value="100" />
    <property name="maxStatements" value="50" />
    <property name="minPoolSize" value="3" />
    <property name="maxIdleTime" value="30" />
    <property name="preferredTestQuery" value="SELECT 1 FROM dual" />
</bean>

我希望，如果在应用程序中注册了客户机，应用程序将在xml上编写新的模式（我的数据库中还有一个空模式列表要命名），然后在不重新启动tomcat服务器的情况下重新加载de applicationContext

这可能吗？或者我在尝试一些疯狂的东西

谢谢
