问个spring注入的问题

Question

想问个东西，spring注入是吧比如
<property name="hwhDao" ref="hwhDao">
这样我最多就是一个dao注入
问题如果像
<bean id="sqlMapClient" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean">
    <property name="configLocation">
     <value>classpath:/com/bossgoo/test/spring/sql-map-config.xml</value>
    </property>
    <property name="dataSource" ref="dataSource"/>
</bean>
这样，我dataSource这个对象是另一个Globals类里生成的，用get方法生成得到的，
那我怎么把一个在Globals类里的方法得到的对象，注入到SqlMapClientFactoryBean的属性里去呢书上找了半天都没提到 一共分就35分了,还想省点分用,行行好,帮帮

本来打算自己写一个bean<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
        <property name="driverClassName" value="oracle.jdbc.driver.OracleDriver"/>
        <property name="url" value="jdbc:oracle:oci:@192.168.1.201:1521:jqrdbsid"/>
        <property name="username" value="jqrdb_handler"/>
        <property name="password" value="jh13579"/>
        <property name="maxActive" value="100"/>
        <property name="maxIdle" value="30"/>
        <property name="maxWait" value="1000"/>
        <property name="defaultAutoCommit" value="true"/>
        <property name="removeAbandoned" value="true"/>
        <property name="removeAbandonedTimeout" value="60"/>
</bean>也报错log4j:WARN No appenders could be found for logger (org.springframework.context.support.FileSystemXmlApplicationContext).

Answer 2

嗯,那就是我有个常量类Globals,有个方法getDataSource,可以得到dataSource对象
现在有个地方要注入
<bean id="sqlMapClient" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean"> 
    <property name="configLocation"> 
    <value>classpath:/com/bossgoo/test/spring/sql-map-config.xml </value> 
    </property> 
    <property name="dataSource" ref="dataSource"/> 
</bean> 
我怎么注,ref要填的是类名,不是方法名啊
我是不是Globals.getDataSource,这样应该名显不行吧
