<bean id="peopleService" class="com.tiger.service.imple.PeopleServiceBean"></bean>

	<bean id="peopleServiceBeanFactory" class="com.tiger.service.imple.PeopleServiceBeanFactory"></bean>
		
	<bean id="peopleServiceBeanFactory2" factory-bean="peopleServiceBeanFactory"
		factory-method="createPeopleServiceBean2"></bean>

package com.tiger.service.imple;

public class PeopleServiceBeanFactory
{
	public static PeopleServiceBean createPeopleServiceBean()
	{
		return new PeopleServiceBean();
	}
	
	public PeopleServiceBean createPeopleServiceBean2()
	{
		return new PeopleServiceBean();
	}
}

public class PeopleServiceBean implements PeopleService
{
	public void save()
	{
		System.out.println("我是save()方法");
	}
}

结果：

我是save()方法
