<bean id="mybean" class="com.class.mybean">
    <property name="customerName">
        <bean class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
            <property name="targetObject" ref="otherBean" />
            <property name="targetMethod" value="getCustomerName()" />
        </bean>
    </property>
</bean>

@Override
public void postProcessBeanFactory(
        ConfigurableListableBeanFactory beanFactory) throws BeansException {
        this.factory = beanFactory;

        BeanDefinitionRegistry registry = ((BeanDefinitionRegistry )factory);  
        GenericBeanDefinition beanDefinition = new GenericBeanDefinition();  
        beanDefinition.setBeanClass(MyBeanClass.class);  
        beanDefinition.setLazyInit(false);  
        beanDefinition.setAbstract(false);  
        beanDefinition.setAutowireCandidate(true);  
        //beanDefinition.setScope("session");

        values.addPropertyValue("customerName", ????);
        beanDefinition.setPropertyValues(values);
        registry.registerBeanDefinition("myDynamicBean",beanDefinition);
