Let's say I have following Spring config (version of Spring is 3.0.3):

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xsi:schemaLocation="http://www.springframework.org/schema/beans
   http://www.springframework.org/schema/beans/spring-beans.xsd">

   <bean id="theFactoryBean" class="wax.MyFactoryBean"/>

   <bean id="factoryBeanUser" class="wax.FactoryBeanUser">
       <!-- what should be placed here?-->
   </bean>

</beans>

I have instance of FactoryBean implementation and some other instance. I need Spring to inject to other instance FactoryBean, not the object it produces.

There are two possible ways to solve it.

First one, obvious and malfunctional:

 <bean id="factoryBeanUser" class="wax.FactoryBeanUser">
    <property name="myFactoryBean" ref="&theFactoryBean"/>
</bean>

With this config Spring throws following exception on start:

    [skipped irrelevant part]
Caused by: org.xml.sax.SAXParseException: The reference to entity "theFactoryBean" must end with the ';' delimiter.

I found this solution Spring: Getting FactoryBean object instead of FactoryBean.getObject(), this question is maked as answered and four people

java spring
