TransactionProxyFactoryBean and cast

[Keeeeg]

Hi,

The following code works fine, but I don't understand why :

applicatinContext :

	<bean id="myUsersBusinessFacadeTarget" class="com.package.my.UsersBusinessFacadeImpl" autowire="autodetect"></bean>


	<bean id="myUsersBusinessFacade" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
		<property name="transactionManager">
			<ref bean="myTransactionManager" />
		</property>
		<property name="target">
			<ref bean="myUsersBusinessFacadeTarget" />
		</property>
		<property name="transactionAttributes">
			<props>
				<prop key="*">PROPAGATION_REQUIRED</prop>
				<prop key="*get">PROPAGATION_REQUIRED, readOnly</prop>
				<prop key="*find">PROPAGATION_REQUIRED, readOnly</prop>
			</props>
		</property>
	</bean>

Java code :

    public UsersBusinessFacade getUsersBusinessFacade() {

        ServletContext sc = ......;
        return (UsersBusinessFacade) WebApplicationContextUtils.getWebApplicationContext(sc).getBean("myUsersBusinessFacade");
    }

Owing to me, myUsersBusinessFacade's type is TransactionProxyFactoryBean.
How a cast to UsersBusinessFacade type works?

Thanks for help.

Any 'FactoryBean' implementation doesn't follow the "regular" bean definition guidelines. The FactoryBean interface allows you to define the custom creation of objects if it is more difficult that just constructing a new instance.

Another example of this is the LocalSessionFactoryBean to use with Hibernate.

Check out the docs:

I missed this point.

Thank you!
