Example 11 with TargetSource

use of org.springframework.aop.TargetSource in project spring-framework by spring-projects.

the class ProxyFactoryBean method newPrototypeInstance.

	 * backed by an independent AdvisedSupport configuration.
	 * @return a totally independent proxy, whose advice we may manipulate in isolation
