Class CglibSubclassingInstantiationStrategy

java.lang.Object
  org.springframework.beans.factory.support.SimpleInstantiationStrategy
      org.springframework.beans.factory.support.CglibSubclassingInstantiationStrategy

All Implemented Interfaces:

InstantiationStrategy

---

public class CglibSubclassingInstantiationStrategy
extends SimpleInstantiationStrategy

Default object instantiation strategy for use in BeanFactories. Uses CGLIB to generate subclasses dynamically if methods need to be overridden by the container, to implement Method Injection.

Using Method Injection features requires CGLIB on the classpath. However, the core IoC container will still run without CGLIB being available.

Since:

1.1

Method Detail

instantiateWithMethodInjection

protected Object instantiateWithMethodInjection(RootBeanDefinition beanDefinition,
                                                String beanName,
                                                BeanFactory owner)

Description copied from class: SimpleInstantiationStrategy

Subclasses can override this method, which is implemented to throw UnsupportedOperationException, if they can instantiate an object with the Method Injection specified in the given RootBeanDefinition. Instantiation should use a no-arg constructor.

Overrides:

instantiateWithMethodInjection in class SimpleInstantiationStrategy
