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.

Method Details

instantiateWithMethodInjection

protected Object instantiateWithMethodInjection(RootBeanDefinition bd,
 @Nullable
 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

instantiateWithMethodInjection

protected Object instantiateWithMethodInjection(RootBeanDefinition bd,
 @Nullable
 String beanName,
 BeanFactory owner,
 @Nullable
 Constructor<?> ctor,
 Object... args)

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 the given constructor and parameters.

Overrides:

instantiateWithMethodInjection in class SimpleInstantiationStrategy

getActualBeanClass

public Class<?> getActualBeanClass(RootBeanDefinition bd,
 @Nullable
 String beanName,
 BeanFactory owner)

Description copied from interface: InstantiationStrategy

Determine the actual class for the given bean definition, as instantiated at runtime.
