createBeanDefinition

public static AbstractBeanDefinition createBeanDefinition(String className,
                                                          String parent,

                                                          ClassLoader classLoader)
                                                   throws ClassNotFoundException
Create a new RootBeanDefinition or ChildBeanDefinition for the given class name, parent, constructor arguments, and property values.

Parameters:
className - the name of the bean class, if any
parent - the name of the parent bean, if any
cargs - the constructor arguments, if any
pvs - the property values, if any
classLoader - the ClassLoader to use for loading bean classes (can be null to just register bean classes by name)
Returns:
the bean definition
Throws:
ClassNotFoundException - if the bean class could not be loaded

generateBeanName

public static String generateBeanName(AbstractBeanDefinition beanDefinition,
                                      BeanDefinitionRegistry beanFactory,
                                      boolean isInnerBean)
                               throws BeanDefinitionStoreException
Generate a bean name for the given bean definition, unique within the given bean factory.

Parameters:
beanDefinition - the bean definition to generate a bean name for
beanFactory - the bean factory that the definition is going to be registered with (to check for existing bean names)
isInnerBean - whether the given bean definition will be registered as inner bean or as top-level bean (allowing for special name generation for inner beans vs. top-level beans)
Returns:
the bean name to use
Throws:
BeanDefinitionStoreException - if no unique name can be generated for the given bean definition

registerBeanDefinition

public static void registerBeanDefinition(BeanDefinitionHolder bdHolder,
                                          BeanDefinitionRegistry beanFactory)
                                   throws BeansException
Register the given bean definition with the given bean factory.

Parameters:
bdHolder - the bean definition including name and aliases
beanFactory - the bean factory to register with
Throws:
BeansException - if registration failed
