                                                   throws ClassNotFoundException

Deprecated. in favor of createBeanDefinition(String, String, ClassLoader)

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

createBeanDefinition

public static AbstractBeanDefinition createBeanDefinition(String parent,
                                                          String className,

Parameters:

parent - the name of the parent bean, if any

className - the name of the bean class, 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

generateBeanName

public static String generateBeanName(AbstractBeanDefinition beanDefinition,
                                      BeanDefinitionRegistry beanFactory,

Throws:

BeanDefinitionStoreException - if no unique name can be generated for the given bean definition

---

generateBeanName

public static String generateBeanName(AbstractBeanDefinition beanDefinition,
                                      BeanDefinitionRegistry beanFactory)
                               throws BeanDefinitionStoreException

Generate a bean name for the given top-level 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)

Returns:

the generated bean name

Throws:

BeanDefinitionStoreException - if no unique name can be generated for the given bean definition

---

registerBeanDefinition

public static void registerBeanDefinition(BeanDefinitionHolder bdHolder,
                                          BeanDefinitionRegistry beanFactory)
                                   throws BeanDefinitionStoreException

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:

BeanDefinitionStoreException - if registration failed

---

registerWithGeneratedName

public static String registerWithGeneratedName(AbstractBeanDefinition beanDefinition,
                                               BeanDefinitionRegistry beanFactory)
                                        throws BeanDefinitionStoreException

Register the given bean definition with a generated name, unique within the given bean factory.

Parameters:

beanDefinition - the bean definition to generate a bean name for
