方法详细信息

setCallback

public void setCallback(AnnotationParserCallback callback)

set callback

参数：

callback - the callback to set

setOrder

public void setOrder(int order)

set order

参数：

order - the order

getOrder

public int getOrder()

get order

指定者：

接口 org.springframework.core.Ordered 中的 getOrder

返回：

the order

setBeanFactory

public void setBeanFactory(org.springframework.beans.factory.BeanFactory beanFactory)
                    throws org.springframework.beans.BeansException

Callback that supplies the owning factory to a bean instance.

Invoked after the population of normal bean properties but before an initialization callback such as InitializingBean.afterPropertiesSet() or a custom init-method.

指定者：

接口 org.springframework.beans.factory.BeanFactoryAware 中的 setBeanFactory

参数：

beanFactory - owning BeanFactory (never null). The bean can immediately call methods on the factory.

抛出：

org.springframework.beans.BeansException - in case of initialization errors

BeanInitializationException

postProcessBeforeInitialization

public Object postProcessBeforeInitialization(Object bean,
                                              String beanName)
                                       throws org.springframework.beans.BeansException

To parse all initialized bean from spring which has target annotation matches.

指定者：

接口 org.springframework.beans.factory.config.BeanPostProcessor 中的 postProcessBeforeInitialization

覆盖：

类 org.springframework.beans.factory.config.InstantiationAwareBeanPostProcessorAdapter 中的 postProcessBeforeInitialization

参数：

bean - original bean initialize by spring

beanName - bean name defined in spring

返回：

wrapped object by AnnotationParserCallback

抛出：

org.springframework.beans.BeansException - in case of initialization errors

postProcessMergedBeanDefinition

public void postProcessMergedBeanDefinition(org.springframework.beans.factory.support.RootBeanDefinition beanDefinition,
                                            Class beanType,
                                            String beanName)

Post-process the given merged bean definition for the specified bean.

指定者：

接口 org.springframework.beans.factory.support.MergedBeanDefinitionPostProcessor 中的 postProcessMergedBeanDefinition

参数：

beanDefinition - the merged bean definition for the bean

beanType - the actual type of the managed bean instance

beanName - the name of the bean

postProcessPropertyValues

public org.springframework.beans.PropertyValues postProcessPropertyValues(org.springframework.beans.PropertyValues pvs,
                                                                          PropertyDescriptor[] pds,
                                                                          Object bean,

Post-process the given property values before the factory applies them to the given bean. Allows for checking whether all dependencies have been satisfied, for example based on a "Required" annotation on bean property setters.

Also allows for replacing the property values to apply, typically through creating a new MutablePropertyValues instance based on the original PropertyValues, adding or removing specific values.

指定者：

接口 org.springframework.beans.factory.config.InstantiationAwareBeanPostProcessor 中的 postProcessPropertyValues

覆盖：

类 org.springframework.beans.factory.config.InstantiationAwareBeanPostProcessorAdapter 中的 postProcessPropertyValues

参数：

pvs - the property values that the factory is about to apply (never null)

pds - the relevant property descriptors for the target bean (with ignored dependency types - which the factory handles specifically - already filtered out)

bean - the bean instance created, but whose properties have not yet been set

beanName - the name of the bean

返回：

the actual property values to apply to to the given bean (can be the passed-in PropertyValues instance), or null to skip property population

抛出：

org.springframework.beans.BeansException - in case of errors
