方法详细资料

• setInitAnnotationType

  public void setInitAnnotationType​(Class<? extends Annotation> initAnnotationType)

  Specify the init annotation to check for, indicating initialization methods to call after configuration of a bean.

  Any custom annotation can be used, since there are no required annotation attributes. There is no default, although a typical choice is the JSR-250 PostConstruct annotation.

• setDestroyAnnotationType

  public void setDestroyAnnotationType​(Class<? extends Annotation> destroyAnnotationType)

  Specify the destroy annotation to check for, indicating destruction methods to call when the context is shutting down.

  Any custom annotation can be used, since there are no required annotation attributes. There is no default, although a typical choice is the JSR-250 PreDestroy annotation.

• setOrder

  public void setOrder​(int order)

• getOrder

  public int getOrder()

  从接口复制的说明: Ordered
  Get the order value of this object.

  Higher values are interpreted as lower priority. As a consequence, the object with the lowest value has the highest priority (somewhat analogous to Servlet load-on-startup values).

  Same order values will result in arbitrary sort positions for the affected objects.

  指定者:

  getOrder 在接口中 Ordered

  返回:

  the order value

• postProcessMergedBeanDefinition

  public void postProcessMergedBeanDefinition​(RootBeanDefinition beanDefinition,
                                              Class<?> beanType,
                                              String beanName)

  从接口复制的说明: MergedBeanDefinitionPostProcessor
  Post-process the given merged bean definition for the specified bean.

  指定者:

  postProcessMergedBeanDefinition 在接口中 MergedBeanDefinitionPostProcessor

  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

• postProcessBeforeInitialization

  public Object postProcessBeforeInitialization​(Object bean,
                                                String beanName)
                                         throws BeansException

  从接口复制的说明: BeanPostProcessor
  Apply this BeanPostProcessor to the given new bean instance before any bean initialization callbacks (like InitializingBean's afterPropertiesSet or a custom init-method). The bean will already be populated with property values. The returned bean instance may be a wrapper around the original.

  指定者:

  postProcessBeforeInitialization 在接口中 BeanPostProcessor

  参数:

  bean - the new bean instance

  beanName - the name of the bean

  返回:

  the bean instance to use, either the original or a wrapped one; if null, no subsequent BeanPostProcessors will be invoked

  抛出:

  BeansException - in case of errors

  InitializingBean.afterPropertiesSet()

• postProcessAfterInitialization

  public Object postProcessAfterInitialization​(Object bean,
                                               String beanName)
                                        throws BeansException

  从接口复制的说明: BeanPostProcessor
  Apply this BeanPostProcessor to the given new bean instance after any bean initialization callbacks (like InitializingBean's afterPropertiesSet or a custom init-method). The bean will already be populated with property values. The returned bean instance may be a wrapper around the original.

  In case of a FactoryBean, this callback will be invoked for both the FactoryBean instance and the objects created by the FactoryBean (as of Spring 2.0). The post-processor can decide whether to apply to either the FactoryBean or created objects or both through corresponding bean instanceof FactoryBean checks.

  This callback will also be invoked after a short-circuiting triggered by a InstantiationAwareBeanPostProcessor.postProcessBeforeInstantiation(java.lang.Class<?>, java.lang.String) method, in contrast to all other BeanPostProcessor callbacks.

  指定者:

  postProcessAfterInitialization 在接口中 BeanPostProcessor

  参数:

  bean - the new bean instance

  beanName - the name of the bean

  返回:

  the bean instance to use, either the original or a wrapped one; if null, no subsequent BeanPostProcessors will be invoked

  抛出:

  BeansException - in case of errors

  InitializingBean.afterPropertiesSet(), FactoryBean

• postProcessBeforeDestruction

  public void postProcessBeforeDestruction​(Object bean,
                                           String beanName)
                                    throws BeansException

  从接口复制的说明: DestructionAwareBeanPostProcessor
  Apply this BeanPostProcessor to the given bean instance before its destruction, e.g. invoking custom destruction callbacks.

  Like DisposableBean's destroy and a custom destroy method, this callback will only apply to beans which the container fully manages the lifecycle for. This is usually the case for singletons and scoped beans.

  指定者:

  postProcessBeforeDestruction 在接口中 DestructionAwareBeanPostProcessor

  参数:

  bean - the bean instance to be destroyed

  beanName - the name of the bean

  抛出:

  BeansException - in case of errors

  另请参阅:

  DisposableBean.destroy(), AbstractBeanDefinition.setDestroyMethodName(String)

• requiresDestruction

  public boolean requiresDestruction​(Object bean)

  从接口复制的说明: DestructionAwareBeanPostProcessor
  Determine whether the given bean instance requires destruction by this post-processor.

  NOTE: Even as a late addition, this method has been introduced on DestructionAwareBeanPostProcessor itself instead of on a SmartDABPP subinterface. This allows existing DestructionAwareBeanPostProcessor implementations to easily provide requiresDestruction logic while retaining compatibility with Spring <4.3, and it is also an easier onramp to declaring requiresDestruction as a Java 8 default method in Spring 5.

  If an implementation of DestructionAwareBeanPostProcessor does not provide a concrete implementation of this method, Spring's invocation mechanism silently assumes a method returning true (the effective default before 4.3, and the to-be-default in the Java 8 method in Spring 5).

  指定者:

  requiresDestruction 在接口中 DestructionAwareBeanPostProcessor

  参数:

  bean - the bean instance to check

  返回:

  true if DestructionAwareBeanPostProcessor.postProcessBeforeDestruction(java.lang.Object, java.lang.String) is supposed to be called for this bean instance eventually, or false if not needed
