• AbstractAutoProxyCreator

  public AbstractAutoProxyCreator()

方法详细资料

• setFrozen

  public void setFrozen​(boolean frozen)

  Set whether or not the proxy should be frozen, preventing advice from being added to it once it is created.

  Overridden from the super class to prevent the proxy configuration from being frozen before the proxy is created.

  覆盖:

  setFrozen 在类中 ProxyConfig

• isFrozen

  public boolean isFrozen()

  从类复制的说明: ProxyConfig
  Return whether the config is frozen, and no advice changes can be made.

  覆盖:

  isFrozen 在类中 ProxyConfig

• setAdvisorAdapterRegistry

  public void setAdvisorAdapterRegistry​(AdvisorAdapterRegistry advisorAdapterRegistry)

  Specify the AdvisorAdapterRegistry to use.

  Default is the global AdvisorAdapterRegistry.

• setCustomTargetSourceCreators

  public void setCustomTargetSourceCreators​(TargetSourceCreator... targetSourceCreators)

  Set custom TargetSourceCreators to be applied in this order. If the list is empty, or they all return null, a SingletonTargetSource will be created for each bean.

  Note that TargetSourceCreators will kick in even for target beans where no advices or advisors have been found. If a TargetSourceCreator returns a TargetSource for a specific bean, that bean will be proxied in any case.

  TargetSourceCreators can only be invoked if this post processor is used in a BeanFactory and its BeanFactoryAware callback is triggered.

  参数:

  targetSourceCreators - the list of TargetSourceCreators. Ordering is significant: The TargetSource returned from the first matching TargetSourceCreator (that is, the first that returns non-null) will be used.

• setInterceptorNames

  public void setInterceptorNames​(String... interceptorNames)

  Set the common interceptors. These must be bean names in the current factory. They can be of any advice or advisor type Spring supports.

  If this property isn't set, there will be zero common interceptors. This is perfectly valid, if "specific" interceptors such as matching Advisors are all we want.

• setApplyCommonInterceptorsFirst

  public void setApplyCommonInterceptorsFirst​(boolean applyCommonInterceptorsFirst)

  Set whether the common interceptors should be applied before bean-specific ones. Default is "true"; else, bean-specific interceptors will get applied first.

• setBeanFactory

  public void setBeanFactory​(BeanFactory beanFactory)

  从接口复制的说明: BeanFactoryAware
  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:

  setBeanFactory 在接口中 BeanFactoryAware

  参数:

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

  另请参阅:

  BeanInitializationException

• getBeanFactory

  @Nullable
  protected BeanFactory getBeanFactory()

  Return the owning BeanFactory. May be null, as this post-processor doesn't need to belong to a bean factory.

• predictBeanType

  @Nullable
  public Class<?> predictBeanType​(Class<?> beanClass,
                                  String beanName)

  从接口复制的说明: SmartInstantiationAwareBeanPostProcessor
  Predict the type of the bean to be eventually returned from this processor's InstantiationAwareBeanPostProcessor.postProcessBeforeInstantiation(java.lang.Class<?>, java.lang.String) callback.

  The default implementation returns null.

  指定者:

  predictBeanType 在接口中 SmartInstantiationAwareBeanPostProcessor

  参数:

  beanClass - the raw class of the bean

  beanName - the name of the bean

  返回:

  the type of the bean, or null if not predictable

• determineCandidateConstructors

  @Nullable
  public Constructor<?>[] determineCandidateConstructors​(Class<?> beanClass,
                                                         String beanName)

  从接口复制的说明: SmartInstantiationAwareBeanPostProcessor
  Determine the candidate constructors to use for the given bean.

  The default implementation returns null.

  指定者:

  determineCandidateConstructors 在接口中 SmartInstantiationAwareBeanPostProcessor

  参数:

  beanClass - the raw class of the bean (never null)

  beanName - the name of the bean

  返回:

  the candidate constructors, or null if none specified

• getEarlyBeanReference

  public Object getEarlyBeanReference​(Object bean,
                                      String beanName)

  从接口复制的说明: SmartInstantiationAwareBeanPostProcessor
  Obtain a reference for early access to the specified bean, typically for the purpose of resolving a circular reference.

  This callback gives post-processors a chance to expose a wrapper early - that is, before the target bean instance is fully initialized. The exposed object should be equivalent to the what BeanPostProcessor.postProcessBeforeInitialization(java.lang.Object, java.lang.String) / BeanPostProcessor.postProcessAfterInitialization(java.lang.Object, java.lang.String) would expose otherwise. Note that the object returned by this method will be used as bean reference unless the post-processor returns a different wrapper from said post-process callbacks. In other words: Those post-process callbacks may either eventually expose the same reference or alternatively return the raw bean instance from those subsequent callbacks (if the wrapper for the affected bean has been built for a call to this method already, it will be exposes as final bean reference by default).

  The default implementation returns the given bean as-is.

  指定者:

  getEarlyBeanReference 在接口中 SmartInstantiationAwareBeanPostProcessor

  参数:

  bean - the raw bean instance

  beanName - the name of the bean

  返回:

  the object to expose as bean reference (typically with the passed-in bean instance as default)

• postProcessBeforeInstantiation

  public Object postProcessBeforeInstantiation​(Class<?> beanClass,
                                               String beanName)

  从接口复制的说明: InstantiationAwareBeanPostProcessor
  Apply this BeanPostProcessor before the target bean gets instantiated. The returned bean object may be a proxy to use instead of the target bean, effectively suppressing default instantiation of the target bean.

  If a non-null object is returned by this method, the bean creation process will be short-circuited. The only further processing applied is the BeanPostProcessor.postProcessAfterInitialization(java.lang.Object, java.lang.String) callback from the configured BeanPostProcessors.

  This callback will be applied to bean definitions with their bean class, as well as to factory-method definitions in which case the returned bean type will be passed in here.

  Post-processors may implement the extended SmartInstantiationAwareBeanPostProcessor interface in order to predict the type of the bean object that they are going to return here.

  The default implementation returns null.

  指定者:

  postProcessBeforeInstantiation 在接口中 InstantiationAwareBeanPostProcessor

  参数:

  beanClass - the class of the bean to be instantiated

  beanName - the name of the bean

  返回:

  the bean object to expose instead of a default instance of the target bean, or null to proceed with default instantiation

• postProcessAfterInstantiation

  public boolean postProcessAfterInstantiation​(Object bean,
                                               String beanName)

  从接口复制的说明: InstantiationAwareBeanPostProcessor
  Perform operations after the bean has been instantiated, via a constructor or factory method, but before Spring property population (from explicit properties or autowiring) occurs.

  This is the ideal callback for performing custom field injection on the given bean instance, right before Spring's autowiring kicks in.

  The default implementation returns true.

  指定者:

  postProcessAfterInstantiation 在接口中 InstantiationAwareBeanPostProcessor

  参数:

  bean - the bean instance created, with properties not having been set yet

  beanName - the name of the bean

  返回:

  true if properties should be set on the bean; false if property population should be skipped. Normal implementations should return true. Returning false will also prevent any subsequent InstantiationAwareBeanPostProcessor instances being invoked on this bean instance.

  InstantiationAwareBeanPostProcessor.postProcessBeforeInstantiation(java.lang.Class<?>, java.lang.String)

• postProcessProperties

  public PropertyValues postProcessProperties​(PropertyValues pvs,
                                              Object bean,
                                              String beanName)

  从接口复制的说明: InstantiationAwareBeanPostProcessor
  Post-process the given property values before the factory applies them to the given bean, without any need for property descriptors.

  Implementations should return null (the default) if they provide a custom InstantiationAwareBeanPostProcessor.postProcessPropertyValues(org.springframework.beans.PropertyValues, java.beans.PropertyDescriptor[], java.lang.Object, java.lang.String) implementation, and pvs otherwise. In a future version of this interface (with InstantiationAwareBeanPostProcessor.postProcessPropertyValues(org.springframework.beans.PropertyValues, java.beans.PropertyDescriptor[], java.lang.Object, java.lang.String) removed), the default implementation will return the given pvs as-is directly.

  指定者:

  postProcessProperties 在接口中 InstantiationAwareBeanPostProcessor

  参数:

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

  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 the given bean (can be the passed-in PropertyValues instance), or null which proceeds with the existing properties but specifically continues with a call to InstantiationAwareBeanPostProcessor.postProcessPropertyValues(org.springframework.beans.PropertyValues, java.beans.PropertyDescriptor[], java.lang.Object, java.lang.String) (requiring initialized PropertyDescriptors for the current bean class)

• postProcessBeforeInitialization

  public Object postProcessBeforeInitialization​(Object bean,
                                                String beanName)

  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.

  The default implementation returns the given bean as-is.

  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

                                               Object bean,
                                               String beanName)

  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

• getCacheKey

  protected Object getCacheKey​(Class<?> beanClass,
                               @Nullable
                               String beanName)

  Build a cache key for the given bean class and bean name.

  Note: As of 4.2.3, this implementation does not return a concatenated class/name String anymore but rather the most efficient cache key possible: a plain bean name, prepended with BeanFactory.FACTORY_BEAN_PREFIX in case of a FactoryBean; or if no bean name specified, then the given bean Class as-is.

  参数:

  beanClass - the bean class

  beanName - the bean name

  返回:

  the cache key for the given class and name

• wrapIfNecessary

  protected Object wrapIfNecessary​(Object bean,
                                   String beanName,
                                   Object cacheKey)

  Wrap the given bean if necessary, i.e. if it is eligible for being proxied.

  参数:

  bean - the raw bean instance

  beanName - the name of the bean

  cacheKey - the cache key for metadata access

  返回:

  a proxy wrapping the bean, or the raw bean instance as-is

• isInfrastructureClass

  protected boolean isInfrastructureClass​(Class<?> beanClass)

  Return whether the given bean class represents an infrastructure class that should never be proxied.

  The default implementation considers Advices, Advisors and AopInfrastructureBeans as infrastructure classes.

  参数:

  beanClass - the class of the bean

  返回:

  whether the bean represents an infrastructure class

  另请参阅:

  Advice, Advisor, AopInfrastructureBean, shouldSkip(java.lang.Class<?>, java.lang.String)

• shouldSkip

  protected boolean shouldSkip​(Class<?> beanClass,
                               String beanName)

  Subclasses should override this method to return true if the given bean should not be considered for auto-proxying by this post-processor.

  Sometimes we need to be able to avoid this happening, e.g. if it will lead to a circular reference or if the existing target instance needs to be preserved. This implementation returns false unless the bean name indicates an "original instance" according to AutowireCapableBeanFactory conventions.

  参数:

  beanClass - the class of the bean

  beanName - the name of the bean

  返回:

  whether to skip the given bean

                                               String beanName)

  Create a target source for bean instances. Uses any TargetSourceCreators if set. Returns null if no custom TargetSource should be used.

  This implementation uses the "customTargetSourceCreators" property. Subclasses can override this method to use a different mechanism.

  参数:

  beanClass - the class of the bean to create a TargetSource for

  beanName - the name of the bean

  返回:

  a TargetSource for this bean

• advisorsPreFiltered

  protected boolean advisorsPreFiltered()

  Return whether the Advisors returned by the subclass are pre-filtered to match the bean's target class already, allowing the ClassFilter check to be skipped when building advisors chains for AOP invocations.

  Default is false. Subclasses may override this if they will always return pre-filtered Advisors.

  返回:

  whether the Advisors are pre-filtered

  Subclasses may choose to implement this: for example, to change the interfaces exposed.

  The default implementation is empty.

  参数:

  proxyFactory - a ProxyFactory that is already configured with TargetSource and interfaces and will be used to create the proxy immediately after this method returns
