  static final String SCOPE_PROTOTYPE

  Scope identifier for the standard prototype scope: "prototype".

• ROLE_APPLICATION

  static final int ROLE_APPLICATION

  Role hint indicating that a BeanDefinition is a major part of the application. Typically corresponds to a user-defined bean.

  常量字段值

• ROLE_SUPPORT

  static final int ROLE_SUPPORT

  Role hint indicating that a BeanDefinition is a supporting part of some larger configuration, typically an outer ComponentDefinition. SUPPORT beans are considered important enough to be aware of when looking more closely at a particular ComponentDefinition, but not when looking at the overall configuration of an application.

• ROLE_INFRASTRUCTURE

  static final int ROLE_INFRASTRUCTURE

  Role hint indicating that a BeanDefinition is providing an entirely background role and has no relevance to the end-user. This hint is used when registering beans that are completely part of the internal workings of a ComponentDefinition.

方法详细资料

• setParentName

  void setParentName​(@Nullable
                     String parentName)

  Set the name of the parent definition of this bean definition, if any.

• getParentName

  @Nullable
  String getParentName()

  Return the name of the parent definition of this bean definition, if any.

• setBeanClassName

  void setBeanClassName​(@Nullable
                        String beanClassName)

  Specify the bean class name of this bean definition.

  The class name can be modified during bean factory post-processing, typically replacing the original class name with a parsed variant of it.

  setParentName(java.lang.String), setFactoryBeanName(java.lang.String), setFactoryMethodName(java.lang.String)

• getBeanClassName

  @Nullable
  String getBeanClassName()

  Return the current bean class name of this bean definition.

  Note that this does not have to be the actual class name used at runtime, in case of a child definition overriding/inheriting the class name from its parent. Also, this may just be the class that a factory method is called on, or it may even be empty in case of a factory bean reference that a method is called on. Hence, do not consider this to be the definitive bean type at runtime but rather only use it for parsing purposes at the individual bean definition level.

• setScope

  void setScope​(@Nullable
                String scope)

  Override the target scope of this bean, specifying a new scope name.

  另请参阅:

  SCOPE_SINGLETON, SCOPE_PROTOTYPE

• getScope

  @Nullable
  String getScope()

  Return the name of the current target scope for this bean, or null if not known yet.

• setLazyInit

  void setLazyInit​(boolean lazyInit)

  Set whether this bean should be lazily initialized.

  If false, the bean will get instantiated on startup by bean factories that perform eager initialization of singletons.

• isLazyInit

  boolean isLazyInit()

  Return whether this bean should be lazily initialized, i.e. not eagerly instantiated on startup. Only applicable to a singleton bean.

• setDependsOn

  void setDependsOn​(@Nullable
                    String... dependsOn)

  Set the names of the beans that this bean depends on being initialized. The bean factory will guarantee that these beans get initialized first.

• getDependsOn

  @Nullable
  String[] getDependsOn()

  Return the bean names that this bean depends on.

• setAutowireCandidate

  void setAutowireCandidate​(boolean autowireCandidate)

  Set whether this bean is a candidate for getting autowired into some other bean.

  Note that this flag is designed to only affect type-based autowiring. It does not affect explicit references by name, which will get resolved even if the specified bean is not marked as an autowire candidate. As a consequence, autowiring by name will nevertheless inject a bean if the name matches.

• isAutowireCandidate

  boolean isAutowireCandidate()

  Return whether this bean is a candidate for getting autowired into some other bean.

• setPrimary

  void setPrimary​(boolean primary)

  Set whether this bean is a primary autowire candidate.

  If this value is true for exactly one bean among multiple matching candidates, it will serve as a tie-breaker.

• isPrimary

  boolean isPrimary()

  Return whether this bean is a primary autowire candidate.

• setFactoryBeanName

  void setFactoryBeanName​(@Nullable
                          String factoryBeanName)

  Specify the factory bean to use, if any. This the name of the bean to call the specified factory method on.

  另请参阅:

  setFactoryMethodName(java.lang.String)

• getFactoryBeanName

  @Nullable
  String getFactoryBeanName()

  Return the factory bean name, if any.

• setFactoryMethodName

  void setFactoryMethodName​(@Nullable
                            String factoryMethodName)

  Specify a factory method, if any. This method will be invoked with constructor arguments, or with no arguments if none are specified. The method will be invoked on the specified factory bean, if any, or otherwise as a static method on the local bean class.

  另请参阅:

  setFactoryBeanName(java.lang.String), setBeanClassName(java.lang.String)

• getFactoryMethodName

  @Nullable
  String getFactoryMethodName()

  Return a factory method, if any.
