方法详细资料

• getOrder

  public int getOrder()

  Get the order value for the contained bean.

  As of Spring Framework 5.2, the order value is lazily retrieved using the following algorithm and cached. Note, however, that a @ControllerAdvice bean that is configured as a scoped bean — for example, as a request-scoped or session-scoped bean — will not be eagerly resolved. Consequently, Ordered is not honored for scoped @ControllerAdvice beans.

  • If the resolved bean implements Ordered, use the value returned by Ordered.getOrder().
  • If the bean type is known, use the value returned by OrderUtils.getOrder(Class, int) with Ordered.LOWEST_PRECEDENCE used as the default order value.
  • Otherwise use Ordered.LOWEST_PRECEDENCE as the default, fallback order value.

  指定者:

  getOrder 在接口中 Ordered

  返回:

  the order value

  resolveBean()

• getBeanType

  @Nullable
  public Class<?> getBeanType()

  Return the type of the contained bean.

  If the bean type is a CGLIB-generated class, the original user-defined class is returned.

• resolveBean

  public Object resolveBean()

  Get the bean instance for this ControllerAdviceBean, if necessary resolving the bean name through the BeanFactory.

  As of Spring Framework 5.2, once the bean instance has been resolved it will be cached if it is a singleton, thereby avoiding repeated lookups in the BeanFactory.

• isApplicableToBeanType

  public boolean isApplicableToBeanType​(@Nullable
                                        Class<?> beanType)

  Check whether the given bean type should be advised by this ControllerAdviceBean.

  参数:

  beanType - the type of the bean to check

• findAnnotatedBeans

  public static List<ControllerAdviceBean> findAnnotatedBeans​(ApplicationContext context)
