  • Method Details

    • supportsEventType

      public boolean supportsEventType(@Nonnull org.springframework.core.ResolvableType eventType)
      Specified by:
      supportsEventType in interface org.springframework.context.event.GenericApplicationListener

    • supportsSourceType

      public boolean supportsSourceType(@Nullable Class<?> sourceType)
      Specified by:
      supportsSourceType in interface org.springframework.context.event.SmartApplicationListener

    • onApplicationEvent

      public void onApplicationEvent(@Nonnull org.springframework.context.ApplicationEvent event)
      Specified by:
      onApplicationEvent in interface org.springframework.context.ApplicationListener<org.springframework.context.ApplicationEvent>

    • getOrder

      public int getOrder()
      Specified by:
      getOrder in interface org.springframework.core.Ordered
      Specified by:
      getOrder in interface org.springframework.context.event.SmartApplicationListener

    • resolveDeclaredEventTypes

      protected List<org.springframework.core.ResolvableType> resolveDeclaredEventTypes(Method method, @Nullable org.springframework.context.event.EventListener ann)

    • resolveOrder

      protected int resolveOrder(Method method)

    • processEvent

      public void processEvent(Object instance, org.springframework.context.ApplicationEvent event)
      Process the specified ApplicationEvent, checking if the condition match and handling non-null result, if any.

    • resolveArguments

      @Nullable protected Object[] resolveArguments(org.springframework.context.ApplicationEvent event)
      Resolve the method arguments to use for the specified ApplicationEvent.

      These arguments will be used to invoke the method handled by this instance. Can return null to indicate that no suitable arguments could be resolved and therefore the method should not be invoked at all for the specified event.

    • handleResult

      protected void handleResult(Object instance, Object result)

    • publishEvent

      protected void publishEvent(Object instance, @Nullable Object event)

    • shouldHandle

      protected boolean shouldHandle(org.springframework.context.ApplicationEvent event, @Nullable Object[] args)

    • doInvoke

      @Nullable protected Object doInvoke(Object instance, @Nullable Object... args)
      Invoke the event listener method with the given argument values.

    • getCondition

      @Nullable protected String getCondition()
      Return the condition to use.

      Matches the condition attribute of the EventListener annotation or any matching attribute on a composed annotation that is meta-annotated with @EventListener.

    • getDetailedErrorMessage

      protected String getDetailedErrorMessage(Object bean, String message)
      Add additional details such as the bean type and method signature to the given error message.
      Parameters:
      message - error message to append the HandlerMethod details to

    • assertTargetBean

      protected void assertTargetBean(Method method, Object targetBean, @Nullable Object[] args)
      Assert that the target bean class is an instance of the class where the given method is declared. In some cases the actual bean instance at event- processing time may be a JDK dynamic proxy (lazy initialization, prototype beans, and others). Event listener beans that require proxying should prefer class-based proxy mechanisms.

    • getInvocationErrorMessage

      protected String getInvocationErrorMessage(Object bean, String message, @Nullable Object[] resolvedArgs)

    • getResolvableType

      @Nullable protected org.springframework.core.ResolvableType getResolvableType(org.springframework.context.ApplicationEvent event)
