                                    java.lang.reflect.Method method,
                                    Events events)

Method Detail

supportsEventType

public boolean supportsEventType(@Nonnull
                                 org.springframework.core.ResolvableType eventType)

Specified by:

supportsEventType in interface org.springframework.context.event.GenericApplicationListener

supportsSourceType

public boolean supportsSourceType(java.lang.Class<?> sourceType)

Specified by:

supportsSourceType in interface org.springframework.context.event.GenericApplicationListener

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.context.event.GenericApplicationListener

Specified by:

getOrder in interface org.springframework.core.Ordered

resolveDeclaredEventTypes

protected java.util.List<org.springframework.core.ResolvableType> resolveDeclaredEventTypes(java.lang.reflect.Method method,
                                                                                            org.springframework.context.event.EventListener ann)

resolveOrder

protected int resolveOrder(java.lang.reflect.Method method)

processEvent

public void processEvent(java.lang.Object instance,
                         org.springframework.context.ApplicationEvent event)

Process the specified ApplicationEvent, checking if the condition match and handling non-null result, if any.

resolveArguments

protected java.lang.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(java.lang.Object instance,
                            java.lang.Object result)

publishEvent

protected void publishEvent(java.lang.Object instance,
                            java.lang.Object event)

shouldHandle

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

doInvoke

protected java.lang.Object doInvoke(java.lang.Object instance,
                                    java.lang.Object... args)

Invoke the event listener method with the given argument values.

getCondition

protected java.lang.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 java.lang.String getDetailedErrorMessage(java.lang.Object bean,
                                                   java.lang.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(java.lang.reflect.Method method,
                                java.lang.Object targetBean,
                                java.lang.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 java.lang.String getInvocationErrorMessage(java.lang.Object bean,
                                                     java.lang.String message,
                                                     java.lang.Object[] resolvedArgs)

getResolvableType

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