From 46fcdc0894b58006c49f6dcfb17544b56b2fbda8 Mon Sep 17 00:00:00 2001 From: Luis Barrios Date: Tue, 10 Jan 2017 17:06:13 +0100 Subject: [PATCH] Allow InterceptHandler to specify the messages they can intercept. This allows us to improve the performance of the broker interceptor, and will make log traces more clear. - Add methods to return an unique identifier and the supported message types at the InterceptHandler interface. - Include a default implementation of the new methods in the AbstractInterceptHandler. By default, all the interceptors will be able to handle any message (same as before). - Comment verifyNoMoreInteractions() call from the BrokerInterceptorTest.testAddAndRemoveInterceptHandler(). The removeInterceptHandler() method of the broker interceptor polls the InterceptHandler, so an interaction will always exist after the call to onSubscribe(). --- .../AbstractInterceptHandler.java | 15 +++- .../HazelcastInterceptHandler.java | 5 ++ .../interception/InterceptHandler.java | 27 ++++++- .../io/moquette/interception/Interceptor.java | 4 +- .../messages/InterceptAbstractMessage.java | 2 +- .../InterceptAcknowledgedMessage.java | 2 +- .../InterceptConnectionLostMessage.java | 2 +- .../messages/InterceptDisconnectMessage.java | 2 +- .../messages/InterceptMessage.java | 10 +++ .../messages/InterceptSubscribeMessage.java | 2 +- .../messages/InterceptUnsubscribeMessage.java | 2 +- .../main/java/io/moquette/server/Server.java | 8 +- .../moquette/spi/impl/BrokerInterceptor.java | 78 ++++++++++++------- .../moquette/spi/impl/ProtocolProcessor.java | 8 +- .../spi/impl/BrokerInterceptorTest.java | 13 +++- 15 files changed, 132 insertions(+), 48 deletions(-) create mode 100644 broker/src/main/java/io/moquette/interception/messages/InterceptMessage.java diff --git a/broker/src/main/java/io/moquette/interception/AbstractInterceptHandler.java b/broker/src/main/java/io/moquette/interception/AbstractInterceptHandler.java index 09624ad9..2f8a9a63 100644 --- a/broker/src/main/java/io/moquette/interception/AbstractInterceptHandler.java +++ b/broker/src/main/java/io/moquette/interception/AbstractInterceptHandler.java @@ -15,7 +15,13 @@ */ package io.moquette.interception; -import io.moquette.interception.messages.*; +import io.moquette.interception.messages.InterceptAcknowledgedMessage; +import io.moquette.interception.messages.InterceptConnectMessage; +import io.moquette.interception.messages.InterceptConnectionLostMessage; +import io.moquette.interception.messages.InterceptDisconnectMessage; +import io.moquette.interception.messages.InterceptPublishMessage; +import io.moquette.interception.messages.InterceptSubscribeMessage; +import io.moquette.interception.messages.InterceptUnsubscribeMessage; /** * Basic abstract class usefull to avoid empty methods creation in subclasses. @@ -23,7 +29,12 @@ import io.moquette.interception.messages.*; * Created by andrea on 08/12/15. */ public abstract class AbstractInterceptHandler implements InterceptHandler { - + + @Override + public Class[] getInterceptedMessageTypes() { + return InterceptHandler.ALL_MESSAGE_TYPES; + } + @Override public void onConnect(InterceptConnectMessage msg) {} diff --git a/broker/src/main/java/io/moquette/interception/HazelcastInterceptHandler.java b/broker/src/main/java/io/moquette/interception/HazelcastInterceptHandler.java index a1b7e990..90e7b080 100644 --- a/broker/src/main/java/io/moquette/interception/HazelcastInterceptHandler.java +++ b/broker/src/main/java/io/moquette/interception/HazelcastInterceptHandler.java @@ -18,6 +18,11 @@ public class HazelcastInterceptHandler extends AbstractInterceptHandler { public HazelcastInterceptHandler(Server server){ this.hz = server.getHazelcastInstance(); } + + @Override + public String getID() { + return HazelcastInterceptHandler.class.getName() + "@" + hz.getName(); + } @Override public void onPublish(InterceptPublishMessage msg) { diff --git a/broker/src/main/java/io/moquette/interception/InterceptHandler.java b/broker/src/main/java/io/moquette/interception/InterceptHandler.java index 821ca4e9..1aeaf2f0 100644 --- a/broker/src/main/java/io/moquette/interception/InterceptHandler.java +++ b/broker/src/main/java/io/moquette/interception/InterceptHandler.java @@ -15,7 +15,13 @@ */ package io.moquette.interception; -import io.moquette.interception.messages.*; +import io.moquette.interception.messages.InterceptAcknowledgedMessage; +import io.moquette.interception.messages.InterceptConnectMessage; +import io.moquette.interception.messages.InterceptConnectionLostMessage; +import io.moquette.interception.messages.InterceptDisconnectMessage; +import io.moquette.interception.messages.InterceptPublishMessage; +import io.moquette.interception.messages.InterceptSubscribeMessage; +import io.moquette.interception.messages.InterceptUnsubscribeMessage; import io.moquette.parser.proto.messages.AbstractMessage; import io.moquette.spi.impl.subscriptions.Subscription; @@ -32,7 +38,24 @@ import io.moquette.spi.impl.subscriptions.Subscription; * @author Wagner Macedo */ public interface InterceptHandler { - + + public static final Class ALL_MESSAGE_TYPES[] = { InterceptConnectMessage.class, + InterceptDisconnectMessage.class, InterceptConnectionLostMessage.class, InterceptPublishMessage.class, + InterceptSubscribeMessage.class, InterceptUnsubscribeMessage.class, InterceptAcknowledgedMessage.class }; + + /** + * Returns the identifier of this intercept handler. + * @return + */ + String getID(); + + /** + * Returns the InterceptMessage subtypes that this handler can process.
