Jms vs activemq
We build and run our example using Maven. If not already the case, download and install Apache Maven. Click Generate Project to generate and download the Spring Boot project template.
To avoid having to manage the version compatibility of the different Spring dependencies, we will inherit the defaults from the spring-boot-starter-parent parent POM. The generated project contains Spring Boot Starters that manage the different Spring dependencies.
You can find back the exact dependency versions in Appendix F of the reference documentation. For Spring Boot 2.Spring Boot ActiveMQ Example
The spring-boot-starter-test includes the dependencies for testing Spring Boot applications with libraries that include JUnitHamcrest and Mockito. This is a convenient way to execute and transport code. For more information on Spring Boot check out the Spring Boot getting started guide. The below sections will detail how to create a sender and receiver together with their respective configurations. It is also possible to have Spring Boot autoconfigure Spring JMS using default values so that actual code that needs to be written is reduced to a bare minimum.
For sending messages we will be using the JmsTemplate which requires a reference to a ConnectionFactory. The template provides convenience methods which handle the creation and release of resources when sending or synchronously receiving messages.
In the below Sender class, the JmsTemplate is auto-wired as the actual creation of the Bean will be done in a separate SenderConfig class. In this tutorial we will use the convertAndSend method which sends the given object to the helloworld. The type of JMS message depends on the type of the object being passed.
This class is annotated with Configuration which indicates that the class can be used by the Spring IoC container as a source of bean definitions. In addition, it encapsulates various configuration parameters, many of which are vendor specific.
The JmsTemplate was originally designed to be used in combination with a J2EE container where the container would provide the necessary pooling of the JMS resources. Like with any messaging-based application, you need to create a receiver that will handle the messages that have been sent. In this guide we named the method receivebut you can name it anything you like. The JmsListener annotation creates a message listener container behind the scenes for each annotated method, using a JmsListenerContainerFactory.
By default, a bean with name jmsListenerContainerFactory is expected that we will set up in the next section. Using the destination element, we specify the destination for this listener.
In the below example we set the destination to helloworld. For testing convenience, we added a CountDownLatch. This allows the POJO to signal that a message is received. This is something you are not likely to implement in a production application. Note that we need to add the EnableJms annotation to enable support for the JmsListener annotation that was used on the Receiver.
Reason for this is that it is generally preferable to let the listener container itself handle appropriate caching within its lifecycle. We add a dedicated application. It contains a testReceive unit test case that uses the Sender to send a message to the 'helloworld. We then use the CountDownLatch from the Receiver to verify that a message was received.
In order to execute the above test, open a command prompt in the project root directory and run following Maven command:. Maven will download the dependencies, compile the code and run the unit test case. The result should be a successful build as shown below:.I decided to rewrite it to offer a wider view on the topic.
Therefore, it implements a broker architecture, meaning that messages are queued on a central node before being sent to clients. This approach makes RabbitMQ very easy to use and deploy, because advanced scenarios like routing, load balancing or persistent message queuing are supported in just a few lines of code.
ActiveMQ is in the middle ground. Like Zmq, it can be deployed with both broker and P2P topologies. Information about any other interesting message queues is also welcome.
Abie, it all comes down to your use case. Rather than relying on someone else's account of their use case, feel free to post your use case to the rabbitmq-discuss list. Asking on twitter will get you some responses too.
Best wishes, alexis. Few applications have as many tuning configurations as ActiveMQ. Some features that make ActiveMQ stand out are:. Configurable Prefetch size. Configurable threading. Configurable failover. Configurable administrative notification to producers.
The language you want to write in might be important. Although ActiveMQ does have a client for most, their C implementation is far from complete compared to the Java Library. This means some basic functionality is flaky fail-over protocol that NET doesn't seem to be all that important to the project, development is rather slowish and there doesn't seem to be any release plan. Trunk is often broken so if you do consider this, you might want to consider contributing to the project if you want things to go ahead.
Then there is ActiveMQ itself which has a lot of nice features but some very strange issues aswell. We use the Fuse Progress version of activemq for stability reasons but even then there are a couple of weird "bugs" that you want to keep in mind:.
My subjective opinion is that AMQP is fine if you really need the persistent messaging facilities and is not too concerned that the broker may be a bottleneck. ZeroMQ may be the way otherwise. I'm using zeroMQ. I wanted a simple message passing system and I don't need the complication of a broker. I also don't want a huge Java oriented enterprise system. If you want a fast, simple system and you need to support multiple languages I use C and.
If you are also interested in commercial implementations, you should take a look at Nirvana from my-channels. Nirvana is used heavily within the Financial Services industry for large scale low-latency trading and price distribution platforms. There is support for a wide range of client programming languages across the enterprise, web and mobile domains.
The clustering capabilities are extremely advanced and worth a look if transparent HA or load balancing is important for you. They offer featurewise a lot more than ZeroMQ. They have real persistent Queues, Support for transactions etc. ZeroMQ is a lightweight message orientated socket implementation.

It is also suitable for in-process asynchronous programming.Apache ActiveMQ is released under the Apache 2. On the other hand, RabbitMQ is detailed as " A messaging broker - an intermediary for messaging ".
RabbitMQ gives your applications a common platform to send and receive messages, and your messages a safe place to live until received. RabbitMQ with 5. Managing this variety requires a reliably high-throughput message-passing technology. We use Celery 's RabbitMQ implementation, and we stumbled upon a great feature called Federation that allows us to partition our task queue across any number of RabbitMQ servers and gives us the confidence that, if any single server gets backlogged, others will pitch in and distribute some of the backlogged tasks to their consumers.
The question for which Message Queue to use mentioned "availability, distributed, scalability, and monitoring". I don't think that this excludes many options already.
I does not sound like you would take advantage of Kafka 's strengths replayability, based on an even sourcing architecture. You could pick one of the AMQP options. It ticks the boxes you mentioned and on top you will get a very flexible system, that allows you to build the architecture, pick the options and trade-offs that suite your case best.
For more information about RabbitMQ, please have a look at the linked markdown I assembled. The second half explains many configuration options. It also contains links to managed hosting and to libraries though it is missing Python's - which should be Puka, I assume. I used Kafka originally because it was mandated as part of the top-level IT requirements at a Fortune client. What I found was that it was orders of magnitude more complex So for any case where utmost flexibility and resilience are part of the deal, I would use Kafka again.
But due to the complexities involved, for any time where this level of scalability is not required, I would probably just use Beanstalkd for its simplicity. I tend to find RabbitMQ to be in an uncomfortable middle place between these two extremities. Automations are what makes a CRM powerful. With Celery and RabbitMQ we've been able to make powerful automations that truly works for our clients. Such as for example, automatic daily reports, reminders for their activities, important notifications regarding their client activities and actions on the website and more.
We use Celery basically for everything that needs to be scheduled for the future, and using RabbitMQ as our Queue-broker is amazing since it fully integrates with Django and Celery storing on our database results of the tasks done so we can see if anything fails immediately. We are going to develop a microservices-based application. I am a beginner in microservices. So, I want to know which is best. If you can think in queues then RabbitMQ should be a viable solution for integrating disparate systems.
The poster child for scalable messaging systems, RabbitMQ has been used in countless large scale systems as the messaging backbone of any large cluster, and has proven itself time and again in many production settings.
Rabbit acts as our coordinator for all actions that happen during game time.Apache ActiveMQ is released under the Apache 2. It is a messaging middleware that simplifies and accelerates the integration of diverse applications and business data across multiple platforms.

RabbitMQ gives your applications a common platform to send and receive messages, and your messages a safe place to live until received. Kafka is a distributed, partitioned, replicated commit log service. It provides the functionality of a messaging system, but with a unique design.
The 0MQ lightweight messaging kernel is a library which extends the standard socket interfaces with features traditionally provided by specialised messaging middleware products. Transmit any volume of data, at any level of throughput, without losing messages or requiring other services to be always available. With SQS, you can offload the administrative burden of operating and scaling a highly available messaging cluster, while paying a low price for only what you use.
Apache Camel.Comment 3. JMS short for Java Message Service provides a mechanism for integrating applications in a loosely coupled, flexible manner. JMS delivers data asynchronously across applications on a store and forward basis. JMS has two messaging models, point to point messaging model and publisher subscriber messaging model. Producer sends the message to a specified queue within JMS provider and the only one of the consumers who listening to that queue receives that message. Point to Point Model Example Example 1 and example 2 are almost similar the only difference is example 1 creates queues within the program and the example 2 uses jndi.
Example 1. Publisher publishes the message to a specified topic within JMS provider and all the subscribers who subscribed for that topic receive the message. Note that only the active subscribers receive the message. See the original article here. Integration Zone. Over a million developers have joined DZone. Let's be friends:. DZone 's Guide to.

On the sending side, the ActiveMq connection factory needs to be created with the url of the broker. This in turn is used to create the Spring JMS connection factory and as no session cache property is supplied the default cache is one. The template is then used in turn to create the Message Sender class:.
An example sending class is below. It uses the convertandSend method of the JmsTemplate class. As there is no destination arg, the message will be sent to the default destination which was set up in the XML file:.
On the receiving side, there needs to be a listener container. The simplest example of this is the SimpleMessageListenerContainer.
