问题:

I am new to Messaging and want to know the difference between ActiveMQ, Mule, ServiceMix and Camel

Anyone knows how each of these product is different?

Thanks in advance !

EDIT: Also would like to know any good place/resource to learn these things.

回答1:

ActiveMQ is a message broker which implements the JMS API and supports a number of cross language clients and network protocols. It lets you implement queues or topics and write listeners or subscribers to respond to queue events.

Mule and ServiceMix are open source ESB (enterprise service bus). An ESB has capabilities beyond JMS: queuing is key, but so are transformation, routing, logging, security, etc.

Apache Camel is an implementation of the patterns in Enterprise Integration Patterns. It can use JMS and other components to put the ideas from that book into place.

JMS is fundamental to the other technologies, like JDBC is the foundation for Hibernate, iBatis, etc.

JMS is a Java API and a specification and TCK (part of Java EE). ActiveMQ is a particular implementation of it.

Camel can use ActiveMQ (and Camel is bundled inside the ActiveMQ broker so you can easily route to and from JMS to the other components Camel supports).

Camel doesn't use Mule or ServiceMix directly; though ServiceMix uses Camel as its preferred routing engine and EIP implementation. Camel does have a ton of different components though that use various different technologies.



回答2:

JMS is a Java messaging protocol specification.

ActiveMQ is an implementation of the above.

Camel is a message routing engine implementing Enterprise Integration Patterns. It provides a lot of predefined components. One of its key component supports JMS.

ServiceMix is an ESB implementation compatible with JBI (Java Business Integration) specification. It also provides many infrastructural features not available in Camel (like services OSGI bundle support). SM makes heavy use of Camel.

Mule is an another implementation of ESB, but not related to the Camel/ServiceMix family.



回答3:

Apache Service Mix :: Its an ESB (Enterprise Service Bus) , a JBI Container and an Integration platform.

Apache Camel: Smart Routing and Mediation Engine which implements EIP (Enterprise Integration Patterns).

Apache ActiveMQ: Its a Message Broker that implements JMS.



回答4:

Mule is a Enterprise service bus providing end to end integration solution.

ActiveMQ is message broker for queueing messages between subscriber and receiver.

ServiceMix is also a ESB i.e. Enterprise Service Bus



回答5:

Camel empowers you to define routing and mediation rules in a variety of domain-specific languages. Mule and SeriviceMix is ESB. ActiveMQ is Messaging service.



回答6:

Apache Camel is the implementation of EIP (Enterprise Integration Patterns)

ServiceMix is the product that conforms to the principles of ESB in an SOA environment.

Active MQ is as good as any other implementation of JMS API

Mule is also an ESB
