Data exchanges have increased tremendously nowadays, and thus, the number of applications that should be integrated is also augmenting at a fast pace. Though the interfaces use different types of data formats, protocols and technologies, however, the integration of these applications should be supported by automatic tests and must be modelled in a standardized way. Today JVM environment facilitates developers with three integration frameworks, namely: Spring Integration, Apache Camel and Mule ESB.
These are one of the most efficient frameworks and thus, can be used in any integration project that you are carrying out within the JVM format irrespective of the fact that which data formats, protocols and technologies you are using. This blog presents an insight about these three integration frameworks to understand their pros and cons. We have compared these integration frameworks, majorly on the basis of their expandability, error handling, domain-specific languages, enterprise readiness, IDE support, deployment, testability and their basic architectures.
Spring Integration is an extension to the well known Spring project programming model with the integration support. Some of the Spring features like security, transactions, dependency injection, etc. can be easily used, but if you are already running a spring project and want to add some integration stuff in it, only then opting for Spring Integration services would be right choice.
One of the major reasons is that you do not have to struggle much to learn Spring Integration if you are aware of Spring. However, it only offers very limited support for technologies like web services, HTTP, FTP or JMS. In Spring Integration, you can use Java annotations and code for some tasks, but you would require a lot of XML for most of the things. Thus, we would recommend using this integration only when you have an existing Spring project and you only need to add some integration logic in it that requires very basic technologies.
Apache Camel Integration is quite identical to Mule but it offers a lot more components for a broad spectrum of technologies. Moreover, if a component is not available, you have the flexibility to create a component on your own with the help of Maven Archetype. Camel possesses incredible Spring Integration as well and its readability is also much better than the latter. Apache possesses many other astounding features like it offers DSLs for Scala, Groovy and Java.
Since it offers an amazing integration, I would prefer Apache Camel over Spring Integration in the majority of use cases.
Mule ESB is a full service ESB that possesses a plethora of additional features along with an incredible integration framework. Nevertheless, you can use Mule as one of the lightweight integration frameworks if you do not add or sue any additional features apart from EIP integration. It offers an astonishing and intuitive visual designer which also facilitates visual
Mule ESB Development
One of the major advantages of Mule is when you need some connectors like SAP, IBMs CICS Transaction Gateway, Paypal, Oracle Siebel, Tibco Rendezvous in your integration prefer using Mule.
Overall, all these frameworks are lightweight and easy to use for integrate your distributed applications, services & Data. You can use any of these depending on the project scenario.
