apache-camel Getting started with apache-camel Camel Domain Specific Language

Example

Camel's DSL (Domain Specific Language) is one of the features that makes Camel standout from other Integration frameworks. While some other frameworks also feature a DSL concept, typically in the form of a XML file, the DSL was in such cases always a custom based language.

Camel offers multiple DSLs in programming languages such as Java, Scala, Groovy, and in XML.

For example a simple file copy route can be done in various ways as shown in the list below

• Java DSL

  from("file:data/in").to("file:data/out");
  

• Blueprint/Spring DSL (XML)

  <route>
    <from uri="file:data/inbox"/>
    <to uri="file:data/out"/>
  </route>
  

• Scala DSL

  from "file:data/inbox" -> "file:data/out"
