What is Apache Camel? | Getting Started | Components | Tooling

Get started in seconds

camel init hello.yaml
camel run hello.yaml

Or add to your existing Spring Boot project:

<dependency>
    <groupId>org.apache.camel.springboot</groupId>
    <artifactId>camel-spring-boot-starter</artifactId>
</dependency>

Write it your way

The same route in YAML, Java, or XML — pick what fits your team:

YAML:

- route:
    from:
      uri: kafka:incoming-orders
      steps:
        - unmarshal:
            json: {}
        - to:
            uri: sql:INSERT INTO orders(id, data) VALUES(:#${header.id}, :#${body})

Java:

from("kafka:incoming-orders")
    .unmarshal().json()
    .to("sql:INSERT INTO orders(id, data) VALUES(:#${header.id}, :#${body})");
