Apache Camel is a powerful integration framework that simplifies connecting different systems. When combined with Spring Boot, it provides a seamless way to integrate applications with minimal boilerplate code.
In this tutorial, you will learn how to use the Apache Camel tutorial with Spring Boot, its relevance in modern applications, and how it compares to other integration tools.

How to Use Apache Camel with Spring Boot?
To use Apache Camel with Spring Boot, follow these steps:
Step 1: Add Dependencies
Include the necessary dependencies in your pom.xml (for Maven) or build.gradle (for Gradle):
Maven:
<dependency>
<groupId>org.apache.camel.springboot</groupId>
<artifactId>camel-spring-boot-starter</artifactId>
<version>3.14.0</version>
</dependency>Gradle:
dependencies {
implementation 'org.apache.camel.springboot:camel-spring-boot-starter:3.14.0'
}Step 2: Create a Camel Route
Define a Camel route using Java DSL or XML. Here’s an example using Java DSL:
import org.apache.camel.builder.RouteBuilder;
import org.springframework.stereotype.Component;
@Component
public class MyCamelRoute extends RouteBuilder {
@Override
public void configure() {
from("timer:foo?period=1000")
.log("Hello from Apache Camel in Spring Boot!");
}
}Step 3: Run the Application
Run your Spring Boot application using:
mvn spring-boot:runYou should see Camel logs indicating the route execution.
Is Apache Camel an ETL?
Yes, Apache Camel can be used for ETL (Extract, Transform, Load) processes by integrating data sources, transforming data, and routing it to different destinations.

Is Apache Camel Still Relevant?
Absolutely! Apache Camel remains a popular choice for integration due to its:
- Extensive connector support (JMS, REST, Kafka, etc.)
- Flexibility with DSLs (Java, XML, YAML, Kotlin, etc.)
- Seamless integration with Spring Boot and Microservices
How to Call a REST Service from Apache Camel?
Apache Camel can consume REST services using the rest component. Example:
from("timer:restTimer?period=5000")
.to("https://jsonplaceholder.typicode.com/posts/1")
.log("Response: ${body}");What is Better Than Apache Camel?
Alternatives to Apache Camel include:
- Spring Integration (for Java-based integrations within Spring)
- Apache NiFi (for data-driven workflows)
- MuleSoft (for enterprise API management)
- Kafka Streams (for event-driven streaming applications)
Does Spring Boot Need Apache Camel?
No, Spring Boot does not require Apache Camel, but using it simplifies integration tasks by reducing boilerplate code.
Is Apache Camel Used in Microservices?
Yes, Apache Camel is widely used in microservices architectures for message routing, transformation, and integration.
What is the New Name for ETL?
Modern ETL processes are often referred to as Data Pipelines, ELT (Extract, Load, Transform), or Data Integration Workflows.
Which Companies Are Using Apache Camel?
Several large organizations use Apache Camel, including:
- Red Hat (for Fuse and enterprise integrations)
- IBM (for hybrid cloud solutions)
- T-Mobile (for real-time messaging and routing)
- Netflix (for event-driven architecture)
Conclusion
Apache Camel, when used with Spring Boot, provides a robust and scalable way to handle system integrations. Whether for microservices, ETL, or REST API integration, it remains a relevant and powerful tool for modern applications.
