In this lesson we will learn how to create a Red Hat Fuse project using JBoss Fuse tooling which is included in Red Hat Code Ready studio and to run a Fuse project within it.
Red Hat Code Ready studio is a development environment with superior support for your entire development lifecycle.
Start by downloading Red Hat Code Ready Studio: https://developers.redhat.com/products/codeready-studio/download
Once downloaded it, execute the JAR file:
$ java -jar codereadystudio-12.14.0.GA-installer-standalone.jar
The Red Hat Code Ready studio wizard will start. Just make sure you include the Fuse tooling in the installation:
At the end of the installation, you can launch Red Hat Code Ready studio .
Creating your first Fuse project with Fuse Tooling
From the File Menu choose: File | New | Fuse Integration Project:
Then select a Target Environment, for example a Standalone Spring Boot application:
In the next UI click Finish and a simple log using Spring Boot application will be generated
Let’s check the source code which has been added:
src
└── main
├── fabric8
│ └── deployment.yml
├── java
│ └── org
│ └── mycompany
│ └── Application.java
└── resources
├── application.properties
├── logback.xml
└── spring
└── camel-context.xml
First of all, a spring-boot application Class that includes a Camel route builder to setup the Camel routes has been added:
@SpringBootApplication
@ImportResource({"classpath:spring/camel-context.xml"})
public class Application {
// must have a main method spring-boot can run
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
The above classes, imports as a Resource the following camel-context.xml file:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation=" http://www.springframework.org/schema/beans https://www.springframework.org/schema/beans/spring-beans.xsd http://camel.apache.org/schema/spring https://camel.apache.org/schema/spring/camel-spring.xsd">
<camelContext id="camel" xmlns="http://camel.apache.org/schema/spring">
<route id="simple-route">
<from id="route-timer" uri="timer://foo?period=1000"/>
<setBody id="route-setBody">
<simple>Hello World from camel-context.xml</simple>
</setBody>
<log id="route-log" message=">>> ${body}"/>
</route>
</camelContext>
</beans>
The route can be designed/edited graphically thanks to the Fuse Tooling plugin:
In order to run the application, just right-click on the Application Main class and choose “Run”.
The following log will be displayed in the Console Panel:

Running Spring Boot and Fuse as Container Image
As you can check from the pom.xml, the project includes the fabric8-maven-plugin:
<?xml version="1.0" encoding="UTF-8"?><plugin>
<groupId>org.jboss.redhat-fuse</groupId>
<artifactId>fabric8-maven-plugin</artifactId>
<version>${fuse.version}</version>
<executions>
<execution>
<goals>
<goal>resource</goal>
<goal>build</goal>
</goals>
</execution>
</executions>
</plugin>
Before triggering the execution of the plugin, make sure Docker is started:
service docker start Then from the shell you can run your project with:
mvn clean install spring-boot:run The project will start, once that the container image of it has been created:
10:59:43.577 [Camel (MyCamel) thread #2 - timer://foo] INFO simple-route - >>> Hello World from camel-context.xml 10:59:44.577 [Camel (MyCamel) thread #2 - timer://foo] INFO simple-route - >>> Hello World from camel-context.xml 10:59:45.577 [Camel (MyCamel) thread #2 - timer://foo] INFO simple-route - >>> Hello World from camel-context.xml
You can check that the project Container image is available as follows:
$ docker images
