Creating JBoss Fuse Spring Boot projects with Red Hat Code Ready Studio

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 

mycompany/camel-ose-springboot-xml                     latest                       71483fb79b90        2 minutes ago       517 MB
