Camel Spring

When Camel meets Spring is a sample demonstrating how Apache Camel works with Spring Boot, with hawtio http://hawt.io/getstarted/, a modular web console let you manage, monitor your Java stuff. Check:

http://localhost:8080/hawtio/index.html

Prerequisites

• JDK 1.8, http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

• Gradle latest version, http://gradle.org

Development

• Ready, Set, Go

$ $GRADLE_HOME/bin/gradle --parallel --max-workers=2 clean build

$ $GRADLE_HOME/bin/gradle bootRun

$ $GRADLE_HOME/bin/gradle bootRun --debug-jvm

$ SERVER_PORT=8081 $GRADLE_HOME/bin/gradle bootRun

$ SPRING_PROFILES_ACTIVE=default $GRADLE_HOME/bin/gradle bootRun

$ SPRING_PROFILES_ACTIVE=elk $GRADLE_HOME/bin/gradle bootRun

$ $JAVA_HOME/bin/java -jar build/libs/camel-spring-1.0-SNAPSHOT.jar

In Fish shell, run like

𝜆 env server.port=8081 $GRADLE_HOME/bin/gradle bootRun

𝜆 env spring.profiles.active=default $GRADLE_HOME/bin/gradle bootRun

𝜆 env spring.profiles.active=elk $GRADLE_HOME/bin/gradle bootRun

• View via Hawtio console, go to URL: http://localhost:8080/hawtio/index.html

Zipkin Tracing

Start Open Zipkin Tracing server

$ docker run -d --name zipkin -p 9411:9411 openzipkin/zipkin

$ $GRADLE_HOME/bin/gradle bootRun

Then in Camel Spring to produce a PDF file, and go to URL: http://localhost:9411/

Logging with ELK (Elastic, Logstash and Kibana)

Install and Run Elastic, Logstash and Kibana

𝜆 /usr/local/elasticsearch/bin/elasticsearch

𝜆 /usr/local/kibana/bin/kibana

𝜆 cat /usr/local/logstash/logstash-json.conf
input {
    tcp {
        port => 4560
        codec => json_lines
    }
}

output {
    elasticsearch { hosts => ["localhost:9200"] }
    stdout { codec => rubydebug }
}

𝜆 /usr/local/logstash/bin/logstash -f /usr/local/logstash/logstash-json.conf

𝜆 env spring.profiles.active=production $GRADLE_HOME/bin/gradle bootRun
