microservices
Example applications for JavaOne 2014 talk. Tested with JDK7.
Synchronous
Person
Java application, using Spring Boot. Running on Tomcat.
Usage:
- mvn clean package
- java -jar target/person-0.0.1-SNAPSHOT.jar
Invoke service:
http://localhost:7890/person?id=2
Invoke metrics:
http://localhost:7890/metrics
Address
Java application, using DropWizard. Running on Jetty.
The addresses are stored in a json file. The location of this file can be changed in AddressRepository. In an actual application this would probably a database of your choice.
Usage:
- mvn clean package
- java -jar target/address-0.0.1-SNAPSHOT.jar server address.yml
Invoke service:
http://localhost:7891/address?id=3
Invoke admin pages:
http://localhost:7892
Invoke health check:
http://localhost:7892/healthcheck
PersonAddress
Java application, using DropWizard. Running on Jetty. Calling Person and Address microservice with Jersey.
Usage:
- mvn clean package
- java -jar target/personaddress-0.0.1-SNAPSHOT.jar server personaddress.yml
Invoke service:
http://localhost:7895/personaddress?id=2
Asynchronous
Before executing the microservices, start RabbitMQ :
sudo rabbitmq-server
Person Publisher
Java application, using Spring Boot. Running on Tomcat and RabbitMQ.
Usage:
- mvn clean package
- java -jar target/person-publisher-0.0.1-SNAPSHOT.jar
Send message to queue:
http://localhost:7893/sendall
Add person to repository:
http://localhost:7893/addperson?id=4&firstName=Luke&lastName=Skywalker&adresId=1
Adding a person does not send it to queue directly. Use /sendall again.
Person Listener
Java application, using Spring Boot. Running on Tomcat and RabbitMQ.
Usage:
- mvn clean package
- java -jar target/person-listener-0.0.1-SNAPSHOT.jar
Listener does not need to be explicitly invoked, but will display messages on receival. This can be changed in PersonListenerController as it is a RestController.
Address Publisher
Java application, using Spring Boot. Running on Tomcat and RabbitMQ.
Usage:
- mvn clean package
- java -jar target/address-publisher-0.0.1-SNAPSHOT.jar
Update address and send it to queue:
http://localhost:7897/updateAddress?id=2&street=AwesomeStreet&houseNumber=2&zipCode=1230&city=SF&country=USA
Address Listener
Java application, using Spring Boot. Running on Tomcat and RabbitMQ.
Usage:
- mvn clean package
- java -jar target/address-listener-0.0.1-SNAPSHOT.jar
Listener does not need to be explicitly invoked, but will display messages on receival. This can be changed in AddressListenerController as it is a RestController.
After updating an address with the Address Publisher and waiting for the listener to be invoked, the address of the Synchronous Address and PersonAddress microservices will be updated.
