An example of spring boot application with rabbitmq and spring amqp

• Install rabbitmq

  You can use a docker image or install on a VM using VirtualBox. This is the procedure for centos 7.

  yum -y update yum -y install epel-release yum -y install gcc gcc-c++ glibc-devel make ncurses-devel openssl-devel autoconf java-1.8.0-openjdk-devel git wget wxBase.x86_64

  wget http://packages.erlang-solutions.com/erlang-solutions-1.0-1.noarch.rpm rpm -Uvh erlang-solutions-1.0-1.noarch.rpm yum -y update yum -y install erlang

  wget https://www.rabbitmq.com/releases/rabbitmq-server/v3.6.1/rabbitmq-server-3.6.1-1.noarch.rpm rpm --import https://www.rabbitmq.com/rabbitmq-signing-key-public.asc yum -y install rabbitmq-server-3.6.1-1.noarch.rpm

• Configure rabbitmq

  chkconfig --list chkconfig rabbitmq-server on systemctl start rabbitmq-server

  rabbitmqctl add_user admin admin rabbitmqctl set_user_tags admin administrator rabbitmqctl set_permissions -p / admin "." "." ".*"

  rabbitmqctl add_user darty darty rabbitmqctl add_vhost darty-vhost rabbitmqctl set_permissions -p darty-vhost darty "." "." "." rabbitmqctl set_permissions -p darty-vhost admin "." "." "."

  rabbitmq-plugins enable rabbitmq_management

• Rabbitmq web management

  You can access the rabbitmq management interface on our browser : http://<your_vm_ip>:15672 user/pwd : darty/darty or admin/admin

• Launch consumers/publishers

  Use your beloved java editor or on the command line :

  In your local maven repository or project target folder launch:

  nohup java -jar order-creator-0.0.1-SNAPSHOT.jar&

  nohup java -jar order-validator-0.0.1-SNAPSHOT.jar&

  nohup java -jar order-finalizer-0.0.1-SNAPSHOT.jar&

  nohup java -jar order-emailer-0.0.1-SNAPSHOT.jar&

  nohup java -jar order-injector-0.0.1-SNAPSHOT.jar&

  to kill all : pkill -f order*jar

• The use case

  • step 1 : order-creator creates orders
  • step 2 : order-validator validates the orders
  • step 3 : order-finalizer finalize the orders
  • step 4 : we are adding a new consumer for sending emails : order-emailer

  order-injector is used to inject order creation messages
