Overview

Order Process

API Token Authentication

Run And Test

Requirements

• JDK 22
• Gradle 8.8
• Podman & podman-compose (or Docker & docker cmopose)

Preparation

Create and run containers (PostgreSQL, RabbitMQ, Redis, Zipkin)

cd scripts
podman-compose up -d

Or use docker compose

cd scripts
sudo docker compose up -d

Run

Build and run

• eurekaServer, gateway, sbAdmin
• authServer, spProduct, spUser, spOrder, spPayment
• spWeb (web App)

cd scripts
sh run-jars.sh

Test

Add test data before run test

cd spTest
gradle clean test -i --tests AddTestData

check codes in spTest/src/test/java/xyz/defe/sp/test/AddTestData.java

Run test classes

cd spTest
gradle clean test --tests TestAllSuit

see test classes in spTest/src/test/java/xyz/defe/sp/test/*

Quick run and test

cd scripts
sh run-and-test.sh

Build docker image

Create Dockerfile

gradle dockerCreateDockerfile

It will create a Dockerfile in ./build/docker/

Build image

gradle dockerBuildImage

Podman

Execute the command before build image :

systemctl --user restart podman

Docker

Before build image, comment out this line in build.gradle file :

url = 'unix:///run/user/1000/podman/podman.sock'

When you get the following error :

Got permission denied while trying to connect to the Docker daemon socket

Add your user to docker group :

sudo groupadd docker
sudo gpasswd -a ${USER} docker
sudo systemctl restart docker
newgrp docker

Then you can running Docker without sudo, If that doesn't work, try logout or rebooting.
