Java micro-services

Build

build all projects

./gradlew clean build

build all projects without tests

./gradlew clean build -x test

Running project

respect the following order

Redis

docker pull redis:4.0.8-alpine
docker run --name redis -p 6379:6379 redis:4.0.8-alpine

config-server

update your local path: in config-server/src/main/resources

cloud.config.server.native.search-locations: file:///${user.home}/{pathToGitRepo}/cs-games-2018-relay-cloud/config-server/config

./gradlew :config-server:bootRun -Dspring.profiles.active=native

to test it worked:
GET url: http://configUser:configPassword@localhost:8888/config/eureka-server.yml should output:

eureka:
     client:
       fetchRegistry: false
       region: default
       registerWithEureka: false
       registryFetchIntervalSeconds: 5
   server:
     port: 8082
   spring:
     application:
       name: eureka-server
     redis:
       port: 6379

eureka-server

./gradlew :eureka-server:bootRun -Dspring.profiles.active=native

to test it worked: GET url: http://discUser:discPassword@localhost:8082/eureka/apps

should output something like this:

zuul-server

./gradlew :zuul-server:bootRun -Dspring.profiles.active=native

if it work, services like authorization and communication will be available on port 9090

authorization

./gradlew :authorization:bootRun -Dspring.profiles.active=native

communication

./gradlew :communication:bootRun -Dspring.profiles.active=native

if authorization and communication works, you should be able to sendMessage and get message list

sendMessage

basic auth admiral//admiral POST url http://localhost:9090/api/communication/sendMessage

requestBody JSON

{
	"title": "title",
	"content": "this is a content",
	"recipient": "admiral",
	"sender": "admiral"
}

getMessages

basic auth admiral//admiral GET url http://localhost:9090/api/communication/messages response body

{
	"_embedded": {
		"messageList": [
			{
				"id": 1,
				"title": "title",
				"content": "this is a content",
				"recipient": "admiral",
				"sender": "admiral"
			},
			...

forbidden exception

basic auth crewman//crewman

{
	"title": "title",
	"content": "this is a content",
	"recipient": "admiral",
	"sender": "crewman"
}

should receive 403 forbidden

Additional information

Service discovery (eureka)

This simplifies communication between services. You can see an example in com.ship.communication.controller.MessageController. You don't need to use a HttpClient. Don't forget to pass the cookie.

Api gateway (zuul)

The api gateway makes all micro services accessible from the same endpoint You can add AOP for all micro services

Security

To simplify the security, we're using basic authentication. You have to synchronize the users you want to use in the application both in com.ship.zuulserver.SecurityConfig and com.ship.authorization.service.UsersService

Config server

Centralize configuration for all micro services.
