Vulgarization

Specificities in a Spring aborescence

Eureka

Is the registration service, all services will connect to the same adress: http://localhost:9000 for example

Fichiers Server Zuul Image & Gallery
Main
  • com.microservices.server.EurekaServerApplication.java
@SpringBootApplication
@EnableEurekaServer // Enable eureka server
  • com.microservices.zuul.EurekaZuulApplication.java
@SpringBootApplication
@EnableEurekaClient
@EnableZuulProxy
  • com.microservices.image.EurekaImageApplication.java
@SpringBootApplication
@EnableEurekaClient
  • com.microservices.image.controllers.ImageController.java
@RestController
@RequestMapping("/")
@Autowired
   private Environment env;
  • com.microservices.image.entities.Image.java
Pom.xml
  • Dependencies
spring-cloud-starter-netflix-eureka-server
spring-boot : web, test & devtools
  • Dependencies
groupId - org.springframework.cloud
  spring-cloud-starter-netflix-eureka-client
  spring-cloud-starter-netflix-zuul
groupId - com.microservices.common
  SpringEurekaCommon
spring-boot : web, test, devtools & security
  • Dependencies
spring-cloud-starter-netflix-eureka-client
spring-boot : web, test & devtools
Properties 
spring.application.name=eureka-server
server.port=8761
eureka.client.register-with-eureka=false
eureka.client.fetch-registry=false

server.port=8762
spring.application.name=zuul-server
eureka.client.service-url.default-zone=http://localhost:8761/eureka/
#zuul.prefix=/api
  • Disable accessing services using service name (i.e. gallery-service).
zuul.ignored-services=*
  • Map paths to services
zuul.routes.gallery-service.path=/gallery/**
zuul.routes.gallery-service.service-id=gallery-service
zuul.routes.auth-service.path=/auth/**
zuul.routes.auth-service.service-id=AUTH-SERVICE$
  • So, if request is "/gallery/view/1", gallery service will get "/view/1".
zuul.routes.auth-service.strip-prefix=false
zuul.routes.auth-service.sensitive-headers=Cookie,Set-Cookie  #Exclude authorization from sensitive headers

 spring.application.name=image-service
 server.port=8200
 eureka.client.service-url.default-zone=http://localhost:8761/eureka
Fichiers Common Auth

  • com.microservices.common.security
@Value("${security.jwt.uri:/auth/**}")
