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.zuul.security.JwtAuthenticationEntryPoint.java
@Component
  • com.microservices.zuul.security.JwtTokenAuthenticationFilter.java
private final JwtConfig jwtConfig; //import com.eureka.common.security.JwtConfig;
  • com.microservices.zuul.security.SecurityTokenConfig.java
@EnableWebSecurity
@Autowired
  private JwtConfig jwtConfig; //import com.eureka.common.security.JwtConfig;
  • 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
com.sun.xml.bind: jaxb-core, jaxb-api, jaxb-impl
org.springframework.cloud: spring-cloud-dependencies
spring-boot : web, test & devtools
  • Dependencies

spring-cloud-starter-netflix-zuul

Properties
spring.application.name=eureka-server

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
