Building a RESTful Web Service

Image
By
In this article we will cover Building RESTful web service using spring. Register developed service application to Eureka Server.

Auth-Service – RESTful application
In this application we will build authentication rest-endpoint (“/auth/login/authenticate). It will basically check userid/password is valid or not, depending on that response will be send back.
Note: For this demo application, for userid/password authentication we will check useriId==password  if this is true success response will return else un-success response will be return.
Maven Dependencies

















  • AOP for loggin-aspect
  • Config – to retrieve application config from config-server.
  • Eureka-Server – to register this service application to eureka-server.
Application Config files:
bootstrap.yml




authservice.yml



Name of the application is important as it gets register to eureka-server. Also when we look into application build using ribbon, circuit-breaker it will be important.
There is standard eureka configuration defined like eureka-server URL, renewal-interval, instanceId.


Java Code









Start application 
Execute below curl command for validating service end-point.
curl -H “Content-type:application/json” -X POST http://localhost:9092/auth/login/authenticate -d ‘{“loginId”:”123″, “password”:”123″}’
curl -H “Content-type:application/json” -X POST http://localhost:9092/auth/login/authenticate -d ‘{“loginId”:”123″, “password”:”1235″}’



As application is enabled for service-registry it will get register to eureka-server.








Cheers – Happy learning 🙂

Centralized configuration using Spring Cloud Config

By
In this blog we will be focusing on centralized configuration using  Spring Cloud Config  project. For single standalone application we can keep all required configuration bundle with application itself.  However, when we have more than one application, say in a microservice architecture, a better alternative would be to manage the configurations centrally. With the Config Server we have a central place to manage external properties for applications with support for different environments. Configuration files in several formats like YAML or properties are added to a Git repository. Features Spring Cloud Config Server features: HTTP, resource-based API for external configuration (name-value pairs, or equivalent YAML content) Encrypt and decrypt property values (symmetric or asymmetric) Embeddable easily in a Spring Boot application using  @EnableConfigServer Config Client features (for Spring applications): Bind to the Config Server and initialize...

We have seen how to setup on your linux machine here , now we will see how to perform basic CRUD operations using Spring Data & Redis server We will be creating a simple application that would persist an employee information into redis database. You will be needing certain JARs like jedis.jar, spring-data-redis.jar etc details of which you can download and view at https://github.com/meta-magic/RedisCRUDexample.git  First of all we will be creating the Employee entity, plz note that we are using the Serializable interface which automatically mapps the objects against the key.

Eureka-Server with spring cloud netflix

By
In this write-up we will focus on Service Registry – Eureka Server Rest service (auth-service application, eureka client) which register itself to registry. Web application which consumes Rest service using service registry. Service discovery  allows services to find and communicate with each other without hardcoding hostname and port. Eureka Server In spring-boot application enable the Eureka-Server by adding @EnableEurekaServer annotation to spring boot application. We have put all the configuration on GIT and this is accessed using config-server. To now more about centralized configuration (config-server) click  here eurekaserver.yml Place below bootstrap.yml in application, it basically connects to config-server and gets it required configuration. Start the spring-boot application and access eureka server using http://localhost:8760/ you will get below screen. Right now there is no application which...
