DEPRECATED: a new project was created (Private repository)

The project was developed to apply concepts and experiences using a microservice architecture based on simplified investment business rules of B3 (Brazilian Investment Exchange).

B3Invest Config Server

The module is responsible for centralizing the configuration access (these configurations are public because the project is used just to study).

B3Invest Eureka Server

The module is responsible for the cloud server and service discovery.

  Default Port: 8761

B3Invest Gateway Zuul

The module is responsible for managing the request using intelligent routing when a requisition from the client Gateway Zuul is send it to the correct microservice.

 Default port: 8765

B3Invest Broker

The module represents the investment broker when the client has access and can view the B3 tickets and the respective values.

B3Invest Manager

The module that simulates the B3 Project, when the tickets are registered and controllers by the Brazilian investments.

B3Invest User

The module is responsible for the user registers.

B3Invest Oauth

The security module is responsible for controlling access from all the systems according to authentication and authorization of the user's rulers.

System Technologies

• Spring Boot: Spring Boot makes it easy to create stand-alone, production-grade Spring Applications that you can "just run"
• Spring Cloud: providing both authentication and authorization
  • Feign: for external server communications
  • Netflix Zuul: Intelligent Routing
  • Netflix Ribbon: Client-side IPC library
  • Eureka: Cloud server and service discovery
  • Hystrix: fault tolerance e timeout
• Spring Security: providing authentication and authorization security
  • oauth2: oauth2 authentication bearer JWT token system
• JUnit: Unit Test
• Spock: A wonderful Groovy framework for behavior-driven Development-BDD test
• Lombok: Annotations helper library
• H2: A fast database embedded for tests
• Redis: A open source in-memory data structure store used as a database and cache
• Swagger: Swagger open source and pro tools have helped millions of API developers, teams, and organizations deliver great APIs.
• Docker: The most famous container engine used to execute the B3Invest project with their external dependencies
