Bloomberg Math Expression API

Math Expression API is a set of micro-services API responsible to perform math operations.

New Features!

• Service Registration and Discovery
• RESTful APIs
• i18n added! You can use the header Accept-Language with either en or pt to see the error messages in these languages.

Tech

Math Expression API was developed using the technologies bellow:

• Java - Java 12
• Spring Boot - Spring Boot 2
• Eureka - Service Registration and Discovery
• Lombok - Lombok
• ModelMapper - Model Mapper
• Docker - Docker
• Docker-Compose - Docker Compose
• Gradle - Gradle
• JUnit5 - JUnit 5
• Mockito - Mockito
• Postman - Postman

Installation

Math Expression API need to be cloned on GitHub.

$ git clone https://github.com/vfcarmo/bloomberg.git
$ cd bloomberg

Running the application

Test the end-to-end result by starting the eureka-server first, next starting the calculator-api and then, once those have loaded, starting the math-expression.

To make this task easy, you should execute the 'build-docker.sh'.

First you should make this file executable:

$ chmod +x build-docker.sh

Then you can run this file with sudo (its necessary because the docker-compose command require it):

$ sudo ./build-docker.sh

You should wait for all services be available, after that you can make the requests for test.

In this project, the math-expression gets the result of math operation from calculator-api. We use eureka-server, which implement service registration and discovery, to be possible one service call the other one.

You can test the Math Expression API using Postman and importing the collection (MathExpression.postman_collection.json) located in the bloomberg directory.
