• MicroRabbit.Banking.Application
• MicroRabbit.Banking.Data
• MicroRabbit.Banking.Domain
• MicroRabbit.Transfer.Api
• MicroRabbit.Transfer.Application
• MicroRabbit.Transfer.Data
• MicroRabbit.Transfer.Domain
• MicroRabbit.MVC

Notable features

• Microservice architecture design pattern
• RabbitMQ messaging

Project notes

• MicroRabbit.Banking.Api project is listening on localhost port 5001 (https) and 5000 (http)

• MicroRabbit.Transfer.Api project is listening on localhost port 5003 (https) and 5002 (http)

• MicroRabbit.MVC project is listeing on localhost port 5005 (https) and 5004 (http)

Installation

Check if .NET Core Framework 2.2+ and SQL Server 2016+ is installed on your machine. Next configure the database connection string in appsettings.json file before creating a needed database for MicroRabbit.Banking.Api and MicroRabbit.Transfer.Api project.

To create a database for MicroRabbit.Banking.Api project, select MicroRabbit.Banking.Data in Visual Studio as >Start Project< and execute the following commands in Package Manager Console:

• Add-Migration "Initial Migration" -Context BankingDbContext
• Update-database

To create a database for MicroRabbit.Transfer.Api project, select MicroRabbit.Transfer.Data in Visual Studio as >Start Project< and execute the following commands in Package Manager Console:

• Add-Migration "Initial Migration" -Context TransferDbContext
• Update-database

After successfully created the BankingDb and the TransferDb databases you can add some test data to Accounts and TransferLogs tables. Alternatively run the MicroRabbit.Banking.Api, MicroRabbit.Transfer.Api and MicroRabbit.MVC and use swagger or MVC form input to create test data.

RabbitMQ and erlang notes

If all Api and MVC projects running correctly you can check the queued messages between sender and consumer applications by the microservices architecture design pattern with RabbitMQ.

First download and install erlang before download and install RabbitMQ on the same machine the microservcies are running. After erlang and RabbitMQ installations are done, now open RabbitMQ command prompt with administrator rights and type in the following command: rabbitmq-plugins enable rabbitmq_management

Now access the RabbitMQ admin dashboard in a browser on localhost port 1567. The default username and password for login is guest.

Other RabbitMQ commands:

• Stop app rabbitmqctl stop_app
• Start app rabbitmqctl start_app
• Reset app rabbitmqctl reset
• Add new user rabbitmqctl add_user username password
• Set new role rabbitmqctl set_user_tags username administrator
• Set new permission rabbitmqctl set_permission -p / username ".*" ".*" ".*"
