Dynamic-Multi-Tenancy-Using-Java-Spring-Boot-Security-JWT-Rest-API-MySQL-Postgresql-full-example

I wanted a solution where multi-tenancy is achieved by having a database per tenant and all user information (username, password, client Id etc) for authentication and authorization stored in a user table in the respective tenant databases. It meant that not only did I need a multi-tenant application, but also a secure application like any other web application secured by Spring Security. I know how to use Spring Security to secure a web application and how to use Hibernate to connect to a database. The requirement further dictated that all users belonging to a tenant be stored in the tenant database and not a separate or central database. This would allow for complete data isolation for each tenant.

Oauth2Secure-microservices-architecture-apiGateway-springCloud-netflixOSS-PostgreSQL-full-demo

I wanted a solution where we can easily captured Oauth2 and Oauth2 client for the secure communication with all of the microservices. Focusing, how to achieve oauth2 full flavor into microservices architecture. User can’t access API without token. The token will be available when user given basic and authentication details to generate token for access API. All requests will consider one entry point API-Gateway but, service-to-service can communicate. The API-Gateway will dynamic routing using Zuul Netflix OSS component. Every request will check authorization when request will arrived into service and service will request authorization server to verify is either authenticate or not. The entire Meta configuration settled into the central configuration on github (You can manage on any repository).
