In this article we shall be discussing about implementing an api gateway for our
microservices in the same service as spring security.
In my past years as a senior software engineer, I have noticed and particularly worked on
both architectural type Monolith and Microservices. From observations Microservice architecture has drastically increase it usage.
So, in this article we shall place our main focus on implementing an API gateway for our spring boot microservice architecture directly into our spring security microservice. For those not verse with spring security an article will be published related to that.
What exactly is spring security: Spring Security is a framework that provides authentication,
authorization, and protection against common attacks. With first class support for securing
both imperative and reactive applications, it is the de-facto standard for securing Spring- based applications. With this perspective instead of creating a separate microservice for our API gateway we
decided to make it up in the spring security for the following reasons:
- Centralized security model
- Performance and Latency improvement
- Enhanced Scalability and Flexibility
- Improve developer productivity
For those who have implemented API gateway precedent to December 2023 must have
noticed there was only a single module for Spring cloud gateway which was meant for
Reactive Solution (Webflux) but not MVC so later than December 2023 a new Spring cloud
gateway was introduce called Spring Cloud Gateway Server MVC built on Spring Boot and
Spring WebMvc.fn. which actually unblock the complexity of implementing an api gateway
for your MVC spring boot application.
Base on this the implementation is somehow different from the original Spring Cloud
Gateway something which was some how difficult to get the right annotations from the
beginning. To demonstrate this I have created two spring services one which is the spring
security and the other normal user services.
