Security First API Design with OAuth 2.0 in Spring Based Microservices
Rajeev Kumar Sharma · International Journal for Research Trends and Innovation · 2025
The increasing use of microservice has put additional strain on scalable secure API authorization frameworks/pipelines. Breach of OAuth 2.0 OAuth 2.0 is an increasingly used form of delegated authentication that introduces numerous integration challenges to Spring-based applications, especially in terms of token validation, token lifecycle and inter-service trust.This survey offers an assessment of JWT, introspection and hybridization models, validation techniques and trade-offs in conducting experiments.The article presents the weakness of revocation processes which is normally inequality in the implementation besides insecure key distribution.It proposes theoretical models and presents the analysis that empirically provides the comparative point of view that attempts to bridge the implementationpractice gap in ventilating security settings of enterprise.
