Retry Logic in Spring Boot: Spring WebFlux

In modern applications, especially those interacting with external services, transient failures are common. These failures can often be mitigated by implementing retry mechanisms. In this blog, we’ll explore how to implement retry logic in Spring Boot applications, both for traditional blocking applications and reactive applications using WebFlux.

For traditional application example please read here.

Create Spring Boot Project:

1. Create Java Maven project and replace pom.xml with this. (I am expecting you have basic understanding of spring/spring boot webflux)
