Retry Logic in Spring Boot

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.

Why we need Retry logic in our application:

• Handling temporary network issues.
• Dealing with intermittent service downtimes.
• Ensuring robustness and resilience of applications.

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)
