What patterns can I use to incorporate server-provided retry-after headers in Spring Retry configurations

Question

How can we use patterns to incorporate server-provided retry-after headers in spring retry configurations?

Answer 1

You can use the Custom BackOffPolicy pattern in Spring Retry to incorporate server-provided Retry-After headers dynamically. You can follow the steps below:

• Add Spring Retry Dependency:
• Custom BackOffPolicy
• Retry Configuration:

Here is the code implementation of the above steps:

In the code steps above, we are using RetryAfterBackOffPolicy to Reads Retry-After from headers and calculate the backoff time; Dynamic Backoff ensures delays are aligned with server instructions and Integration uses @Retryable to apply retries with custom backoff logic.
