How to inject config properties in Spring Boot to Spring Retry annotation?

Staring from spring-retry-1.2.0 we can use configurable properties in @Retryable annotation.

Use "maxAttemptsExpression", Refer the below code for usage,

 @Retryable(maxAttemptsExpression = "#{${my.app.maxAttempts}}", backoff = @Backoff(delayExpression = "#{${my.app. backOffDelay}}"))

It will not work if you use any version less than 1.2.0.Also you don't require any configurable property classes.

You can also use existing beans in expression attributes.

    @Retryable(include = RuntimeException.class,           maxAttemptsExpression = "#{@retryProperties.getMaxAttempts()}",           backoff = @Backoff(delayExpression = "#{@retryProperties.getBackOffInitialInterval()}",                              maxDelayExpression = "#{@retryProperties.getBackOffMaxInterval" + "()}",                              multiplierExpression = "#{@retryProperties.getBackOffIntervalMultiplier()}"))    String perform();    @Recover    String recover(RuntimeException exception);

where

retryProperties

is your bean which holds retry related properties as in your case.

You can use Spring EL as shown below to load the properties:

@Retryable(maxAttempts="${my.app.maxAttempts}",   include=TimeoutException.class,   backoff=@Backoff(value ="${my.app.backOffDelay}"))
