JUnit 5 Simple example
In this post under JUnit 5, I will introduce to new version of JUnit with simple example. JUnit 5 is divided into three subprojects as shown below JUnit Platform –> This is the base subproject on which other subproject depends. It has TestEngine API which will be implemented by other subprojects. Its main purpose is…… Continue reading JUnit 5 Simple example
Configuring Recovery Callback (using annotations)
In this post under Spring Retry, I will show with example how to configure a Recovery callback using annotations. Spring Retry retries fail operations for fixed number of times. If the operations fails even after last attempt, we don’t have any other option but to recover from that failure. Spring Retry provides an annotation that…… Continue reading Configuring Recovery Callback (using annotations)
Configuring exceptions to exclude from retry (using annotations)
In the previous post under Spring Retry, I showed with example how to specify the exceptions through annotation, for which a annotated operation has to be retried. In this post, I will show with example how to mention the exceptions through annotation, that when thrown by a annotated operation, Spring retry shouldn’t retry that operation.…… Continue reading Configuring exceptions to exclude from retry (using annotations)
Configuring Exceptions to include for retry (using annotations)
In this post under Spring Retry, I will show with example how to configure the exceptions for which retry has to happen. For the example I will use the below service class. Service8 1 import org.springframework.retry.annotation.Retryable; 2 import org.springframework.stereotype.Service; 3 4 @Service 5 public class Service8 { 6 private int i = 0; 7 8…… Continue reading Configuring Exceptions to include for retry (using annotations)
Configuring RetryListener (using annotations)
In this post under Spring Retry, I will show with example how to configure RetryListener using annotations. For our example we will need the below “CustomRetryListener2” class CustomRetryListener2 import org.springframework.retry.RetryCallback; import org.springframework.retry.RetryContext; import org.springframework.retry.RetryListener; import org.springframework.stereotype.Component; @Component public class CustomRetryListener2 implements RetryListener { @Override public <T, E extends Throwable> void close(RetryContext arg0, RetryCallback<T, E> arg1,…… Continue reading Configuring RetryListener (using annotations)
