The Pragmatic Approach to API Versioning and Lifecycle Management In the ever-evolving landscape of software development, APIs stand as the bedrock of functionality and service integration. However, as business requirements shift and technologies advance, APIs must also evolve. This brings us to the critical topic of API versioning, a subject that intertwines with the broader API lifecycle, Service Level Agreements (SLAs), and the standard support timeframes. Let’s unpack these concepts in a straightforward manner, ensuring we’re on the same page with industry best practices. API Versioning: Embracing Change Responsibly API versioning is the method by which we introduce changes...

Decoding HTTP Status Codes In the world of REST APIs, two elements are crucial for ensuring smooth communication between client and server: status codes and resource naming. These are not just technical necessities; they are the backbone of a well-structured API. Let’s explore these aspects with a focus on practicality and clarity, drawing from established practices in the field. Use of HTTP Status Codes HTTP status codes are the universal language of the web, indicating the result of a client’s request to the server. They are the API’s method of providing feedback, and using them correctly is essential for...

Simple Retry Mechanism The simplest way to retry an asynchronous operation in Spring Boot is to use a for loop to try the operation a certain number of times. Here’s an example: @Service public class MyService { @Async public CompletableFuture<String> doSomethingAsync() { // time-consuming operation return CompletableFuture.completedFuture("Done"); } } @RestController public class MyController { @Autowired private MyService myService; @GetMapping("/retry") public CompletableFuture<String> handleRetryRequest() throws InterruptedException { int retries = 3; for (int i = 0; i < retries; i++) { try { CompletableFuture<String> future = myService.doSomethingAsync(); String result = future.get(); return CompletableFuture.completedFuture(result); } catch (Exception e) {...

Add the CloudWatch dependency to your pom.xml file: <dependency> <groupId>com.amazonaws</groupId> <artifactId>aws-java-sdk-cloudwatch</artifactId> <version>1.11.976</version> </dependency> <dependency> <groupId>io.micrometer</groupId> <artifactId>micrometer-core</artifactId> <version>1.5.5</version> </dependency> <dependency> <groupId>io.micrometer</groupId> <artifactId>micrometer-registry-cloudwatch2</artifactId> <version>1.5.5</version> </dependency> Add the following bean definition to your Spring Boot application to create the cloudWatchAsyncClient bean: @Bean public CloudWatchAsyncClient cloudWatchAsyncClient() { return CloudWatchAsyncClient.builder().build(); } This will create a new CloudWatchAsyncClient bean that can be used to send metrics to CloudWatch. Configure the metrics registry to send metrics to CloudWatch by adding the following to your application.properties file: management.metrics.export.cloudwatch2.namespace=spring-boot-metrics management.metrics.export.cloudwatch2.enabled=true management.metrics.export.cloudwatch2.batchSize=1 management.metrics.export.cloudwatch2.cloudWatchConfig.namespace=spring-boot-metrics management.metrics.export.cloudwatch2.cloudWatchConfig.cloudWatchClient=cloudWatchAsyncClient This will configure the metrics registry to export metrics...

Introduction Before we dive in, let’s first understand what OAuth is and why it is important. OAuth is an open standard for authorization that allows users to grant third-party access to their resources without sharing their passwords. It is used by many popular websites, including Google, Facebook, and Twitter, to provide secure access to their APIs. Now, let’s get started with integrating Spring Boot with Google OAuth authentication. Set up a Google API Console Project To use Google OAuth authentication, you need to set up a Google API Console project. Here’s how: Go to the Google API...

Why? One common thing I have on my projects is when the application scales up some kind of async processing needs to be done. The steps for this are usually: Check the request for proper Authority and Roles Request is Validated The request is put into some queue (JMS, RabbitMQ, Pubsub) and an uuid for this request is given to the client Some other background process (or even application) reads from the queue and process it The response is sent to a response queue The client fetches the response using the uuid I always hated is setting up the queueing...
