“Evaluation Driven Development (EDD) is the Swiss army knife for your RAG pipelines. LlamaIndex offers a comprehensive list of options in its Evaluation Modules to help you choose the right implementation strategy for your use case. EDD to RAG pipeline development is TDD to Java/Spring development.”
“Strategy design pattern is a behavioral design pattern which can be useful when you have multiple ways of performing an action. For example, imagine you have a notification application that allows users to notify for their notifications using different methods, such as SMS, email, Whatsapp. You could use the Strategy pattern to implement each method as a separate strategy class. Then, at runtime, you could inject the appropriate strategy class into your application and use it to process the notifications.”
“Metrics are quantifiable measurements that provide a view into the performance, behavior, and health of an application. In the age of microservices and distributed applications, real-time metrics can be a lifesaver when diagnosing issues or understanding application behavior. Metrics can help identify bottlenecks or inefficiencies in the code that can be optimized.”
“Logback is a well-established logging library in the Java ecosystem. To configure Logback, it’s imperative to create a logback-spring.xml or logback.xml file in the src/main/resources directory. Spring Boot provides its own logging configuration options in the application.properties or application.yml file.”
“Developing and deploying a Java serverless function that invokes OpenAI API. Using Spring Cloud Function, Lambda Java 17 support and SnapStart turned on, let’s explore the details of developing a Java Lambda function. This function will be fronted by an HTTP API gateway.”
“Spring-IOC’s Dependency injection feature is the most commonly used feature and the most convenient feature for programmers to develop. After Spring Framework 4.0, Spring no longer recommends using field injection and instead recommends constructor injection and setter injection. There are three dependency injection ways in spring.”
“Custom libraries are the key solution for code duplication between microservices. DRY (Don’t Repeat Yourself) principle encourages us to create code that can be reused. Custom libraries pull duplicated code into abstractions such as a custom library that we can then call from multiple places.”
“Social login with Spring Boot 3.1 with Google OAuth2 Client. OAuth 2.0 flow typically involves several components, including Resource Owner, Client, Authorization Server and Resource Server. The user initiates login and clicks on the “Login with Google” button.”
“Zero Trust Security is a modern approach that treats every access attempt as potentially harmful. By integrating Zero Trust principles with Spring-based microservices, businesses can establish a security model that is both flexible and robust. The concept of “Zero Trust” might sound radical at first, but it’s a strategic response to the changing landscape of security threats.”
“Spring Boot + Cross-Site Request Forgery (CSRF) is a common web security vulnerability that allows attackers to make unauthorized actions on behalf of a user. In this blog post, we’ll walk you through implementing CSRF protection in a Spring Boot application with a practical Java code example.”
“Micronaut is an open-source initiative by the team behind Grails and Spring. It is designed specifically for microservices, tailored specifically for cloud-native microservices. It has Ahead of Time Compilation, which allows it to generate meta-information needed for the framework to operate during compile time rather than at runtime.”
“In microservices architecture, managing configurations can become a Herculean task as the number of services grows. Spring Cloud Config is a project within the larger Spring Cloud ecosystem designed specifically for centralized configuration management in microservices. It ensures that all microservices in the system can retrieve their configuration from a centralized source.”
“API Mocking is akin to a doppelganger in the world of APIs. It’s the process of creating a stand-in or a simulation of an actual API to emulate its behavior without relying on real backend operations. Spring Boot, a popular framework in the Java ecosystem, provides utilities that make mocking easy.”
“Developing applications that cater to a wide range of users from various geographical regions is no longer optional but necessary. Spring Microservices offers a solid foundation to manage these complexities. Managing and interpreting time data across various zones isn’t just a nicety — it’s a necessity.”
