Engineering With Java: Digest #10
Curated and Hand Picked Java and Spring Blogs.
In this edition of the Engineering With Java newsletter, we have hand-picked some interesting, must-read Java and Spring articles that will make us better Java developers and empower us to build better software. Hope you will like the work. Consider sharing your love by liking and sharing your feedback in the comment section.
1. Spring AOP: Log Requests and Responses with Annotations
Spring Boot AOP is a programming paradigm that enables modularization and cross-cutting concerns in software development. It allows developers to encapsulate certain behaviors or functionalities and apply them across various parts of a program, promoting cleaner code organization. Aspects, which are modules encapsulating cross-cutting concerns, such as logging, security, and transaction management, enhance code modularity, readability, and maintainability by separating core business logic from auxiliary functionalities.
2. Automating Database Migrations in Java with Flyway
Database migrations are crucial in software development, especially in environments with continuous integration and delivery. Manually managing these changes can be error-prone and time-consuming. Flyway is an open-source tool designed to simplify database migrations by providing version control for the database.

3. Discover 5 Mind-Blowing Lombok Functions That Will Amaze You
Lombok is a Java library that offers a range of features that can transform the coding experience from tedious to terrific. These functions are like shortcuts in programming that help developers write Java code more easily. The @Delegate annotation simplifies delegation in Java classes by automatically forwarding method calls to another class, creating a cleaner and more organized codebase. The @Cleanup annotation handles resource cleanup, making code more readable and less error-prone.
4. Top Most Detected Issues in Java Projects
SonarLint telemetry has identified the top most raised issues in Java projects, revealing over 2.5 million issues over the past two years. These issues, despite being trivial, can significantly impact the software's security, performance, and maintenance. To avoid these issues, developers should remove commented-out code, track the uses of "TODO" tags, and avoid adding new TODO blocks.
5. Implementation Best Practices: Microservice API With Spring Boot
The author shares useful tips at the different layers such as controller, repository, etc. for implementing microservices with Spring Boot along with sample codes.

6. Leveraging Java's Fork/Join Framework for Efficient Parallel Programming
The Fork/Join framework is a popular programming language that provides robust support for parallel programming. It enables developers to write concurrent programs that leverage multicore processors effectively. The framework consists of key components, including the ForkJoinPool, which manages a pool of worker threads responsible for executing tasks.
7. Java and Text Mining — Techniques for Extracting Information
The vast amount of textual data available today is growing rapidly, making it crucial to extract meaningful information from it. Text mining, or text analytics, is the process of extracting high-quality information from text, using natural language processing (NLP) and analytical methods. Java is often used for developing text mining applications due to its strength, ease of use, and scalability.

8. Cucumber in Spring Framework
Cucumber is an open-source testing tool that supports Behavior-Driven Development (BDD) by facilitating the creation, execution, and automation of BDD-style tests. It works based on the Gherkin Domain Specific Language (DSL), which allows developers and testers to write complex tests while making them understandable even for non-technical users. Key concepts in Cucumber include the Gherkin-When-Then structure, feature, scenario, background, scenario outline, and examples.
9. Exploring the Power of the Functional Programming Paradigm
Functional programming is a distinct approach to building software by composing pure mathematical functions over immutable data. It has gained mainstream acceptance due to the need for massive concurrency enabled by multicore computing systems and high-performance declarative architectures.
10. Using the JdbcTemplate class in Spring with the Oracle Database and UCP
This blog post explores Spring's JdbcTemplate class, which simplifies JDBC and helps avoid common errors. JdbcTemplate encapsulates core JDBC operations, leaving application code to provide SQL and extract results.
