This guide is tailored to equip readers with practical insights and real-world applications, ensuring they possess the skills to construct robust and scalable microservices architectures. Starting with the fundamentals of Spring Boot and exploring its main modules, readers study essential topics such as microservices architecture, configuration management, database interaction, and security measures. Through practical guidance and hands-on exercises, you will learn to document endpoints effectively, streamline development processes, and implement strategies for efficient application packaging. With its emphasis on real-world case studies and industry insights, this book is an indispensable resource for developers, architects, and IT professionals seeking to leverage microservices architecture effectively in their projects and organizations, empowering them to harness the full potential of Spring Boot for building modern, scalable applications.

This revised edition is your practical, hands-on guide to developing Java-based enterprise applications with big data or batches of data using the Spring LDAP and the Spring Data LDAP frameworks.

Use the popular Spring Data project for data access and persistence using various Java-based APIs such as JDBC, JPA, MongoDB, and more. This book shows how to easily incorporate data persistence and accessibility into your microservices, cloud-native applications, and monolithic enterprise applications. It also teaches you how to perform unit and performance testing of a component that accesses a database. And it walks you through an example of each type of SQL and NoSQL database covered. After reading this book, you’ll be able to create an application that interacts with one or multiple types of databases, and conduct unit and performance testing to analyze possible problems. Source code is available on GitHub.What You’ll LearnBecome familiar with the Spring Data project and its modules for data access and persistenceExplore various SQL and NoSQL persistencetypesUncover the persistence and domain models, and handle transaction management for SQLMigrate database changes and versioning for SQLDive into NoSQL persistence with Redis, MongoDB, Neo4j, and CassandraHandle reactive database programming and access with R2DBC and MongoDBConduct unit, integration, and performance testing, and moreWho This Book Is ForExperienced Java software application developers; programmers with experience using the Spring framework or the Spring Boot micro framework

Learn the latest version of Scala through simple, practical examples. This book introduces you to the Scala programming language, its object-oriented and functional programming characteristics, and then guides you through Scala constructs and libraries that allow you to assemble small components into high-performance, scalable systems. Beginning Scala 3 explores new Scala 3 language features such as Top-level declarations, Creator applications, Extension methods to add extra functionality to existing types, and Enums. You will also learn new ways to manipulate types via Union types, intersection, literal, and opaque type aliases. Additionally, you’ll see how Implicits are replaced by given and using clauses. After reading this book, you will understand why Scala is judiciously used for critical business applications by leading companies such as Twitter, LinkedIn, Foursquare, the Guardian, Morgan Stanley, Credit Suisse, UBS, and HSBC – and you will be able to use it in your own projects.
