A basic knowledge of the Spring Framework and Java is assumed. What You Will Learn • Develop applications using dependency injection patterns • Learn best practices to design enterprise applications • Explore Aspect-Oriented Programming relating to transactions, security, and caching. • Build web applications using traditional Spring MVC patterns • Learn to configure Spring using XML, annotations, and Java. • Implement caching to improve application performance. • Understand concurrency and handle multiple connections inside a web server. • Utilizing Reactive Programming Pattern to build Reactive web applications. In Detail Design patterns help speed up the development process by offering well tested and proven solutions to common problems. These patterns coupled with the Spring framework offer tremendous improvements in the development process. The book begins with an overview of Spring Framework 5.0 and design patterns. You will understand the Dependency Injection pattern, which is the main principle behind the decoupling process that Spring performs, thus making it easier to manage your code. You will learn how GoF patterns can be used in Application Design. You will then learn to use Proxy patterns in Aspect Oriented Programming and remoting. Moving on, you will understand the JDBC template patterns and their use in abstracting database access. Then, you will be introduced to MVC patterns to build Reactive web applications. Finally, you will move on to more advanced topics such as Reactive streams and Concurrency. At the end of this book, you will be well equipped to develop efficient enterprise applications using Spring 5 with common design patterns Style and approach The book takes a pragmatic approach, showing various design patterns and best-practice considerations, including the Reactive programming approach with the Spring 5 Framework and ways to solve common development and design problems for enterprise applications.

Learn and implement various techniques related to testing, monitoring and optimization for microservices architecture.Key FeaturesLearn different approaches for testing microservices to design and implement, robust and secure applicationsBecome more efficient while working with microservicesExplore Testing and Monitoring tools such as JMeter, Ready API,and AppDynamicsBook DescriptionMicroservices are the latest "right" way of developing web applications. Microservices architecture has been gaining momentum over the past few years, but once you've started down the microservices path, you need to test and optimize the services. This book focuses on exploring various testing, monitoring, and optimization techniques for microservices.The book starts with the evolution of software architecture style, from monolithic to virtualized, to microservices architecture. Then you will explore methods to deploy microservices and various implementation patterns. With the help of a real-world example, you will understand how external APIs help product developers to focus on core competencies. After that, you will learn testing techniques, such as Unit Testing, Integration Testing, Functional Testing, and Load Testing. Next, you will explore performance testing tools, such as JMeter, and Gatling. Then, we deep dive into monitoring techniques and learn performance benchmarking of the various architectural components. For this, you will explore monitoring tools such as Appdynamics, Dynatrace, AWS CloudWatch, and Nagios. Finally, you will learn to identify, address, and report various performance issues related to microservices.What you will learnUnderstand the architecture of microservices and how to build servicesEstablish how external APIs help to accelerate the development processUnderstand testing techniques, such as unit testing, integration testing, end-to-end testing, and UI/functional testingExplore various tools related to the performance testing, monitoring, and optimization of microservicesDesign strategies for performance testing Identify performance issues and fine-tune performanceWho this book is forThis book is for developers who are involved with microservices architecture to develop robust and secure applications. Basic knowledge of microservices is essential in order to get the most out of this book.

Let us full stack development with Spring Boot and React JS Key Features ● This book has a very specific goal to make developing REST applications easier and focusing on common challenges of the design of the application with best practices. ● This book is providing practical code examples from real-world experiences. ● This book is not only about Spring Boot 2.2 and React JS overview but also has an in-depth discussion about adopted REST Architectural pattern and its constraints to create the REST APIs. ● The book can act as a tool for learning Spring Boot 2.2 and React JS for the first time as well as a guide and reference for those wanting to dig deeper into specific features. ● This book is also providing deeper information about the Spring Security and JWT token-based authentication for your REST applications. ● Containerization using Docker is another key feature of this book, how to create a Docker image and how to run it. Description Designing Application with Spring Boot 2 & React JS is divided into three parts. The first part introduces you to the essentials of the Spring Boot 2.2 Framework and you will learn how to create REST APIs and how to secure REST APIs. Part 2 steps behind the front end application development with React JS and discuss React features and its advantages toward the frontend application development. Part 3 expands on that by showing how to deploy backend and frontend application the PaaS platform and also will discuss how to deploy application container technologies such as Docker. What will you learn ● Exploring Spring Boot 2.2 new features and essential key components such as Starters, Autoconfiguration, CLI, Actuator. ● Develop a REST application using Spring Boot 2.2 and DevTools. ● Exploring Spring Boot Auto Configuration and Customization. ● Creating application profiles based on the environments. ● Learn to configure backend data using JDBC and Spring Data JPA. ● Learn to configure a DataSource for H2 DB, and also for Maria DB. ● Learn best practices for designing a REST architecture based application. ● Creating a REST application using HATEOAS. ● Consuming REST APIs endpoints with RestTemplate, Traverson, and WebClient. ● Exploring JWT web token for the RESTful APIs and explores how to secure REST APIs using OAuth2 and Spring security. ● Creating TESTING module of the Spring Boot application and Unit & Integration testing. ● Discuss React JS and its components and also discuss React KS features and its advantages and disadvantage. ● Exploring how to create ReactJS components and how to manage ReactJS component lifecycle. ● Taking a quick overview of consuming the REST API using the React application. ● Deploying the application to the Cloud platform (PaaS). ● Containerization and Deploy using Docker containers Who This Book Is For For all Java developers who want to learn Spring Boot 2.2 and React JS as in the enterprise application.
