Spring has a glorious time, it keeps pace with the times and leads the trend of Java programming for at least 10 years. Now, with the birth of Spring Boot, we no longer have to be constrained by Spring's cumbersome configuration. Spring Boot is an excellent framework for current back-end development. It is particularly prominent in today's numerous technologies.
This document is written in the form of " knowledge points + examples" for Spring Boot 2.0 and above . Through "58 knowledge-based examples + 2 comprehensive projects" , this book explains in depth the technical principles, knowledge points and specific applications of Spring Boot; it presents the obscure theoretical examples and makes readers more knowledgeable. It becomes very easy to understand, and at the same time learn how to use it immediately.
To become a book with "temperature" , it is not enough to just do the above. Therefore, this book spends a lot of space to compare and explain the knowledge points, usage and differences of a variety of similar technologies. Readers can choose the technology according to their own preferences; it also explains the popular interface architecture style RESTful and is used to achieve high concurrency. RabbitMQ, the middleware for communication between Redis and the system. The last two chapters integrate the knowledge points of this book, and explain two common and practical practical projects.
This document is suitable for all readers who are interested in Spring Boot.

The first introduction
Chapter 1 Entering the Spring Boot World
Chapter 1: In addition to the relationship between Sping, Spring Boot and Spring Cloud, the author also focuses on how to use development tools (such as IDEA) to achieve development, how to find class object methods through API documentation, and tell us about the development process How to learn, discover and solve problems in Chinese, which has never been seen in many books, is also the author's carefulness.
Chapter 2 Preparing the Development Environment
Chapter 3 Using Development Tools
Chapters 2 and 3: The author talked about the establishment of the Java environment and the use of development tools. Especially in Chapter 3, it describes the use of various development tools (IDEA, Eclipse, STS) and the installation method of plug-ins in great detail. For beginners, Chapter 3 is worthy of careful experience and can be used as a tutorial for introductory development tools. The usage of the tools is also practiced by the author. In addition, the author also described how to use IDEA shortcut keys, readers can follow the steps demonstrated in the book for actual operations. If a worker wants to do his job well, he must first sharpen his tools. So I hope readers will not ignore the content of this chapter.

The second basic article
Chapter 4 Spring Boot Basics
Chapter 5 Layered Development of Web Applications
Chapter 6 Reactive carbuncle
Chapters 4~6: These 3 chapters are the basics of this book, especially for beginners. Chapter 4 describes the construction of SpringBoot projects, how to use Spring Boot annotations for development, and explains the basic concepts and usage principles of annotations. At the same time, readers can follow the examples for actual operations and experience the combined use of annotation programming and configuration files. Chapter 5 describes the MVC mode and principle of Spring Boot in detail, and at the same time explains the Thymeleaf template engine through examples, so readers can easily get started. Chapter 6 allows readers to deeply understand the development process of reactive programming WebFlux and how to connect and operate MongoDB databases. Readers can follow the examples to practice. The ancients said: Folding leaves and Gaojie, both born from the last. Therefore, I hope that readers can get a solid foundation through the study of Chapters 4~6.

The third advanced chapter
Chapter 7~13: In the theoretical explanation part, let us understand the technical key points needed in the work, and then use examples to let us learn in depth, improve the technical level, easily meet the work, and truly apply the knowledge points and practical skills to the work in. ;
Chapter 7 Spring Eoot Advanced
Chapter 7 analyzes two important features of Spring: AOP and loC;
Chapter 8 Operating SQI Database with DEM
Chapter 8 describes how to use ORM and its principles;
Chapter 9 Interface Architecture Style-RESTful
Chapter 9 describes the request method of the interface, and the definition of the standard style of the interface
Chapter 10 Integrated security framework to achieve security authentication and authorization
Chapter 10 explains Spring Security;
Chapter 11 Integrating Redis to achieve high concurrency
Chapter 11 explains Redis and its working principle and use;
Chapter 12 Integrate RabbitMQ to achieve data exchange between systems
Chapter 12 explains RabbitMQ, a messaging middleware that has been widely used in recent years;
Chapter 13 Integrating NoSQL Database to Realize Search Engine
Chapter 13 explains how to use NoSQL databases to achieve the effects of the two major search frameworks, Elasticsearch and Solr. At the same time, it explains the search engine in detail, and implements data addition, deletion, modification, and query operations through examples. The author tells us his many years of work experience and the knowledge that must be mastered in his work through a combination of theory and practice, so that we can grow from a technical "rookie" to a technical "master" in a short time.
In view of the importance of Chapters 7 to 13, I hope that readers will read it a few times. Therefore, I hope that readers can improve the breadth and depth of knowledge through the study of Chapters 7 to 13.

The fourth project actual combat
Chapters 14 and 15: The author carefully prepared two project examples. The knowledge of these two chapters is also a question that interviewers often ask when we are looking for a job. For example, how many projects have you done? What kind of technology? So, through these two chapters, you can understand the actual projects and integrate the previous content. It's always shallow on paper, and I absolutely know that I have to do it myself. I hope readers can do it themselves.
