Spring Boot source code interpretation and principle analysis

  Recently, by chance, I read the book "Spring Boot Source Code Interpretation and Principle Analysis" written by LinkedBear. I spent a lot of time I spent a week studying this book carefully, and it really benefited me a lot. I recommend it to everyone. It is a good book not to be missed.

1. About the author

LinkedBear is a senior Java development engineer who has been committed to the research of underlying technology all year round. He has also shared many excellent articles with everyone through the technical content community. He has devoted himself to studying the Spring technology system for many years and has unique insights into frameworks such as Spring, Spring Boot, MyBatis, etc., and has rich practical experience in framework systems and architecture encapsulation experience. I myself also learned a lot of useful knowledge from his sharing.

2. Positioning of this book

  This book mainly explains the working principle of Spring, and gradually dismantles the implementation mechanism of Spring by interpreting the source code. Therefore, the target readers of this bookRequires certain Java foundation and Spring experience. Based on my reading experience, I think readers need to have the following basic knowledge:

• Java basics
• Basic usage of Spring framework
• Have a preliminary understanding of Spring Boot
• Interested in reading the source code of the framework
• I hope I can fully master Spring Boot from the shallower to the deeper level.

3. Target readers

Based on my reading experience during this period, I think the following people are suitable for reading this book:

• Partners who have used Spring and Spring Boot in actual development, and are interested in exploring deep features and high-level usage; a>
• Technical enthusiasts who want to delve into the underlying logic of Spring and Spring Boot and learn its implementation principles and source code;
• Senior developers who intend to become technical directors or architects.

4. Feelings after reading

In order to allow readers to read this book step by step, the author has divided the content planning into the following four parts, explaining it from the shallower to the deeper.

• Part 1: The core container that Spring Boot relies on at the bottom level
  Mainly introducesSpring Bootthe underlying core container, andSpring's two core features: IOC and AOP;

• Part 2: Analysis of Spring Boot’s life cycle principles
  Starting from the source code, in-depth analysis of Spring’s life cycle, including< The life cycle of a i=3>, , and ;Spring ApplicationIOC容器嵌入式Web容器AOP模块

• Part 3: Common Development Scenarios for Spring Boot Integration
  Based on actual development scenarios, the core assembly and key mechanism principles of the integration of each module in project development are introduced in detail;

• Part 4: Running Spring Boot Application
  ExplainSpring Boot the application packaging method and startup boot process.

  After reading the whole book, my biggest feeling is that it moves from the shallower to the deeper and is guided step by step. During the explanation process, the author will break down the entire knowledge that needs to be explained into incremental steps through a vivid example in life, and finally give you a comprehensive understanding of the entire system. Just like building blocks, several groups of different components are built one by one, and then the components are spliced ​​into the finished product. It was through such step-by-step guidance that I fell in love with this book. During my reading process, I rarely experienced the boring feeling of reading other technical books.

  Take a chapter in the book as an example:

  When explaining the chapter Spring Framework module assembly, the author introduced the example of 酒馆 , naturally introduces four different entity elements: 吧台, 调酒师, 服务员, 老板 , combined with @Import the different values ​​that can be imported, vividly completed the module assembly explanation of the entire knowledge point; through < /span> and their respective usage scenarios. and cleverly explain the differences between 酒馆所处的不同环境 and 老板与吧台的内在关系基于Profile的装配基于Conditional的装配

  Another feeling I have is: Detailed .

  Under each chapter in the book, there will be a lot of tips, which are common mistakes and misunderstood knowledge points. This will be of great help to beginners. It was during the actual practice that I came up with this. It was the same mistake as in the book. Fortunately, I discovered the prompts in the book in time.

  Overall, the author focused on several core modules of Spring Framework and Spring Boot through structured splitting and analysis (IOC, AOP, transactions, Web, embedded containers, etc.), combined with vivid scenes and examples, strive to let readers put aside their fear of difficulties and learn more easily and comprehensively, while also achieving sufficient depth and the lowest possible level Understand the difficulty. The book uses detailed source code analysis and thoughtful tips to help beginners learn and understand, as shown in the figure below:

  In addition to the rich content and clear logic of the book, the author also provides high-quality, reproducible, and continuously updated open source code and hosts it on the GitHub platform. Students are welcome to check and study. The specific warehouse address is: https://github.com/LinkedBear/spring-boot-source-analysis-epubit.

5. Features of books

  The biggest features of this book arecomprehensive, detailed , it not only covers the source code of each core component of Spring Boot, but also explains it with specific cases; when it comes to the source code, the author specially cuts and comments the source code in detail, which is really friendly to readers. Compared with other general introductions to the Spring Boot source code, this book's analysis is more detailed and specific. For developers who have just started to come into contact with the source code, it is the best choice to understand the operation of the Spring Boot core.

6. Summary and outlook

  Generally speaking, LinkedBear's "Spring Boot Source Code Interpretation and Principle Analysis" is very detailed and combines a large amount of source code , tips and cases, which are very helpful for readers to understand the principles of the framework. It is a rare reference reading for researching and learning Spring Boot source code.

  I strongly recommend developers who are interested in Spring Boot source code to read this book. It will help you build the Spring Boot knowledge framework and learn the methodology of source code analysis.

  Spring Boot eliminates the need for developers to switch their thinking between configuration and logical business, and instead devotes themselves to writing code for logical business, greatly improving development efficiency and shortening the project cycle. As such an efficient Java framework, I believe that more people will use it to achieve great success in the workplace in 2023.
