At this point, you may be asking: If my job doesn't involve much network programming, do I still need to invest in learning Netty? In fact, in the intermediate and advanced Java development interviews of major Internet companies (Ali, Tencent, Meituan, etc.), questions related to the core technical principles of Netty are often asked, such as:
- What is the high performance of Netty? What inspires you in your usual project development?
- What are the important components in Netty and how are they related?
- How are Netty's memory pools and object pools designed?
- What are your most impressive system tuning cases for Netty?
These seem simple, but if you don't know enough about Netty, it's easy to "roll over" when answering. I have interviewed many job seekers, although they all have some experience in using Netty, but when we delve into the technical details and how to solve the actual problems in the project , we will find that most of them just use it simply and do not have a deep grasp of Netty technology. principle. So how do we learn Netty technology? As a beginner, you are bound to have many questions or encounter some problems:
Therefore, many previous practices and methods of solving problems and learning Netty have been organized into this manual of Netty core principle analysis and source code interpretation, and shared with those in need . Based on their rich experience in open source project analysis, I will bring you together. Read the Netty source code, I hope to help you master it.

Each knowledge point has a left navigation bookmark page, which is very convenient to read. Due to the large amount of content, here are some screenshots.
Netty core principle analysis and source code actual interpretation manual content display
Basic knowledge of Netty: The first and second articles introduce the whole picture of Netty, understand the development status and technical architecture of Netty, and explain the principle and use of Netty's core components one by one, as well as the coding and decoding skills necessary for network communication. Analytical and practical sessions to lay the foundation
Advanced Netty Skills: The third part explains the core articles of Netty. Through multi-angle interpretation and analysis of the core source code of Netty, it helps you quickly and accurately understand the technical principles of Netty's high performance, and apply the design ideas in it.
Netty practical development experience: from 0 to 1 to create a Netty-based message push system, and explain the core points, help you master the skills of network programming, and deepen your understanding of Netty.

Summarize
Before learning the source code, you must first make yourself a skilled worker and master the basic theory. In fact, no matter what framework I'm learning, I try to challenge myself first. I asked myself in my mind: "How would I design its architecture? " Then I went to study related blogs, source code and other resources, and thought about why the author's design is completely different from my own? What is the difference between the two designs?
A mind map of Netty's core knowledge points is also summarized here, and I hope that the above Netty notes can help those in need! From the shallow to the deep, you will establish a complete Netty knowledge system, consolidate your Netty basic knowledge, advanced Netty skills, and practical development experience.
