Speaking of this, you may have to ask: If my work does not involve much network programming, is it necessary for me to spend energy learning Netty? In fact, in the middle and senior 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 are the performance aspects of Netty? What is the inspiration for your usual project development?
-
What are the important components in Netty and how are they connected?
-
How are Netty's memory pools and object pools designed?
-
What impressive system tuning cases do you have for Netty?
These seem simple, but if you don't have a deep understanding of Netty, it is easy to "roll over" when answering. I have interviewed many job applicants. Although they all have some experience in using Netty, when they delve into the technical details and how to solve practical problems in the project , they will find that most of them just use it simply and do not have a deep understanding of Netty technology. principle. So how do we learn Netty technology? As a beginner, you will definitely have many questions or encounter some problems:
Therefore, many previous practices, problem solving, and methods of learning Netty have been compiled into this Netty core principle analysis and source code interpretation manual, which is shared with friends in need . I will take you with me based on my rich experience in open source project analysis. Read the Netty source code, hoping to help you master it.
Netty core principle analysis and source code actual combat interpretation manual catalog
Each knowledge point has a navigation bookmark page on the left, which is very convenient to read. Since there are many contents, let’s take a part of the picture here.
Analysis of Netty's core principles and actual source code 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 necessary encoding and decoding skills for network communication, which is the source code for the following Analytical and practical sessions lay the groundwork
Netty Advanced Skills: The third part explains the core of Netty. Through multi-angle interpretation and analysis of Netty's core source code, 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: Build a Netty-based message push system from 0 to 1, and explain the core points to help you master network programming skills 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 am learning, I will try to challenge myself first. I asked myself in my heart: "How would I design its architecture? " Then I went to learn related blogs, source code and other resources, thinking about why the author's design is completely different from my own? Where is the difference between the two designs?
Here is also a summary of a mind map of Netty's core knowledge points, and I hope that the above Netty notes can help friends in need! From the shallower to the deeper, it takes you to establish a complete Netty knowledge system, and consolidate your Netty basic knowledge, Netty advanced skills, and practical development experience.
