Having said that, you may have to ask: If my work does not involve much network programming, is it necessary for me to spend my energy to learn Netty? In fact, in the intermediate and high-level 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 high performance of Netty? What is the inspiration for your usual project development?
- What are the important components in Netty and what are the connections between them?
- How is Netty's memory pool and object pool designed?
- What are your most impressive system tuning cases for Netty?
These seem simple, but if you don't have a deep grasp of Netty , it is easy to "overturn" when answering. I have interviewed many job seekers. Although they all have some experience in using Netty, when I delve into the technical details and how to solve the actual problems in the project , I will find that most people 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 must have many questions or encounter some problems:
So a lot of practice and solve problems before and that the learning Netty organized into a core principle of this Netty source code analysis and interpretation of the manual there is a need to come to share a small partner , based on their wealth of experience with open source projects analyze with you Reading the Netty source code, I hope to help you understand.

to sum up
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 learn, 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, and thought about why the author's design was completely different from my own. What is the difference between the two designs?
Here is also a summary of the mind map of Netty's core knowledge points, and I hope that the above Netty notes can help those in need! From the shallower to the deeper, you will establish a complete Netty knowledge system, consolidate your Netty basic knowledge, advanced Netty skills, and actual development experience.
