For development, we generally use various open source frameworks in our work, such as the most basic Spring, the Netty framework that makes the development of network programming particularly simple, and the Spring Cloud that has become the current preferred microservice framework. On top of multiple frameworks, we only need to use a few lines of code to achieve the complex functions required by the business, greatly reducing the workload.
Because of this, many people only use frameworks, do not understand the source code, and do not understand the underlying mechanism and implementation principles. They have become a developer who only handles source code libraries. To put it bluntly, the truly awesome technology does not belong to you.
You can understand a lot of knowledge and codes in the framework, which is extremely helpful to solve similar problems in development. Because they are time-tested and optimized, such as: MyBatis's architecture design, Dubbo's service discovery mechanism, Spring's design patterns, etc. Therefore, learning of source code and open source libraries has become the only way for Java developers to improve their skills.
I want to show you a picture of "Open Source Framework Learning Knowledge Graph", which contains four open source frameworks that Java engineers must spend time to learn-MyBatis, Spring, Spring MVC, Spring Boot, and a clear understanding of the knowledge needed to learn each framework Click here for the learning materials in the article: Quick download channel for learning materials!
I have sorted out the detailed knowledge points, and then based on my own actual experience + understanding of the framework source code, I will organize a detailed information for you, including hand-drawn illustrations, code comments, video materials, etc., and hope to help you find missing parts. Get to the bottom of the framework quickly.
One, MyBatis framework
MyBatis is an excellent persistence layer ORM framework, which encapsulates the process of jdbc operation of the database, so that developers only need to pay attention to the SQL itself, instead of spending energy to deal with such as registering the driver, creating a connection, creating a statement, manually setting parameters , Result set retrieval and other jdbc complicated process codes.
How to learn the MyBatis source code?
In the information I shared, the content is very comprehensive. It not only has an in-depth source code analysis for MyBatis, but also takes you step by step to implement a custom persistence layer framework.
MyBatis is also a common question in interviews. In addition to the source code, you must have an understanding of related concepts, caching, architecture principles, and plug-ins. Therefore, there is also a complete set of MyBatis learning materials in this material.
Second, the Spring framework
There is no doubt that Spring has become the basic development framework for countless companies, but most Java engineers will have various problems in the process of using them, such as: looking at so many components and wondering how to start? How does Spring solve the circular dependency problem? How to combine Spring with other frameworks?
This set of learning materials starts with the big framework, introduces you to the core structure of Spring, and then starts with the two core ideas of Ioc and AOP, and takes you step by step to understand what problems these two containers solve.
What's more exciting is that a lot of space is used later to analyze the basics, advanced features, and in-depth analysis of the source code of Spring IoC and Spring AOP, which is very worth seeing.
Spring framework learning knowledge points
Three, Spring MVC framework
The Spring MVC framework is still ahead of the competition. Over time, it has expanded into a complete MVC framework, and has evolved into a comprehensive Java framework. The framework is known for its well-developed ecosystem, and it provides many additional options, from REST API to secure encryption and authorization.
The following are the learning points of Spring MVC framework. According to this learning, proficiency in Spring MVC is not a problem.
Four, Spring Boot framework
Spring Boot improves and optimizes the shortcomings of Spring. Based on the idea that conventions are better than configuration, we don't have to switch thinking between configuration and logical business, greatly improving the research and development effect, and shortening the project cycle to a certain extent.
Mastering Spring Boot allows us to devote ourselves to the code programming of logic business.
If you are a middle or senior developer with 1-5 years of actual development experience, you usually use the framework to deal with daily development, but do not have a deep grasp of the underlying and large-scale architectures, then it can help you build the underlying capabilities in more depth.
