Is the SSM framework obsolete?
I am very responsible to tell you that the SSM framework is out of date. Now many systems are built on the basis of SSM. And more and more companies choose SSM framework for development projects, including first-tier manufacturers;
Some people say: Spring Boot is the mainstream framework in the enterprise?
Spring Boot is developed on the basis of the powerful Spring Empire ecology. Spring Boot was invented not to replace Spring, but to make it easier for people to use Spring. Therefore, without Spring's powerful functions and ecology, there will be no later Spring Boot hotness. The concept of Spring Boot's use of conventions is better than configuration. The use of Spring has been refactored to make Spring's subsequent development more vital.
Spring does not repeat the manufacturing of wheels. It just combines the relatively mature and practical service frameworks developed by various companies, and repackages them in the style of Spring Boot to shield the complex configuration and implementation principles, and finally develop The authors set aside a set of distributed system development kits that are easy to understand, easy to deploy and easy to maintain.
Spring Boot is a member of the Spring family, and its design purpose is to develop and run Spring applications as simple and fast as possible, simplifying configuration. It provides convenience for developers to quickly use Spring and related development frameworks, but it is not a framework for microservices, it just provides a good scaffolding for the use of microservice frameworks.
In summary, we can understand it like this: It is the use of Spring Boot that makes Spring easier to use and more vital; so is there any conflict between these two?
Judging from the current recruitment needs, SSM is still one of the necessary skills for Java developers, so how to get started with SSM framework better and faster? Don't panic, some time ago, I got a SSM advanced practical manual from a big guy in Ali. It was really good to read it and share it!
content
The SSM framework is integrated by the three open source frameworks of SpringMVC, Spring and Mybatis, so to understand the framework, you need to start with these three frameworks.
This manual is divided into three parts: split the SSM framework into a unique interpretation, based on the analysis of the core code of SSM, break through the bottleneck of Java Web R&D, choose the easy-to-understand version of Spring, Spring MVC and MyBatis framework, Analyzed the implementation of each of the modules, digs out common design patterns from the code, and provides methodology and good practices for readers to understand the art of scalable design of the Spring series framework;

to sum up
In the environment of “rocketing” for interviews and “screws” for work, many programmers are very proficient in using these frameworks, but they lack sufficient accumulation and understanding of the underlying principles and architecture design, knowing it, but not knowing why. . Facing the complicated inheritance relationship of class libraries, pure English source code and comments, many engineers encountered many obstacles when learning. I also read the Tomcat source code three times at the time, but it was difficult to clear the customs.
How to help programmers quickly read the framework source code, familiarize themselves with the design philosophy behind it, and master its implementation skills, so as to be able to talk in front of high-level interviewers, but also to use it flexibly in actual work, rather than once Once you muster up the courage, but retreat in the whirlpool of source code?
This book is divided into 3 parts to do an in-depth source code analysis of SSM. Each article first introduces the main advantages of its framework, functional positioning and module division in Internet development; then analyzes each module and gives the UML diagram of the core class library. At the same time, the key code is annotated and interpreted. Readers present the essence of the framework; finally, combine a practical case to review the best practices in enterprise production.
If you want to solve the pain points of source code reading, quickly understand SSM, and truly understand the profound things in a simple way in your work, you must study in depth in this manual;
