The knowledge system required for Java programmers to transition from elementary and intermediate to advanced levels is roughly as follows (take Ali's technical sequence rank as an example):
The first stage: high-quality coding capabilities
At this stage, we should focus on a transparent understanding of the technology stack, including the correct use of algorithms and data structures, the efficient use of relational databases, and the use of design patterns to improve software architecture. Through the form of project output, it lays the foundation for Java language features, object-oriented/design patterns, databases, algorithms and data structures.
Phase 2: Independent architectural capabilities
After completing the first stage, it has basically reached the level of P5-P6. Next, we need to focus on systematic architectural thinking, that is, to cultivate independent architectural capabilities.
At this stage, it is recommended to build a general e-commerce platform, SpringBoot + Vue, so that you basically have mainstream architecture ideas, understand the principles and applications of mainstream middleware, and the design and implementation capabilities of high-availability architecture.
The third stage: the ability of technical experts
At this last stage, we need to focus on the high-availability architecture, including microservice architecture theory and practice, high-availability architecture design ideas, and familiarity with the JVM/framework/middleware bottom layer.
