Love it! Alibaba blew himself up "Notes on Java Core Architecture", too awesome

Preface

The 2020 autumn social recruitment is in the midst of hot recruitment. Many people are concerned that the technical knowledge is not broad enough or deep enough, and even some basic questions can only be answered vaguely. You said, this job-hopping is not a loneliness?

In fact, the fundamental reason is that they are not systematic enough to master their own technology stack. Judging from the current recruitment requirements, a solid foundation is a necessary technical point for programmers. In addition, you need to explore the breadth and depth of the technology stack to form your own technical route X-Mind.

Recently, after a friend revealed, Alibaba blew up a "Java Core Architecture Notes". The knowledge points recorded in it are very complete. After reading it, I realized that the gap is really more than a little bit!

This note stratifies programmers according to development experience. You can clearly know which technology stacks you should master at which stage. Below I will introduce the main knowledge points covered in this note. Due to space limitations, only part of it can be shown. The screenshot content, the complete content can be clicked here to get the way to receive it.

Java core architecture notes are roughly as follows

0~1 years:

• Java basics (basic syntax, object-oriented, inheritance, polymorphism, interfaces and abstract classes, exceptions, inner classes, collections, generics, reflection, I/O, etc.)
• Web programming (Servlet + MySQL database + commodity management system combat)
• SSM framework entry to proficient (Spring+SpringMVC+Mybatis+SSM commodity management system combat)
• SpringBoot (SpringBoot+SpringBoot commodity management system actual combat)

1~3 years:

• Advanced JVM (JVM memory area + JVM runtime memory + garbage collection and algorithm + JAVA four reference types + GC generational collection algorithm VS partition collection algorithm + GC garbage collector, etc.)
• Advanced Concurrent Programming (Underlying Implementation Principle of Concurrency Mechanism + Memory Model + Concurrent Programming Foundation + Lock + Concurrent Container and Framework + Atomic Operation + Concurrent Tool Class + Thread Pool + Actual Combat)
• Advanced MySQL (Mysq|Storage Engine Selection and Precautions + Interpretation of Mysq|'s Shared and Exclusive Locks + Partition + Transaction Isolation Level + Index + Sql Optimization)
• Data structure and algorithm (Java programmers must ask for interview)

3~5 years:

• Distributed messaging middleware (Zookpeer+Kafka+MQ+dubbo+SpringCloud, etc.)
• Database (master-slave replication + read-write separation + sub-database sub-table)
• Efficient storage (Redis+MongoDB)

Over 5 years:

• Distributed extension to microservices (SpringBoot+SpringCloudAlibaba+Docker)
• SSM framework source code interpretation (Spring advanced source code + Spring MVC source code + Mybatis source code)

At last

I want to ask you what was the original intention of choosing to be a programmer? Have you thought about this problem? High salary? Love?

Now that you have entered this industry, you should know that this industry depends on ability to feed, and there is no problem if you want to get a high salary. Please hone your skills and don't complain. Some people can grow through training, and some can grow through self-discipline and strong self-learning ability. If you don't account for both, how can you get a high salary?

Architects are the career goals of many programmers. A good architect does not worry about the so-called 35-year-old threshold. At that time, a large number of companies still dig him. Why many people want to enter Alibaba is nothing more than good welfare and high-quality network resources, which is very helpful to personal career development.

If you also want to be a good architect, then perhaps you need to read the above Java core architecture notes , hoping to be helpful to your career development.
