The content of this article is divided into six parts. If the article is longer, it is recommended to collect and study by comparison:
-
The first stage: essential skills for architects
-
The second stage: design pattern + open source framework interpretation
-
The third stage: Architecture technology performance improvement?
-
The fourth stage: efficient storage allows the project to take off
-
Phase 5: Distributed extension to microservice architecture
-
The sixth stage: exclusive face-to-face summary, super exciting

The first stage: essential skills for architects
I think that every adult should know how important a solid basic skills are to help their work. Judging from the recruitment requirements of major recruitment websites, the first one clearly states that a solid Java foundation is required. Therefore, in the first round of general written examinations and interviews, there are more basic investigations.
In fact, I found that there have been many developments for several years, and the basic knowledge is not solid. For example, briefly introduce what new features of Java 8 or what are the new features that you are good at? Either the answer is incomplete, or the answer is wrong.
Supporting learning documents
Big manufacturers must ask concurrent programming:
JVM in-depth disassembly:
Network programming and efficient IO:
Advanced MySQL:
Interview must ask about data structure and algorithm:
This note contains a lot of knowledge, it should be a necessary note, you can read it from time to time to check for omissions.
The second stage: design pattern + open source framework interpretation
The design pattern is the experience gained by the predecessors with their life's hard work and professionalism. The processing and streamlining of these experiences becomes the design pattern, that is, the routine. Once you have a routine, you can just put the type of business on it, it will not cause too much problem, and it is also conducive to the speed and scalability of software development.
At present, the mainstream open source framework of enterprises is the SSM framework, and the use of the SSM framework has long become a professional basis for Java development.
Supporting learning documents
Java design patterns:
SSM framework source code interpretation:
① Interpretation of Spring source code
②Spirng MVC
③MyBatis
The third stage: architecture technical performance improvement
Middleware is to solve a certain type of complex technical problems, such as message middleware Kafka, RocketMQ, which solves the queuing and buffering of a large number of processing requests, and achieves high performance without losing messages. This kind of general complex technology is common . TDDL, ShardingSphere, MyCat, etc. solve the problem of sub-database, sub-table, separation of reading and writing, and thus improve the problem of larger-scale data reading and writing for the entire system.
Recommended learning documents
Zookeeper：
NGINX：
RabbitMQ：
RocketMQ：
Kafka：
ELK：
The fourth stage: efficient storage allows the project to take off
Key knowledge points: Redis, MongoDB, MySQL high availability, Mycat
Nowadays, Redis and MySQL are popular in enterprises for storage. If there is not enough time, it is ok to understand these two.
Redis database:
MySQL database is highly available:
Phase 5: Distributed extension to microservice architecture
This stage belongs to the uplifting part. If you don't have enough time and you are anxious to find a job, you can skip this part and move on to the next stage, direct project learning, and make up later.
Docker：
ZooKeeper distributed coordination service technology + Dubbo high-performance RPC service publishing and calling framework:
Spring Boot：
Spring Cloud：
Spring Cloud Alibaba：
The sixth stage: exclusive face-to-face summary, super exciting
My interview experience summarized by companies such as Tencent, Ali, Baidu, etc., are all real, and I will share with you!
The seventh stage: Java interview preparation
To be precise, it is divided into two parts:
-
Java problem
-
Algorithm brushing
Java Questions: This document records thousands of interview questions and detailed explanations in detail;
Algorithm brushing:
It is normal for you to struggle with algorithmic questions at the beginning, so don't doubt your IQ. Zhihu often sees such questions: "Do you doubt your IQ when you first brush Leecode?" "Is it normal to brush Leetcode?" "What should I do if I forget Leecode"... These are all normal, except for geniuses. Except for the extremely smart people, all of us are the same. We will forget and forget, and we will not be able to do it and we need to see the answer. . .
It is recommended to study the algorithm advanced guide summarized by Alibaba's internal staff. The author carefully splits the common core algorithm questions and summary questions into two parts. For those eager to interview, you only need to read the common core algorithm questions in the second part of the algorithm topic. 150 pages in this section.
For students who have time, the author also gave out his ideas and methods for solving more than a thousand questions selected by combining many data structure algorithm books for students in need to study slowly.
Covers common written test interview algorithms and problem-solving ideas for all types of algorithmic questions. The layout of the entire book is very beautiful, each topic gives the idea of solving the problem first, and then the source code, and if necessary, the logic of solving the problem will be shown with illustrations. And all the authors of the topic also gave the source code, which the reader can run directly.
