Summarized a skill tree of a Java architect. I hope it will be helpful to the students of Java programming. At the end of the article, there is a way to obtain the skill tree of the architect.
Java programming technology points:

Classic design pattern
Database: NoSQL such as MySQL and MogoDB
Distributed architecture
Involved: distributed redis, distributed session, microservices: dubbo, spring cloud, docker, etc.
In addition, algorithms and data structures, Java concurrent programming, etc. are also involved, all in this map.
Note: The following is mainly my personal summary method experience (interview study and brushing notes), all have a PDF full version
01 Sort out the knowledge system, learn to check for omissions
Regarding the combing of the knowledge system, I personally mainly divide it into the following 5 parts, which are targeted. If these 5 parts are gradually broken, then there is basically no problem in getting the interview.
- Concurrent programming: multithreading, high concurrency, CAS, lock, container, thread pool bottom layer
- Performance tuning: Mysql, IO and network tuning, algorithm tuning, JVM
- Spring family bucket: Spring, SpringMVC, MyBatis, IOC, AOP
- Cache database: Redis, mongoDB, MySQL
- Distributed & microservices: SpringBoot, SpringCloud, docker, maven

02 Break down one by one according to the main points (review according to the outline content)
1. Concurrent programming (core technical notes)
- Java multithreading skills
- Concurrent access to objects and variables
- Inter-thread communication
- Use of Lock
- Timer
- Singleton mode and multithreading
- Supplement
2. Performance tuning (Java performance tuning + MySQL tuning + JVM tuning)
3. Spring family bucket (Spring family bucket learning brain map + SpringBoot usage notes + deep analysis of source code)
- Spring learning mind map (Xmind)
- Spring usage notes + actual documentation
4. Cache database (MySQL+Redis+mongoDB)
03 Finally, look at the interview questions to draw inferences from one another (swipe the questions and brush the questions, and tell the important things three times)
There are also methods for interviewing questions. It is best to follow the topic, and then from basic to advanced, from shallow to deep, the effect will be better. Of course, I also organize all these contents in a pdf document,

Divided into the following major topics:
- Java basic part
- Algorithm and programming
- Database part
- Popular frameworks and new technologies (Spring+SpringCloud+SpringCloudAlibaba)
This interview document is of course more than these contents. In fact, other parts of the interview content such as JVM, design patterns, ZK, MQ, data structures, etc. are involved. Because of the length of the article, not all of them are explained here.
Write at the end
As a programmer, phased learning is indispensable, and it needs to maintain a certain degree of continuity. This time, during this phase, I conducted a systematic review of some key knowledge points, which on the one hand consolidated my own The foundation, on the other hand, has also improved the breadth and depth of their knowledge.
Finally, a reminder, if you want to learn but have no choice but to have no dry goods learning materials, all the above materials can be shared with you for free, as long as you support it.
