I always hear developers talking about this problem, I believe it is a pain point for many people:
As an ordinary developer, seeing other people either join Ali or become an executive. It is inevitable that there is some envy in my heart, and I am unwilling to be content with the status quo. I have a strong desire to make progress, but I don't know what kind of technology to choose for in-depth study.
This problem is mainly the development direction of the developer. In my opinion, there are generally 4 directions to solve this problem:
- Based on the product itself
Remember that the company recruits people to solve problems. Based on existing problems, everyone generally has a general solution in mind, and this solution is usually a combination of several technologies.
For example, when a single machine encounters a performance bottleneck and the cost of simply upgrading the hardware is too high, I usually choose distributed technology, and there are specific technologies such as zookeeper and dubbo under distributed.
All in all, targeted learning is much better than "more but not fine". Good steel is on the edge.
- Expansion of existing technology
If you are a developer, you must be using some kind of technology. So if you want to study in depth, the most effective way is to go deep into the existing technology, and expand the study to form your own technology stack.
For example, I am currently doing video encoding and decoding, which can be learned like ffmpeg, OpenH264, WebRTC, etc.
After a while, you will find that you can be your own.
- Market demand
Most people can't avoid vulgarity. If you want to make money and get better development, you can choose your own learning direction according to market demand.
For example, there are more demands for artificial intelligence and the prospects are good, so you can choose Python, TensorFlow, etc.
Whether you choose the most widely used Java, Python, which performs well in artificial intelligence, or other languages, you must think carefully, and once you make a decision, you will never look back easily.
- Hobby driven
If you have the technology you are interested in, just follow your interest, and interest is the best teacher.
No matter which direction or technology you ultimately choose, the most important thing is perseverance. Only continuous learning and practice can make you truly proficient in a certain technology.
I am here also to provide an advanced roadmap for programmers who want to raise their heights but don’t know how to choose their direction, mainly for Java developers with 1 to 5 years of work experience, from breadth to depth. It's fairly comprehensive. The technologies inside include Java's high concurrency, distributed, microservices, source code analysis, high performance and other technologies. These are also the more commonly used technologies by Internet companies, so let's take a closer look. (Pictures can be saved)
One: Common patterns and tools
Learn Java technology system, design patterns, popular frameworks and components
Common design patterns, Spring5 is necessary for coding, MyBatis is the latest framework essential for applications , and is an essential component for playing databases
Two: Engineering and Tools
If you want to do your job well, you must first sharpen your tools. Whether you are a novice or a senior developer, it is essential to play with the Java technology system and choose good tools to improve development efficiency and team collaboration efficiency:
Maven, project management Jenkins, continuous integration Sonar, code quality management Git, version management
Three: distributed architecture
High concurrency, high availability, massive data, and no knowledge of distributed architecture is definitely impossible:
Principles of Distributed Architecture Distributed Architecture Strategy Distributed Middleware Distributed Architecture Actual Combat
Four: microservice architecture
Businesses are becoming more and more complex and services are layered. Microservice architecture is the only way to upgrade the architecture. What are the Java technology systems and microservice-related technologies?
Microservice framework Spring Cloud Docker and virtualized microservice architecture
Five: performance optimization
Any ppt architect who breaks out of the details is a rogue, can plan upwards and solve first-line performance problems downwards. The Java technology system needs to understand:
Performance index system JVM tuning Web tuning DB tuning
Six: Low-level knowledge
From architecture design to application layer tuning, and then a deep understanding of the underlying principles, a solid basic Java skills can turn oneself into a sweeping monk:
Memory model concurrent mode thread model lock details
The above is a graph of Java architecture technology collected and summarized by myself. Because I prefer technology, I have collected some architecture technology materials such as Java high concurrency, distributed, JVM, spring, source code analysis, and kafka. If you are also interested in technology, trouble one Press three links + comment, then add VX (tkzl6666) to receive it for free
Share it with programmers who like Java, programming, and dreams of becoming architects. I hope to help you.
