Recently, many friends have asked me that my kids at home are going to work, or their work has not improved much. They are all programmers. The gap is so big. Think about it, it has been 10 years since outsourcing. , Looking back on the 10 years of my work, the summary is:
Get out of your comfort zone and keep learning deliberately to become an architect.
Nowadays, the speed of technology development is very fast, where should you start your deliberate practice next? 5 tips for you:
1. Understand the framework source code
The framework itself is a tool, but as a senior engineer and architect this is something you must learn and master. Letting you read the source code does not really make you understand it, but to understand the principles of its underlying implementation, and cultivate the framework thinking and the ability to customize the framework .
2. Master the distributed architecture design
Faced with the high concurrency, high availability, and high performance of Internet projects, you must master the architectural capabilities of distributed systems . In the face of billion-level data system architecture, how to meet the challenge of high concurrent traffic is a question that must be considered as an architect.
3. Deeply understand algorithms and underlying principles of computers
Part of the project performance bottleneck is achieved through low-level tuning, and some advanced kernel and engine development often require some sophisticated algorithms and an understanding of the underlying principles . Only by mastering these can we optimize the project from more perspectives.
And, if you go to some big factories for interviews, 100% of them will be met . Even if you do not use algorithms and underlying principles for your current work, you still have to learn as soon as possible how to enter a big factory like BAT in the future.
4. Master database tuning and selection The
most difficult part of the architecture is storage. How to use MySQL to support massive amounts of data and maintain high responsiveness, and how to keep the database running stably , are all skills that must be mastered. Whether it is the current mainstream MySQL, MongoDB, or HBase in the big data Hadoop ecosystem, etc.
Mastering these data technologies will allow you to be the icing on the cake, whether it is an interview or technical plan selection, and to be able to cope with the business needs extended to big data.
5. Performance tuning and solutions
In-depth use of mainstream application servers such as Tomcat and Nginx can be used to support business concurrency through performance tuning . Provide solutions to some classic scenario-based problems, such as SSO, instant messaging, order system, log system, etc., and know how to choose when faced with many solutions.
"About how to learn?"
During this period, I also brought some newcomers who have recently worked. Their common problem is that they are so busy at work and have no time to study.
This is indeed the case. The pace of the Internet is too fast. Sometimes I get off work late and I just want to rest when I get home.
I personally recommend that you make good use of the 2 hours after work, and 2 hours of study a day will not move. In a few years, your ability and salary will definitely be greatly improved.
Mainly include several aspects: learning + practice
In fact, this is also aimed at the shortcomings of the computer industry: learning is fast, but forgetting faster, if there is no hands-on operation, so I have also compiled some learning documents and 7 project practices for everyone
Look
1. Open source framework
Framework-related technologies such as Mybatis, Spring, and SpringMVC
2. JVM tuning
3. Mysql+concurrent programming+Netty+Linux+Tomcat
4. High concurrency and high performance
- MongoDB
- Redis
- Zookeeper
- Nginx
- Message middleware, etc.
5. Microservice series
Xiaotian won't talk about other technologies. If Java programmers can put the above technologies into the bag, it is not so important to you.
All in all, technical ability is the stepping stone to high salaries.
At last
I have compiled the PDFs of all the above core technical knowledge here, and also collected a set of the latest interview materials from major factories, as well as system interview questions. Friends who need help forward the article, backstage private message [Interview] to receive it for free!
If you need these information, scan the code below to get
After you have the knowledge points, the following is the actual combat of the project. Here is a summary of 7 projects. The above documents and the following projects are needed. After following + forwarding, you can view the acquisition method by privately mailing "data"
SmartAdmin
We open source a set of beautiful code and a set of neat code specifications, so that everyone in this impetuous code world feels a clear stream of well-written code! At the same time, it allows developers to save a lot of time, reduce overtime, work happily, and love life. SmartAdmin makes you realize that you can't forget it, it is definitely what you want most!
litemall
There is a small shopping mall system, Spring Boot backend + Vue administrator frontend + WeChat applet user frontend + Vue user mobile terminal.
Timo
TIMO background management system, a background management system based on SpringBoot2.0 + Spring Data Jpa + Thymeleaf + Shiro, adopts a sub-module method to facilitate development and maintenance, supports separate deployment of front and back modules, currently supported functions include: authority management, department Management, dictionary management, log recording, file upload, code generation, etc. Scaffolding for the rapid development of back-end systems!
Technical selection
- Rear end technology: SpringBoot + Spring Data Jpa + Thymeleaf + Shiro + Jwt + EhCache
- Front-end technology: Layui + Jquery + zTree + Font-awesome
mall4j
A lightweight based on spring boot, spring oauth2.0, mybatis, redis, separation of front and back ends, prevention of xss attacks, distributed locks, fully prepared for multiple instances in the production environment, the database is designed for b2b2c, with complete sku and order placement Fully open source mall of the process.
The project is committed to creating a complete and easy-to-maintain open source e-commerce system for small and medium-sized enterprises, which is implemented using current popular technologies. The back-end management system includes modules such as commodity management, order management, freight template, specification management, membership management, operation management, content management, statistical reports, authority management, settings, etc.
web-flash
Based on Spring Boot+Vue background management system, authority management, dictionary, configuration, timing tasks, SMS, email, export according to excel template, cms content management, mobile terminal h5, IDEA code generation plug-in.
SPTools
A back-end management system based on SpringBoot, JPA, and Shiro, with a single architecture, less dependency, easy to use, and benefits of back-end development. The most important thing is that it also comes with a free applet and microservice version , you can choose by yourself.
Built-in function
- Organizational structure: organization management, user management, role management, administrative area.
- System monitoring: system logs, online users, and will be added and improved later.
- Application management: task scheduling, email management, picture management, article management, check-in tasks, data query, artificial intelligence, each module only needs you to modify a little to create a project.
- System management: agile development, system menu, global configuration, online code editor, friends only need to design the table structure, three seconds to create a module for adding, deleting, checking and modifying.
summary
In fact, no matter what it is, documents, videos, projects, all these are just to be able to learn more solidly and to find a job with a satisfactory salary, but it is more of your persistence on the road of learning
