Hello everyone, many friends have left messages in the background recently, and they have to prepare for an interview again, and I don't know where to start!
In the new year, we need to seize new opportunities, whether it is job-hopping, salary increase, or learning and improvement! Set yourself a small goal first, and then work hard towards the goal and you're done!
In order to help you save time, I have brought you a collection of 2022 Dachang Java interview questions.
Generally, technical interviewers will use their own methods to examine the technical skills and basic theoretical knowledge of programmers.
For example, questions like this:
Are you familiar with the implementation principles of the project framework, Spring, MyBatis and other frameworks?
Have you come into contact with technologies such as message middleware, load balancing, and RPC framework? Has MySQL sub-database and table been done?
Distributed architecture design, is Redis distributed lock involved?
...... (1W words omitted here)
In many cases, the questions asked by the interviewer will be different from the questions in the "question bank" prepared by myself. Even after doing a review, I still don't know where to start the next interview.
For this reason, I specially compiled a copy of "Java Advanced Learning + Interview Collection" to share with you. The content covers: computer foundation, Java, JVM, spring, algorithm, micro-service, distributed, big factory experience, technical brain map, etc. Wait...a total of 1700+ pages are of very high quality! ! !
Regardless of whether you want to go to an interview recently, it is recommended that everyone keep a copy! ! After finishing the study, whether it is promotion in the factory or job hopping and salary increase, it is no problem!
The content is as follows:

12. Practical project (Github explosion) 2023 edition
This project is a standard and launched "online car-hailing" application. It meets the technical requirements of the Ministry of Communications of my country for the supervision of online car-hailing. Passed the Ministry of Communications' online and offline capacity certification for online car-hailing. The prototype of the project was put into operation in Hangzhou.
The core functions of the project include: account system, order system, payment system, map engine, dispatch engine, message system and other core solutions for online car-hailing.
The project fully adopts micro-service architecture design, applies a mature interface security design scheme, uses distributed locks to ensure data synchronization in a distributed environment, and uses distributed transactions to solve data consistency in a distributed environment.
Prerequisite skills: Git, Maven, Spring Boot, Spring Cloud, Redis, MySql, RabbitMQ, ActiveMQ, etc.
