foreword
On the occasion of "Golden September and Silver October", young graduates are full of hope and apprehension, looking for and competing for a job opportunity. The development students who are already working also want to get better treatment and a bigger platform through social recruitment or internal referral.
However, there are a lot of people interviewing, but the technology market is relatively cold, and the students who are interviewing have to face the huge competition of N applicants for one position.
Q: Under this current situation, how can we get more and better offers?
Answer: Short-term preparation - brushing up interview questions; long-term planning - consolidating core skills.
How to brush the interview questions? Use high-frequency questions, in-depth questions, and time-sensitive questions.
How to consolidate core skills? First understand the principle in depth, and then apply it systematically to practice.
Hey guys, have you used Spring and SpringBoot? Do you feel that Spring is really a powerful framework, and SpringBoot makes Spring even more awesome? I think everyone thinks so too! SpringBoot is quite popular in the current Java back-end development. Many companies and development teams choose SpringBoot as the foundation framework for quickly building projects. The reason is that you and I know that it is convenient and simple, and annotations and programmatic configuration All make us feel simpler, easier to understand and maintain. But old man, you will use Spring and SpringBoot, have you ever thought about such questions:
-
SpringBoot only needs to rely on the starter to integrate into a module. How does it do it?
-
SpringBoot only needs to write the startup class, and annotate it to pull up a web application. I didn't add Tomcat. How did it start? What is the relationship between SpringBoot and Spring? How does it use Spring? How does Spring achieve such high-level and awesome mechanisms such as IOC and AOP?
-
People say that the underlying design of Spring and SpringBoot is very good, where is it reflected?
As you can imagine from these questions, SpringBoot is used by many people, but not many people understand its principles to tell the truth, and even fewer people can go deep into the source code to explore the bottom layer. (Hey buddy, don't run, wait for me to finish...)
