foreword
Since its inception, the Spring framework has been favored by developers, and some people affectionately call it: Spring Family Bucket.
Undoubtedly, Spring has already become the industry standard for Java back-end development. Countless companies choose Spring as the basic development framework, and most Java back-end programmers will also come into contact with Spring in their daily work.
Many developers regard Spring as the best Java project in their minds, not one of them.
So this is the key point and also the difficult point. You must know it at work, and you must test it during the interview.
