This article mainly explains "Java Spring Framework example Analysis". Interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Next, let the editor take you to learn "Java Spring Framework example Analysis"!

Seeing the code above, I have to mention the Spring framework. When developing Spring programs, many developers passively accept the cases of Spring features that have been done. Although this reduces development costs, it also limits its own ability to scale out.

The Spring framework integrates almost half of the Java Web development, so it is very dangerous to know how to write, but do not know why and how to optimize it.

As a lightweight Java development framework, Spring permeates the interface-oriented programming idea throughout the application of the Java system, so it has always been a high-frequency inspection point in the interview. The two major characteristics of Spring, IOC and AOP, are also knowledge points that must be mastered through the interview.

However, in the course of several interviews, I found a problem: many Java programmers do not fully understand IOC and AOP, but only IOC is control inversion and AOP is aspect-oriented.

With the life cycle of Bean as a breakthrough, the problem of circular dependency may arise in the process of dependency injection, and circular dependency is very complex. Do you know why Spring must use "three-tier cache" to solve circular dependencies when it is possible to use "two-tier cache"? What will happen if one of the levels of cache is removed? Is there a problem if a singleton bean and the prototype bean depend on each other? Will it be a problem for the two prototype bean to depend on each other?

So we found that there are still a lot of technologies and problems in Spring that we don't know about. If the understanding of a framework only stays at the level of proficiency in use, then someone else may replace you at any time.

At this point, I believe that you have a deeper understanding of the "Java Spring Framework example Analysis", you might as well come to the actual operation! Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
