Looking back, I have been doing development for ten years. In the past ten years, I have gained a lot of technical skills, training, experience in going abroad, large companies, and many good friends. But think about it again, I wasted at least five years in these ten years. These five years are enough to make myself grow into an excellent programmer. Unfortunately, I missed it. I spent these five years in the same way as many programmers. There is no way out in the confusion and confusion!
The road has always been there, we just can't see it!
In the past, I was always led by companies and technologies. It was not that I was choosing the technology myself, but that I was pushed to this position unconsciously. Think about how many people have thought deeply and compared the type of career and technology they want to pursue in the future? After I jumped out of coding, I began to think about programming and programmers' careers, and finally found that it was some of the words we often talked about that led us into today's predicament.
SpringBoot is adopted by more and more microservice practitioners for its lightweight, embedded web container, one-click startup, and convenient debugging. However, if you know the truth, you must know the reason. This Chat will explain the implementation principle of the SpringBoot core module, which is often asked during the interview. The core content mainly includes:
- spring-boot-load module, under normal circumstances a class loader can only find the current directory in the jar package of the loading path or the *.class file in the file class, SpringBoot allows us to use java -jar archive.jar to run including nested dependencies jar or war file of jar, so how does SpringBoot implement it?
- The spring-boot-autoconfigure module, the emergence of Spring provides us with convenience for managing bean dependency injection, but when we need to use a bean in the jar introduced by pom, we still need to manually configure it in the XML configuration file. Springboot can automatically configure beans to the Spring container according to the dependencies in the classpath.
- The spring-boot module provides some features to support other modules in SpringBoot. This article will explain what functions and principles this module provides.
So is there no correct way to learn SpringBoot? Here, the editor will share with you a fairy-level SpringBoot core note, with pictures and texts, which is very suitable for friends who need to learn SpringBoot!
