preface

To date, Spring is the most popular and widely launched product in the Java ecosystem and job market. With the development of technology, Spring has developed from the former IoC framework into Cloud Native infrastructure, deriving a large number of Spring technology stacks, such as Spring Boot, Spring Cloud and Spring Security. There is no doubt that Spring has become the de facto industry standard for Java backend development. Countless companies have chosen Spring as the basic development framework, and most Java backend programmers come into contact with Spring in their daily work. Therefore, how to use Spring well? It has become one of the required courses for Java programmers! Today, we want to share is ali interviewer threw out the Spring source note, this note on GitHub heat has been marked 81.6K, so we can see the importance of this note to peers, but also means that it does bring a great improvement to our technology!
