After reading the SpringBoot growth tutorial notes and the Ali architects, I was very addicted to it. The high-definition electronic version is too fragrant

Spring has had a glorious time. It keeps pace with the times and leads the trend of Java programming for at least 10 years. Now, with the birth of Spring Boot, we no longer have to be constrained by Spring's cumbersome configuration. Spring Boot is an excellent framework for current back-end development. It is particularly prominent in today's numerous technologies.

Now that SpringBoot has entered version 2.0, what we bring to you today is the actual combat of SpringBoot after SpringBoot2.0. From entry to actual project combat with microservice SpringBoot, this note is positioned at entry, advanced, and actual combat. Therefore, we will take care of beginners who have a certain programming experience and a certain understanding of programming, as well as relatively senior developers.

This note has a total of fifteen parts, including the last two actual projects:

1. Enter the Spring Boot world
2. Prepare the development environment
3. Use development tools
4. Spring Boo basics
5. Layered development of web applications
6. Responsive programming
7. Spring Boot advanced
8. Use ORM to operate SQL database
9. Interface architecture style-RESTul
10. Integrated security framework to achieve security authentication and authorization
11. Using Redis to achieve high concurrency in Spring Boot
12. Use RabbitMQ to realize data exchange between systems
13. Use NoSQL database to realize search engine
14. Develop an enterprise-level general back-end system
15. Realize an e-commerce mall similar to Jingdong

In order not to affect your reading experience, I put the free method of obtaining this note at the end of the article! ! !
