Springboot source code how to analyze the project structure, in view of this problem, this article introduces the corresponding analysis and solutions in detail, hoping to help more partners who want to solve this problem to find a more simple and easy way.

Summary of project structure for Springboot source code analysis:

Whether we extract it from IDEA or other SDS development tools or https://start.spring.io/, we will get the same pom.xml file 4.0.0 org.springframework.boot spring-boot-starter-parent 2.1.6.RELEASE.

Com.github.dqqzj springboot 0.0.1-SNAPSHOT springboot jar Demo project for Spring Boot 1.8 org.springframework.boot spring-boot-starter org.springframework.boot spring-boot-starter-test test Org.springframework.boot spring-boot-maven-plugin

Org.springframework.boot spring-boot-dependencies 2.1.6.RELEASE. /.. / spring-boot-dependencies ```indicates that our project can be modified to replace the original project `parent` tag.-org.springframework.boot spring-boot-maven-plugin Repackage repackage ${start-class} `repackage` is required, otherwise it will not start properly when you hit the jar package. ! [file] (https://cache.yisu.com/upload/information/20210524/347/779545.jpg) can org.springframework.boot spring-boot-maven-plugin by adding `repackage` to the configuration file Repackage `IDEA` comes with the `maven` tool! [file] (the https://cache.yisu.com/upload/information/20210524/347/779546.jpg)`mvnw` script command `mvnw.cmd` is based on `linux`. The script command `.mvn` contains the download path and version of `maven`, which means that instead of downloading `maven` by ourselves, we can directly use the tools provided to us by `IDEA`. It's just not usually done. # the role of `repackage`-[official documentation] (under normal https://docs.spring.io/spring-boot/docs/current/maven-plugin/repackage-mojo.html)- packaging, two files such as `repackage` and `original,springboot-0.0.1- SNAPSHOT.jar` will be generated The function of `repackage` is to repackage `springboot-0.0.1- SNAPSHOT.jar.pragal` into the `SNAPSHOT.jar` that we can execute. This is the answer to the question about how the Springboot source code analyzes the project structure. I hope the above content can be of some help to everyone.
