MAVEN builds Spring boot project manually

1. Create a new, empty Maven project.

2, modify Pom.xml:

Add spring Boot's parent dependency (spring-boot-starter-parent), which is a special starter to provide the relevant MAVEN default dependencies-such a project is the Spring boot project. Default dependency, which is version default, some common dependencies can be removed <version> tags. As to which jar packages the spring boot is dependent on, and how much the version defaults to, see the \org\springframework\boot\spring-boot-dependencies\ directory in the local repository (if available locally) Spring-boot-dependencies.pom file.

Create a new entry class (Artifactid + Application naming convention) and declare the Ingress class directly as a simple controller as a test:
