Spring Boot project deployment demonstration, install springboot to quickly generate starter classes and yml plug-ins

1. Spring Boot project deployment demo (simulate local deployment)

Demo package this project:

1. Add the pom.xml plug-in of the project; add the spring-boot-maven-plugin plug-in explicitly in pom.xml, otherwise the jar manifest
   file cannot be generated , causing the typed jar to fail to run with the command:
   
   pom.xml:

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"

</project>

2. Use the maven command package to package:
   (The project does not need to be started)
   After that, there will be the following jar package in the target directory under the project: Then the local path of the jar above:
   Run:
   Then open cmd here (no administrator is required):
   Input:
   xx.jar above java -jar
   

The operation is successful, and then we can directly access the resources just deployed in the browser without starting the idea:
such as input: the
test is successful! ! !

Second, install springboot to quickly generate the starter class and yml plug-in

When applying the spring boot project; under normal circumstances, it is necessary to create the startup boot class Application.java and application.yml configuration files, and the content is the same; for convenience, you can install an IDEA plug-in JBLSpringBootAppGen and right-click on the project. Automatically generate startup boot class Application.java and application.yml configuration files.

After downloading, right-click on any maven project or src directory in IDEA and select JBLSpringBootAppGen.

After clicking OK, the following content will be found in the project:
