Creating a Spring Boot project in Maven

• First we will create a basic java project and then we will modify it into spring boot

Syntax :

mvn archetype:generate 
	-DgroupId={project-packaging}
	-DartifactId={project-name}
	-DarchetypeArtifactId={maven-template} 
	-DinteractiveMode=false

Example :

mvn archetype:generate \
	-DgroupId=com.heapwizard \
	-DartifactId=java-maven-demo \
	-DarchetypeArtifactId=maven-archetype-quickstart \
	-DinteractiveMode=false

Note: You need to execute it as a single line in terminal or by adding \

mvn archetype:generate -DgroupId=com.heapwizard -DartifactId=java-maven-demo -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false

• Navigate to the directory where you have to create a the project folder. (Project folder is created by maven itself)
• Run the below maven command

Syntax :

Example :

Note: You need to execute it as a single line in terminal

• Now import the project in eclipse.
  • File – Import – Existing Maven Project – Finish

Execute the default main class and test :

• Add Parent POM.xml of Spring boot for default pom.xml configuration in spring boot

	<!-- Default Spring Boot configuration from Parent pom.xml -->
	<parent>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-parent</artifactId>
		<version>2.4.0</version>
	</parent>

• Add Spring boot web dependency in pom.xml

<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-web</artifactId>
			<version>2.6.1</version><!--$NO-MVN-MAN-VER$ -->		</dependency>

• Note: resource folder might not be available by default in main folder, so create in manually and add it in Java Build path source folder (Add Folder Button)

• Modify Create App.java file to start spring boot

package com.heapwizard;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.condition.ConditionalOnProperty;
import org.springframework.boot.task.TaskSchedulerCustomizer;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.scheduling.annotation.EnableScheduling;

@SpringBootApplication
public class App {
	
	private static final Logger LOGGER = LoggerFactory.getLogger(App.class);
	
    public static void main(String[] args) {
    	
    	LOGGER.info("Starting spring boot application");
    	SpringApplication.run(App.class, args);
    }
}

• Create an application.properties inside resource folder

server.port=9090
