How to run integration test of a spring-boot based application through maven-failsafe-plugin?

I have a spring-boot based application, and the pom.xml file is configured as below.

                </executions>
            </plugin>
        </plugins>
    </build>


</project>

The main method located in class DemoApplication as below

package com.example.demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class DemoApplication {

    public static void main(String[] args) {
        System.out.println("This is a demo application+++++++++++++++++++");
        SpringApplication.run(DemoApplication.class, args);
    }
}

And my integration test class called DemoIT as following.

package com.example.demo;

import org.junit.Test;

public class DemoIT {

    @Test
    public void test() {
        System.out.println("This is a integration test.==============");
    }
}

Now here is my question, when I issue mvn clean verify command, the integration class DemoIT is supposed to be executed, and it does. However, my DemoApplication isn’t running. So I’m wondering if my integration test needs to be executed under the spring-boot application context (the DemoApplication needs running), what should I do to make it happen?

Answer

Since my application is based on Spring-Boot, and spring-boot-maven-plugin is included in pom.xml, so what I need to do is to add following configuration to make sure the lifecycle of our Spring Boot application is well managed around.

<executions>
  <execution>
    <id>pre-integration-test</id>
    <goals>
      <goal>start</goal>
    </goals>
  </execution>
  <execution>
    <id>post-integration-test</id>
    <goals>
      <goal>stop</goal>
    </goals>
  </execution>
</executions>

Then when I issue mvn clean verify, the spring boot application will be running with our integration test code.
