@SpringBootTest is not loading the properties from @ConfigurationProperties

Question

When I run mvn clean install or mvn spring-boot:run, my integration test or application start is not loading properties from the application properties, but when I run the test from intelliJ Idea, or starts the server through intellij, it works fine. My codes are as below:

@Data is a lombok.Data, which generates getter and setter at compile time

package com.a.configuration;
@Data
@ConfigurationProperties(prefix = "my.service")
@Configuration
public class PropertyConfig {    
    private Integer pageSize;
    private Integer maxPageCount;
}

---

    package com.a.service;    
    @RunWith(SpringRunner.class)
    @SpringBootTest(webEnvironment= SpringBootTest.WebEnvironment.RANDOM_PORT, classes = Application.class)
    public class DataLoadIT {
    }

I also tried @EnableConfigurationProperties with no luck:

package com.a.configuration;    
@Configuration
@EnableConfigurationProperties(PropertyConfig.class)
public class MyConfiguration {
}

---

    package com.a;
    @SpringBootApplication
    public class Application {
        public static void main(String[] args) {
            SpringApplication.run(Application.class, args);
        }
    }

My project structure is: src/main/java src/test/java src/integration-test/java

And using the below plugin to separate the unit test and integration-test:
