Tomcat doesn't launch spring

Question

I'm using Ubuntu; I installed Java & jdk :

user@CU-Desktop:~$ java -version
openjdk version "11.0.11" 2021-04-20
OpenJDK Runtime Environment (build 11.0.11+9-Ubuntu-0ubuntu2.20.04)
OpenJDK 64-Bit Server VM (build 11.0.11+9-Ubuntu-0ubuntu2.20.04, mixed mode)
user@CU-Desktop:~$ javac -version
javac 11.0.11

I generate spring boot project from spring initializr, this is the poom.xml file :

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

</project>

Main class :

@SpringBootApplication
public class TestprojectApplication {

    public static void main(String[] args) {
        SpringApplication.run(TestprojectApplication.class, args);
    }

}

Servlet initializer :

public class ServletInitializer extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(TestprojectApplication.class);
    }

}

Next I create a basic entity :

@Entity
@Table(name = "CpAccount")
public class Account {

    @Id
    @Column(name = "Id")
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long id;

    @Column(name = "Login")
    private String login;

    @Column(name = "Password")
    private String password;

    @Column(name = "Email")
    private String email;

    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }

    public String getLogin() {
        return login;
    }

    public void setLogin(String login) {
        this.login = login;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }
}

And set configuration for DB access on application.properties :

spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl
spring.jpa.hibernate.ddl-auto=update
spring.datasource.url=jdbc:mysql:localhost:3306/project_db
spring.datasource.username=myusername
spring.datasource.password=mypassword

The problem is when I launch tomcat, it doesn't launch Spring. The log just notify that tomcat is successfully launched :

Aug 26, 2021 11:25:44 AM org.apache.catalina.startup.Catalina start
INFO: Server startup in [320] milliseconds
