Question

I am totally new to Spring and started to do the official guides from this site: https://spring.io/guides

I\'d like to do this guide: https://spring.io/guides/gs/sch

Answer 1

A scan of the @SpringBootApplication show that it includes the following annotations:

@Configuration
@ComponentScan
@EnableAutoConfiguration

So you could do this too:

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

Answer 2

Probably you missing @SpringBootApplication in your spring boot starter class.

@SpringBootApplication
public class LoginSecurityAppApplication {

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

}

Answer 3

I've had similar problems when the main method is on a different class than that passed to SpringApplcation.run()

So the solution would be to use the line you've commented out:

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

Answer 4

I had a similar issue and the problem was a broken maven repo jar file. In my case, the tomcat-embed-core jar file was broken. So I removed it from the maven repo and refreshed it to download again.

Answer 5

I had multiple application classes in one Spring Boot project which had the web started included and wanted to avoid it configuring a web environment for one of them so I manually configured it as below:

@SpringBootApplication
public class Application
{
    public static void main(String[] args)
    {
        new SpringApplicationBuilder(Application.class)
            .web(false)
            .run(args);
    }
}

UPDATE for Spring Boot 2 and above:

@SpringBootApplication
public class Application
{
    public static void main(String[] args)
    {
        new SpringApplicationBuilder(Application.class)
            .web(WebApplicationType.NONE)
            .run(args);
    }
}

Answer 6

check your pom.xml is exists

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-tomcat</artifactId>
    </dependency>

I've had a problem like this；For lack this dependency
