Spring-Boot error:404 error in loading the template - spring

Question

in my spring boot application i have the following pom.xml:
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.5.7.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
</dependencies>
as controller i have the simple one as below:
#Controller
public class ThyemeleafController {
#RequestMapping("/")
public String home() {
return "home";
}
}
and then i have a simple home.html in the src/main/resources/templates which contains helloWorld. But when i run the application and go to url:
http://localhost:8080/
it complains with:
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Not Found, status=404).
No message available

Answer 1

I got my answer. I wrote my controller in another package so, i must ask the spring boot to scan that package and make the essential beans from it:
#SpringBootApplication
#ComponentScan("com.eventer.controller")
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}
