  • Please set the org.springframework.boot.SpringApplication as the main class.
  • At least one main config class as a source must be added,like as below.
  • Add scanBasePackages=”com.spring” at the main class.

 

@SpringBootApplication
@EnableScheduling
@EnableJpaRepositories("com.spring.data")
@ComponentScan(basePackages = "com.spring.util")
@EntityScan(basePackages = "com.spring.bean")
public class SpringBootWebApplication {

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

}

 

Try this,your application will work.
