@configuration @componentscan public class application{ public static void main(string[] args) { springapplication.run(application.class, args); } } i trying configure properties of spring through java classes using @bean:

it seems me embeddedservletcontainerfactory bean not initialized. need kick off:
add @springbootapplication annotation application class
@springbootapplication public class application { public static void main(string[] args) { springapplication.run(scheduledtasks.class, args); } } the @springbootapplication annotation contains
- @configuration
- @componentscan
- @enableautoconfiguration (this 1 might fix problem)
also might need add spring-boot-starter-web dependency in pom:
<dependency> <groupid>org.springframework.boot</groupid> <artifactid>spring-boot-starter-web</artifactid> </dependency>
