Null Service Instance with @Autowired

Question

Hello, everyone. I am making a Springboot REST webservice application with JAVA. I need a method to run from time to time. For this, I am using Quartz (org.Quartz). The class method is executed in the time I want, normally. However, this method instantiates a controller to execute a search method in the database, and this search method is not working.

The instantiated controller class uses a Service interface with Annotation @Autowired. When I try to execute some method of the controller that uses this interface, it gives an error saying that it is null.

I even tried to search the bank directly for the class executed periodically, but accuses that Entitymanager is null.

EDITED

Guys, I managed to find the solution by researching a lot. I leave here the solution: https://stackoverflow.com/questions/11965600/how-do-i-manually-autowire-a-bean-with-spring.

Answer 1

I did a lot of research and I was able to find the solution and the reason for the problem.

• The reason:

  It is not possible to instantiate manually Beans as this is totally out in the concept of Ioc.

• The solution:

  https://stackoverflow.com/questions/11965600/how-do-i-manually-autowire-a-bean-with-spring

Example of the link:

B bean = new B();
AutowireCapableBeanFactory factory = applicationContext.getAutowireCapableBeanFactory();
factory.autowireBean( bean );
factory.initializeBean( bean, "bean" );
