Service instance null with @Autowired

Navigation
0

Hello everyone. I'm doing a webservice REST SpringBoot application with JAVA. I need a method to run from time to time. For this, I'm using Quartz (org.quartz). The class method is executed at the time I want, normally. However, this method instantiates a controller to execute a search method on the database, and this search method is not working.

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

I have already tried to search the database directly for the class executed periodically, but it accuses the EntityManager is null.

StackTrace:

I researched a lot and was able to find the solution and the reason for the problem.

  • The reason:

      

    It is not possible to manually instantiate beans, as this is totally outside the IoC concept.

  • The solution:

Link example: 

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