Hope that helps Ok i found the Solution, the Environment.class was injected into the DTO, which doesn't work at all. I just forgot to map the Environment.class to EnvironmentResponse.class

will help you I am trying to schedule a job using Quartz in Spring boot. below are the code which I am using below are my configurations... , I was able to fix the issue by changing SchedulerFactoryBean
@Autowired
  HCJobFactory jobFactory;

  @Autowired
  DataSource dataSource;

  @Autowired
  ApplicationContext applicationContext;


  @Override
  public void afterPropertiesSet() throws Exception
  {
    setJobFactory( jobFactory.getJobFactory() );
    setApplicationContext(applicationContext);
    setDataSource( dataSource );
    //setTransactionManager( transactionManager );
    super.afterPropertiesSet();
  }

Transaction inside transaction support? (multi database) in Spring boot

Does that help @Transaction annotation has an attribute rollbackFor (@Transaction(value = "DB1", rollbackFor = SqlException.class) for example) that may cover your needs.
However, there is only one transaction will be actually used in your code, because B is invoked not via Spring proxy but via inner call (this.B()). To execute method inside a separate transaction method must be invoked via Spring proxy - someService.B(), not this.B().

How spring transaction works in this example and how to resolve LazyInitializationException?

help you fix your problem I am getting org.hibernate.LazyInitializationException exception. What I know is, the issue is caused because I have fetched profile object in user entity lazily and before proxy object gets initialized the session is closed. ,
Is the session closed after executing findAll() method?

LazyInitializationException Spring Boot

To fix the issue you can do Because the FetchType of Brand is lazy, it will not automatically be loaded into the session with call to fetchAll(). To have it automatically load into the session, you need to:
Change
@ManyToOne(cascade=CascadeType.ALL, fetch = FetchType.LAZY)
@JoinColumn(name="brand_id", referencedColumnName="id")
private Brand brand;
@ManyToOne(cascade=CascadeType.ALL, fetch = FetchType.EAGER)
@ManyToOne(cascade=CascadeType.ALL, fetch = FetchType.EAGER)
@JoinColumn(name="brand_id", referencedColumnName="id")
private Brand brand;
@Component
public CarService implements ICarService {

    @Autowired
    CarRepository carRepository;

    @Transactional
    public void printAllCars() {
        for (Car c : carRepository.findAll()) {
            System.out.println(c.toString());
        }
    }   
}
