我有一个类似这样的控制器：

@RestController
@RequestMapping("/api")
public class SimulationController {

@Autowired
    private SimulationRepository simulationRepository;

@PostMapping("/simulations")
    public Simulation createSimulation(@Valid @RequestBody Simulation simulation){
        simulationRepository.save(simulation);

        return simulation;

    }
}

我想知道如何将模拟对象传递给其他控制器，这些控制器可以处理数据并将其保存到其他存储库。例如，它可以如下所示：

@PostMapping("/simulations")
    public Simulation createSimulation(@Valid @RequestBody Simulation simulation){
        simulationRepository.save(simulation);
        SimulationProcess simulationProcess = new SimulationProcess(simulation);
        simulationProcess.simulate();
        return simulation;

    }

@Controller
public class SimulationProcess {
    private Simulation simulation;

    @Autowired
    private SecondRepository secondRepository;

    public SimulationProcess(Simulation simulation) {
        this.simulation = simulation;
    }

    public void simulate(){
    // process data from this.simulation
       secondRepository.save(new Second(...));
    }
}

但我知道这种做法是不允许的。有什么办法吗？
