java如何在Spring中从不同的控制器调用RestController方法？

Question

我有一个RestController，看起来像这样：

@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，该控制器可以处理数据并将其保存到其他存储库。例如，它可能看起来像这样：

@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(...));
    }
}

但我知道这是不允许的。有没有办法做到这一点

我认为您可以在模拟过程类中使用@Service而不是@Controller，您可以将它注入到第一个控制器并使用它，但您不能将请求映射到服务（我认为）

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

    @Autowired
    private SimulationRepository simulationRepository;

    @Autowired
    private SimulationProcess simulationProcess;

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

        simulationProcess.simulate(simulation);
       
        return simulation;

    }
}

@Service
public class SimulationProcess {

    @Autowired
    private SecondRepository secondRepository;

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