Currently, I'm trying to develop a Mock API platform in Spring Boot that can create a mock RESTful endpoints for developer testing purposes. Specifically, I need to create a system where user can define their custom API endpoints, request and expected responses similar to swagger, mockapi.io, ...

目前，我正在尝试在Spring Boot中开发一个Mock API平台，该平台可以创建一个用于开发人员测试目的的模拟RESTful端点。具体地说，我需要创建一个系统，在其中用户可以定义他们的自定义API端点、请求和预期的响应，类似于swagger、mock api.io、...

For starter, I try a naive solution which compile a controller Java class at runtime and try to access that API endpoint but not working. Seem like, the Spring Bean Container cannot understand a new Controller Bean at runtime.

对于初学者，我尝试了一种简单的解决方案，即在运行时编译一个控制器Java类，并尝试访问该API端点，但无法正常工作。看起来，Spring Bean容器在运行时无法理解新的Controller Bean。

App.java

App.java

    public static void main(String[] args) throws ClassNotFoundException, IOException {
        var context = SpringApplication.run(ApiSimulationApplication.class, args);
        CreationService service = new CreationService();
        Path mockControllerPath = service.createMockControllerFile();
        service.compileFile(mockControllerPath);
    }

MockController.java (created at runtime)

Java(在运行时创建)

@RestController
public class MockController {
    public MockController() {}

    @GetMapping({"/mock"})
    public String sayHello() {return "Hello";}
}

Even if I try to refresh the ApplicationContex, it will throw:

即使我尝试刷新ApplicationContex，它也会抛出：

GenericApplicationContext does not support multiple refresh attempts

I could not think of any other solution or may be I have been following the wrong direction, so I am here to seek for advice and recommendations.
I am looking forward and really appreciate your help.

我想不出任何其他的解决办法，或者可能是我走错了方向，所以我在这里征求意见和建议。我很期待，真的很感谢你的帮助。
