我从 0 开始我的第一个 api 项目。我从 spring 初始化程序下载了启动项目,然后开始在其中编写代码。但现在我有一个小问题。似乎主类无法识别我创建的 Controller ,因为我尝试将 Controller 的代码放入主类中并且它可以工作,在实际状态下它给我“路径未找到404”错误。

我是否必须在某个地方添加 Controller ?

提前致谢!

主类

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class ApiDispatcherApplication {

public static void main(String[] args) {
SpringApplication.run(ApiDispatcherApplication.class, args);
}
}

Controller

import model.ApiModel;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;

@RestController
public class WebController {

@Autowired
public WebController(){

}

@RequestMapping(path = "/sample", method = RequestMethod.GET)
public ApiModel Sample(@RequestParam(value = "name", defaultValue = "Robot") String name){
ApiModel response = new ApiModel();
response.setResponse("Your name is " + name);
return response;
}
}

此时它给了我 404,但是如果我将 Controller 代码直接放在主类中,它就可以工作

最佳答案

谢谢@dassum,我用这种方式解决了我的问题:

主类

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
@ComponentScan("controller") //controller is the name of the folder of my controllers
public class ApiDispatcherApplication {

public static void main(String[] args) {
SpringApplication.run(ApiDispatcherApplication.class, args);
}
}

希望我通过这篇文章帮助了其他一些初学者:)

谢谢@dassum!
