java - Spring Boot Controller 未被映射

Question

我正在尝试创建一个基本的 SpringBoot Web 应用程序，其中一个端点名为/movies。我遵循了网站上的一些文档以及有关它的基本 YouTube 教程。

当我从命令行运行 curl localhost:8080 时，应用程序返回“它有效”，但当我尝试访问我的端点/movies 时，我看到“在此服务器上找不到请求的 URL /movies。'

主类:

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

Controller 类:

@RestController
@RequestMapping("/movies")
public class MovieController {

    @Autowired
    private MovieService movie_service;

    @RequestMapping(method = RequestMethod.GET)
    public Collection<Movie> getAllMovies(){
        return movie_service.getAllMovies();
    }
}

</project>

对于发布的类似问题，我几乎尝试了该网站上的所有建议答案，但似乎没有任何解决办法。一件不寻常的事情是，当我在命令行中运行应用程序时，我看不到映射:

感谢任何帮助。

尝试像这样改变你的类(class)。只需在方法级别使用 GetMapping 即可。另请注意，我已将您的服务重命名为标准 Java 命名约定 (camelCase)。

@RestController
public class MovieController {

    @Autowired
    private MovieService movieService;

    @GetMapping("/movies")
    public Collection<Movie> getAllMovies(){
        return movieService.getAllMovies();
    }
}
