Question

你好，我正在使用连接到mongo db的Spring boot App，我的问题是我的端点无法正常工作，看来组件扫描找不到它们。我一直在疯狂，因为我被阻止继续开发，并且无法确定问题所在。一切似乎还好。我想这可能与版本有关，但不确定。

这是我的控制者：

package com.mercadolibre.mutants.controllers;

import com.mercadolibre.mutants.entities.Product;
import java.util.concurrent.CompletableFuture;
import javax.servlet.http.HttpServletRequest;
import javax.validation.Valid;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.http.HttpStatus;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseStatus;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class ProductController {

  private static final Logger LOGGER = LoggerFactory.getLogger(ProductController.class);
  public static final String SHORTEN_URL_PATH = "/shorten";
  public static final String URL_PATH = "/{id}";

  
  @RequestMapping(value = SHORTEN_URL_PATH, method = RequestMethod.POST)
  @ResponseStatus(HttpStatus.CREATED)
  public CompletableFuture<String> shortenUrl(@RequestBody @Valid final Product shortenUrlDto, HttpServletRequest request) throws Exception {
    LOGGER.info("Url to shorten: " );
    CompletableFuture<String> shortenedUrl = null;
    String localURL = request.getRequestURL().toString();
    //shortenedUrl = shortUrlService.shortenURL(localURL, shortenUrlDto.getUrl());
    LOGGER.info("Shortened url to: " + shortenedUrl);
    return shortenedUrl;
  }

  @GetMapping(URL_PATH)
  public CompletableFuture<String> retrieveOriginalUrl(@PathVariable String id) throws Exception {
    LOGGER.info("short url to redirect: " + id);
    //CompletableFuture<String> redirectUrlString = shortUrlService.getLongURLFromID(id);
    //  LOGGER.info("Original URL: " + redirectUrlString);
    return null;
  }
}

这是我的应用程序类：

package com.mercadolibre.mutants;

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

@SpringBootApplication()
public class MutantsApplication {

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

}

从评论中，我会说您在部署api的docker配置方面有问题，我将进行下一个验证：

检查docker容器中8080是否已提供您的api。
检查是否已正确配置docker容器，以便打开8080端口（或api使用的端口）。
检查（出于某些奇怪的原因）您是否在Docker容器中的8080中没有运行其他api。

最后，进入容器的SSH，然后（如果您正在运行UNIX SO）对URL发出CURL请求并检查答案。

希望这会有所帮助。
