您好,我正在使用连接到 mongo db 的 Spring boot 应用程序,我的问题是我的端点无法正常工作,似乎组件扫描没有找到它们。我已经疯了,因为我被阻止继续开发并且我无法确定问题所在。一切似乎都很好。我想这可能与版本有关,但不太确定。
这是我的控制器:
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);
}
}
