  20.         return new MCPServiceImpl(client);
  21.     }
  22. }

2.2.2 服务层实现

  1. @Service
  2. public class MCPServiceImpl implements MCPService {
  4.     private final BaiduMapClient client;
  6.     public MCPServiceImpl(BaiduMapClient client) {
  7.         this.client = client;
  8.     }
  10.     @Override
  11.     public Mono<RouteResult> calculateRoute(RouteRequest request) {
  12.         return Mono.fromCallable(() -> {
  13.             MCPRequest mcpRequest = new MCPRequest();
  14.             mcpRequest.setOrigin(request.getOrigin());
  15.             mcpRequest.setDestination(request.getDestination());
  16.             mcpRequest.setServiceType("driving");
  18.             return client.execute(mcpRequest, RouteResult.class);
  19.         }).subscribeOn(Schedulers.boundedElastic());
  20.     }
  22.     @Override
  23.     public Mono<List<PlaceInfo>> searchPlaces(String keyword, double longitude, double latitude) {
  24.         // 实现地理编码与POI搜索逻辑
  25.         // ...
  26.     }
  27. }

2.3 控制器层开发（2分钟）

  1. @RestController

  9.     }
  11.     @GetMapping("/route")
  12.     public Mono<ResponseEntity<RouteResult>> getRoute(
  13.             @RequestParam String origin,
  14.             @RequestParam String destination) {
  16.         RouteRequest request = new RouteRequest(origin, destination);
  17.         return mcpService.calculateRoute(request)
  18.             .map(result -> ResponseEntity.ok(result))
  19.             .onErrorResume(e -> Mono.just(ResponseEntity.badRequest().build()));

  6.         ErrorResponse error = new ErrorResponse(
  7.             e.getErrorCode(),
  8.             e.getMessage(),
  9.             LocalDateTime.now()
  10.         );
  11.         return ResponseEntity.status(HttpStatus.SERVICE_UNAVAILABLE)
  12.             .body(error);
  13.     }
  15.     @ExceptionHandler(MethodArgumentNotValidException.class)
  16.     public ResponseEntity<Map<String, String>> handleValidationExceptions(
  17.             MethodArgumentNotValidException ex) {
  18.         // 参数校验错误处理
  19.         // ...
  20.     }
  21. }

三、性能优化与最佳实践

3.1 请求缓存策略

  1. @Configuration
  2. public class CacheConfig {
  4.     @Bean
  5.     public CacheManager cacheManager() {
  6.         return new ConcurrentMapCacheManager("routeCache", "placeCache");
  7.     }
  9.     @Bean
  10.     public MCPService cachedMCPService(MCPService mcpService, CacheManager cacheManager) {
  11.         return new CachingMCPService(mcpService, cacheManager);
  12.     }
  13. }
  15. // 缓存装饰器实现示例
  16. public class CachingMCPService implements MCPService {
  17.     private final MCPService delegate;
  18.     private final CacheManager cacheManager;
  20.     public CachingMCPService(MCPService delegate, CacheManager cacheManager) {
  21.         this.delegate = delegate;
  22.         this.cacheManager = cacheManager;
  23.     }
  25.     @Override
  26.     public Mono<RouteResult> calculateRoute(RouteRequest request) {
  27.         String cacheKey = "route:" + request.getOrigin() + ":" + request.getDestination();
  28.         Cache cache = cacheManager.getCache("routeCache");
  30.         return Mono.deferContextual(ctx -> {
  31.             Context context = ctx.getOrDefault(Context.class, Context.empty());
  32.             return Mono.justOrEmpty(cache.get(cacheKey, RouteResult.class))
  33.                 .switchIfEmpty(delegate.calculateRoute(request)
  34.                     .doOnSuccess(result -> cache.put(cacheKey, result)));
  35.         });
  36.     }
  37. }

3.2 批量请求处理

  1. public class BatchMCPService implements MCPService {
  3.     private final MCPService delegate;
  4.     private final int batchSize = 50;
  6.     public BatchMCPService(MCPService delegate) {
  7.         this.delegate = delegate;
  8.     }
  10.     @Override
  11.     public Flux<RouteResult> calculateRoutes(List<RouteRequest> requests) {
  12.         return Flux.fromIterable(requests)
  13.             .buffer(batchSize)
  14.             .flatMap(batch -> {
  15.                 List<Mono<RouteResult>> monos = batch.stream()
  16.                     .map(req -> delegate.calculateRoute(req))
  17.                     .collect(Collectors.toList());
  18.                 return Flux.mergeSequential(monos);
  19.             });
  20.     }
  21. }

  1. 环境变量注入：

    1. @Bean
    2. public String accessKey() {
    3.  return System.getenv("BAIDU_MAP_AK");
    4. }

  2. Vault集成示例：

    1. @Configuration
    2. public class VaultConfig {
    4.  @Bean
    5.  public BaiduMapCredentials baiduMapCredentials(VaultTemplate vaultTemplate) {
    6.      VaultResponse response = vaultTemplate.read("secret/baidu-map");
    7.      return new BaiduMapCredentials(
    8.          response.getData().get("ak"),
    9.          response.getData().get("sk")
    10.      );
    11.  }
    12. }

4.2 请求签名验证

  1. public class MCPRequestSigner {
  3.     public static String signRequest(MCPRequest request, String secretKey) {
  4.         String timestamp = String.valueOf(System.currentTimeMillis());
  5.         String nonce = UUID.randomUUID().toString();
  7.         String rawSign = String.join("\n",
  8.             request.getServiceType(),
  9.             request.getOrigin(),
  10.             request.getDestination(),
  11.             timestamp,
  12.             nonce,
  13.             secretKey
  14.         );
  16.         try {
  17.             MessageDigest md = MessageDigest.getInstance("SHA-256");
  18.             byte[] digest = md.digest(rawSign.getBytes(StandardCharsets.UTF_8));
  19.             return Base64.getEncoder().encodeToString(digest);
  20.         } catch (NoSuchAlgorithmException e) {
  21.             throw new RuntimeException("SHA-256 algorithm not found", e);
  22.         }
  23.     }
  24. }

  8.     private MCPService mcpService;
  10.     @Test
  11.     void calculateRoute_ShouldReturnSuccess() {
  12.         RouteRequest request = new RouteRequest("北京", "上海");
  13.         RouteResult expected = new RouteResult(...);
  15.         when(client.execute(any(MCPRequest.class), eq(RouteResult.class)))
  16.             .thenReturn(expected);
  18.         StepVerifier.create(mcpService.calculateRoute(request))
  19.             .expectNext(expected)
  20.             .verifyComplete();
  21.     }
  22. }

  23.         Timer timer = registry.timer("mcp.route.time");
  24.         Counter counter = registry.counter("mcp.route.count");
  26.         return timer.record(() -> 
  27.             delegate.calculateRoute(request)
  28.                 .doOnSuccess(r -> counter.increment())
