我们遇到中间连接超时问题。我使用的是 Java 21 和 Spring Boot 版本 3.1.6。应用程序在内部调用 Amadeus API 来收集数据。我的应用程序充当这些 API 的包装器。我们使用了超过 35 个 API，因此有时会遇到连接超时的情况。我们针对 Amadeus API 集成了负载测试，该测试始终返回正确的响应，没有任何问题。类似的应用程序也遇到了同样的问题。所有这些应用程序都使用 Java 21，它们也使用其他服务，而不是 Amadeus API。
有人对这个问题有任何想法吗？
供您参考，我已将 RestTemplate 配置添加到此问题中。这对我找到这个问题的根本原因非常有帮助。
@Bean(name = "restTemplate")
@Scope(scopeName = "request", proxyMode = ScopedProxyMode.TARGET_CLASS)
public RestTemplate restTemplate(RestTemplateBuilder builder) {
return configureRestTemplate(builder);
}
private RestTemplate configureRestTemplate(RestTemplateBuilder builder) {
RestTemplate restTemplate = new RestTemplate(new BufferingClientHttpRequestFactory(new SimpleClientHttpRequestFactory()));
List<ClientHttpRequestInterceptor> interceptors = new ArrayList<>();
interceptors.add(new LoggingRequestInterceptor());
restTemplate.setInterceptors(interceptors);
if (CollectionUtils.isEmpty(interceptors)) {
interceptors = new ArrayList<>();
}
HttpComponentsClientHttpRequestFactory requestFactory = new HttpComponentsClientHttpRequestFactory();
restTemplate.setRequestFactory(requestFactory);
return restTemplate;
}
API调用端代码如下：
@Autowired
private RestTemplate restTemplate;
。 。 .
private <T, U> U exchangeData(URI uri, T data, Class<U> clazz, HttpHeaders requestHeaders, HttpMethod method,
boolean... errorCustomization) {
HttpEntity<T> requestEntity = new HttpEntity<>(data, requestHeaders);
ResponseEntity<U> response = null;
try {
response = restTemplate.exchange(uri, method, requestEntity, clazz);
} catch (RestClientException e) {
List<ErrorModel> errorDetails = new ArrayList<>();
errorDetails.add(new ErrorModel(e.getClass().getName(), e.getMessage()));
LOG.error("Error while calling external service", e);
throw applicationErrorConfig.createExternalException(ApiExternalErrorType.SERVER_INTERNAL_ERROR,
errorDetails);
}
restErrorManagerUtil.handleExternalServerErrorForComposite(data, response.getBody(), errorCustomization);
return response.getBody();
}
还添加堆栈跟踪
