我们有一项服务可以对 USPS 地址验证服务进行 REST 调用。我们最近升级到新版本的电子商务框架 (Broadleaf Commerce)，并更新了 Spring Boot 和 Java 版本。自升级后，我们无法再连接到 USPS 服务。我们失败了，因为 SSL 握手没有完成（似乎更改密码请求从未得到答复）。代码的现有生产版本按原样工作。
奇怪的是它在本地工作，如果我从目标服务器发出 cURL 请求，它就可以工作。但是当我从目标服务器上的应用程序进行调用时，它没有完成握手。
我一直在互联网和堆栈溢出中搜索答案，但没有找到可以解决我的问题的答案。以下是我迄今为止遵循的故障排除步骤：
jdk.tls.client.protocolshttps.protocols我不知道要测试什么来确定问题的根本原因。似乎与代码无关（代码在本地运行），似乎与服务器网络/防火墙无关（cURL 在服务器上运行）。
还剩下什么？我错过了什么？
错误信息：
org.springframework.web.client.ResourceAccessException: I/O error on POST request for "https://stg-secure.shippingapis.com/ShippingAPI.dll": Remote host terminated the handshake; nested exception is javax.net.ssl.SSLHandshakeException: Remote host terminated the handshake
RestCall 代码：
@Value("${usps.addressValidation.url}")
private String url;
private ResponseEntity<String> callUsps() {
Map<String, String> uriVariables = new HashMap<>();
uriVariables.put("userId", apiKey);
... more variables ...
ResponseEntity<String> response = restTemplate.postForEntity(url, null, String.class, uriVariables);
}
RestTemplate 配置：
@Bean
public RestTemplate restTemplate() {
RestTemplate restTemplate = new RestTemplate();
restTemplate.setRequestFactory(new HttpComponentsClientHttpRequestFactory()); // HttpComponents added for debug logging purposes, originally it was stock rest template
return restTemplate;
}
