我正在尝试与外部网络服务集成,它使用带有TLS 1.0协议的证书。
我尝试设置-Dhttps.protocols=TLSv1,TLSv1.1,TLSv1.2,SSLv3
但出站网关仍然使用 TLSv1.2
.如果我只是将选项限制为 TLSv1
,它可以正常工作,但我无法做到这一点,因为我正在集成到许多外部服务。
如何在出站网关本身上设置协议?
我尝试使用此代码执行此操作,但遇到了异常:
SimpleWebServiceOutboundGateway handler = new SimpleWebServiceOutboundGateway(url);
HttpComponentsMessageSender sender = new HttpComponentsMessageSender();
SSLContext sslContext = SSLContext.getDefault();
sslContext.getDefaultSSLParameters().setProtocols(new String[]{"TLSv1"});
CloseableHttpClient httpClient = HttpClients.custom().setSSLContext(sslContext).build();
sender.setHttpClient(httpClient);
handler.setMessageSender(sender);
例外:

我查看了 HttpComponentsMessengerSender 的相关文档,发现了 HttpComponentsMessageSender.RemoveSoapHeadersInterceptor
HttpClient HttpRequestInterceptor 实现,用于从请求中删除内容长度和传输编码标头。这是必需的,因为某些 SAAJ 和其他 SOAP 实现会自行设置这些标头,如果已设置这些标头,则 HttpClient 会引发异常。
解决方案是将其添加到HttpComponentsMessengerSender
的拦截器中。
发件人的最终版本是:
SSLContext sslContext = SSLContexts.custom().useProtocol("TLSv1").build();
CloseableHttpClient httpClient = HttpClients.custom()
.setSSLContext(sslContext)
.addInterceptorFirst(new
HttpComponentsMessageSender.RemoveSoapHeadersInterceptor())
.build();
HttpComponentsMessageSender sender = new HttpComponentsMessageSender(httpClient);
