Spring集成:强制Webservice出站网关使用TLSv1

spring-integration web-services spring java

Bob Santos · 技术社区 · 6 年前

我正在尝试与外部webservice集成,它使用TLS 1.0协议的证书。

我试过设置 -Dhttps.protocols=TLSv1,TLSv1.1,TLSv1.2,SSLv3 但出站网关仍使用 TLSv1.2 . 如果我将选项限制为 TLSv1 但我不能这样做,因为我正在整合许多外部服务。

如何在出站网关本身上设置协议?

我试着用这段代码做到这一点,但遇到了一个异常:

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);

例外情况:

我查看了HttpComponentsMessengerSender的相关文档,发现 HttpComponentsMessageSender.RemoveSoapHeadersInterceptor

HttpClient HttpRequestInterceptor实现,从请求中删除内容长度和传输编码头。这是必要的,因为一些SAAJ和其他SOAP实现自己设置了这些头,如果设置了这些头,HttpClient会抛出异常。

解决方案是将其添加到 HttpComponentsMessengerSender .

发送方的最终版本为:

SSLContext sslContext = SSLContexts.custom().useProtocol("TLSv1").build();
CloseableHttpClient httpClient = HttpClients.custom()
            .setSSLContext(sslContext)
            .addInterceptorFirst(new 
HttpComponentsMessageSender.RemoveSoapHeadersInterceptor())
            .build();

HttpComponentsMessageSender sender = new HttpComponentsMessageSender(httpClient);
