java - 我在来自 Java 客户端的 Http Post 请求中收到无效参数错误

Question

我正在从 IBM I 系列服务器上的 pojo java 应用程序发出 HTTP Post 请求。

    HttpResponse response = httpclient.execute(httppost);

大约 3 秒后我收到此错误。

我已经确定我们使用的是 TLS 1.2 并且 java 版本是 1.8

客户端 - 代码片段 -

CloseableHttpClient httpclient = 

HttpClientBuilder.create().setDefaultRequestConfig(config).build();
HttpPost httppost = new HttpPost("https://lb1.cardknox.com/gateway");

SSLContext sslContext = SSLContext.getInstance("TLSv1.2");
sslContext.init(null, null, null);
SSLContext.setDefault(sslContext);

HttpResponse response = httpclient.execute(httppost); 

注意:当我从我的 eclipse 工作台使用它时它工作正常 - 我只有在 IBM 服务器上运行它时才会遇到问题。

IBM Websphere 服务器使用 IBM JRE 而不是 Oracle JRE。这是引述。

The IBM implementation of SSLContext.getInstance("TLS") is different from the Oracle implementation.

另请查看以下引用

If you set the system property com.ibm.jsse2.overrideDefaultTLS=true and you enable either SP800-131a strict compliance (com.ibm.jsse2.sp800-131) or Suite B (com.ibm.jsse2.suiteB) system properties, only the TLS V1.2 protocol is enabled.
