Answer 1

您正在尝试创建与没有官方ssl证书的服务器的SSL连接。您可以通过将服务器证书导入Java证书库来解决此问题。看这里 SSL Exception: javax.net.ssl.SSLHandshakeException: Received fatal alert: certificate_unknown 或者在这里 https://docs.oracle.com/javase/tutorial/security/toolsign/rstep2.html 了解更多信息

Answer 2

此问题已解决

EmployeeBasicDataResponseMessageSync responses= port.findBasicDataByIdentification(employeeBasicDataByIdentificationQuerySync);

**在上面提到的行**

之前添加此代码

SSLContext sc = SSLContext.getInstance("SSL");
                        TrustManager[] trustAllCerts = null;
                        sc.init(null, trustAllCerts, new java.security.SecureRandom());
                    HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());

java sslhandshake异常证书未知
