如何解决此问题？
它也与apache httpClient一起出现。
在junit测试中运行良好，或者在我的本地计算机上的
中都无法正常运行添加证书，但在远程开发环境中失败，
看起来像是因为其上的应用程序包含此
--add-exports java.base/sun.security.util=ALL-UNNAMED --add-exports java.base/sun.security.pkcs10=ALL-UNNAMED --add-exports java.base/sun.security.jca=ALL-UNNAMED --add-exports java.base/sun.security.rsa=ALL-UNNAMED --add-exports java.base/sun.security.pkcs=ALL-UNNAMED --add-exports java.base/sun.security.tools.keytool=ALL-UNNAMED --add-exports java.base/sun.security.x509=ALL-UNNAMED
无法删除它，因为当前代码使用sun.security。*。
在我看来，这些出口 OR 会导致另一种情况
javax.net.ssl|WARNING|01|main|2019-05-25 09:00:19.195 EDT|SignatureScheme.java:282|Signature algorithm, SHA256withECDSA, is not supported by the underlying providers
但看起来这不是简单的警告，主要例外

Java版本是11.0.3。
没有帮助
SSLContext sslContext = SSLContext.getInstance("TLSv1.3", "SunJSSE");
sslContext.init(null, trustAllCerts, new SecureRandom());
return sslContext;//to http client
