javax.net.ssl.SSLHandshakeException（在applet中握手期间远程主机关闭连接） _handshake

追风赶月莫停留，平芜尽处是春山。这篇文章主要讲述javax.net.ssl.SSLHandshakeException：在applet中握手期间远程主机关闭连接相关的知识，希望能为你提供帮助。
在我的Web应用程序中，我使用的是一个名为jar的applet，这个applet在jre 1.6和1.7之前工作正常。但是在安全弹出和applet的阻塞错误后，我们不得不购买了一个java代码签名证书。
我已经成功签署了这个applet jar，这个applet在HTTP协议上没有任何问题。如果我在HTTPS上打开此applet，它会开始提供SSLHandshakeException的异常。我已经尝试了所有可能的解决方案来运行它，但它失败了。

在applet中，我使用简单的applet

import java.applet.*; import java.awt.*; public class Apps extends Applet{public void paint(Graphics g){ g.drawString("Welcome in Java Applet.",40,20); } }

答案我们遇到了同样的问题。我相信这是Java为SSL实现TLS 1.2的方式中的一个错误。
根据他们的文档https://blogs.oracle.com/java-platform-group/entry/java_8_will_use_tls，他们声称通过启用TLS 1.2，它向后兼容旧版本。
然而，这种情况并非如此。禁用TLS 1.2后，我们不再获得“握手期间远程主机关闭连接”错误。
可以从Java控制面板中的“高级设置”关闭TLS 1.2支持。
完成后，applet将起作用。
另一答案在我们的例子中，我们得到了相同的例外。但对于java1.6和1.7我们的环境如下：
