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

篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了javax.net.ssl.SSLHandshakeException：在applet中握手期间远程主机关闭连接相关的知识，希望对你有一定的参考价值。

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：

  • jbossAS5.1带有已部署的Web应用程序和该Web应用程序中的一个applet
  • apache web server2.2.1需要客户端证书（自签名）
  • 在客户端mozilla和资源管理器上使用导入的客户端证书，jre与导入的客户端证书

在jre控制面板中，我们禁用了SSL2客户端hello格式，并且还禁用了SSL3和TLS1.2我们只启用了TLS1.0和TLS1.1，从那时起一切正常。
