【问题描述】：
我正在尝试在 Java 7、Ubuntu Linux 下使用 HTML Unit 2.23 获取 HTTPS 页面 https://portal.mvp.bafin.de/database/AnteileInfo/。 p>
以下代码在几天前仍然有效，但现在我收到下面报告的异常。
问题应该与使用的安全证书的类型有关，但是在我阅读时使用 vm 选项 "-Dhttps.protocols=TLSv1.1,TLSv1.2" 执行代码没有任何改变here
代码：
import java.io.IOException;
import java.net.MalformedURLException;
import com.gargoylesoftware.htmlunit.FailingHttpStatusCodeException;
import com.gargoylesoftware.htmlunit.WebClient;
import com.gargoylesoftware.htmlunit.html.HtmlPage;
public class SSLTest {
public static void main(String[] args) throws FailingHttpStatusCodeException, MalformedURLException, IOException {
final String URL = "https://portal.mvp.bafin.de/database/AnteileInfo/";
final WebClient wc = new WebClient();
// the code should be ok without the following line,
// but even with it, it doesn't work
// wc.getOptions().setSSLClientProtocols(new String[]{"TLSv1.1","TLSv1.2"});
final HtmlPage mainPage = wc.getPage(URL);
}
}
例外情况如下：握手期间远程主机关闭连接

如果取消注释以下行
wc.getOptions().setSSLClientProtocols(new String[]{"TLSv1.1","TLSv1.2"});
我得到下面的异常，它给出了一个稍微不同的消息：fatal alert: handshake_failure

有什么建议吗？

显然，将 Java 版本更改为 1.8 可以解决问题：github.com/SeleniumHQ/htmlunit-driver/issues/8

谢谢，我已经升级到 java 8 但这是正确的答案
