贝宝沙盒 API：javax.net.ssl.SSLHandshakeException：收到致命警报：handshake_failure
Paypal Sandbox API: javax.net.ssl.SSLHandshakeException: Received fatal alert: handshake_failure
我在沙盒模式下使用 PayPal MassPay API 时出现异常。
同样的代码之前工作，现在它给了我一个 SSLHandshakeException。我认为这是因为 PayPal 最新的 SSL 认证更新。有人可以帮我解决这个问题吗？
以下是我的异常日志：

看起来您使用的是旧版本的 TLS。 PayPal 最近（几天前）对他们的沙箱进行了更改，要求所有连接都通过 HTTP 1.1 和 TLS 1.2 完成。尝试将您的代码设置为使用更新版本的 TLS (1.2)，看看是否有帮助。显然它对这里的很多人都有效。
Link 到 PayPal 开发博客上的更改说明
https://devblog.paypal.com/upcoming-security-changes-notice/
问题是 PayPal 最近（1 月 19 日或 20 日）将沙箱切换到 TLS 1.2，不再支持 TLS 1。我猜您是 运行 Java SE 7 或更早版本。如果您稍微搜索一下网络，您会发现：
Although SunJSSE in the Java SE 7 release supports TLS 1.1 and TLS
1.2, neither version is enabled by default for client connections. Some servers do not implement forward compatibility correctly and
refuse to talk to TLS 1.1 or TLS 1.2 clients. For interoperability,
SunJSSE does not enable TLS 1.1 or TLS 1.2 by default for client
connections.
要启用 TLS 1.2，您可以使用 VM 的以下设置：-Dhttps.protocols=TLSv1.1,TLSv1.2 然后它将起作用。
如果您想查看有关握手的更多详细信息，可以使用此 VM 选项：-Djavax.net.debug=all
如果您看到类似这样的内容，则可以确认 TLS 1.2 已禁用：
*** ClientHello, TLSv1
读取服务器响应后将抛出异常。 Java8没有这个问题，因为TLS 1.2是默认开启的
目前只有沙盒受到影响。您可以在 PayPal 的网站上阅读：
PayPal is updating its services to require TLS v1.2 for all HTTPS
connections on June 17, 2016. After that date, all TLS v1.0 and TLS
v1.1 API connections will be refused.
很可能这会被推迟得更久。
您可以重现问题并使用这个简单的 throw-away 代码进行试验：
URL sandbox = new URL("https://api.sandbox.paypal.com/v1/oauth2/token");
URLConnection yc = sandbox.openConnection();
BufferedReader in = new BufferedReader(new InputStreamReader(
yc.getInputStream()));
String inputLine;
while ((inputLine = in.readLine()) != null)
System.out.println(inputLine);
in.close();
这周我一直在处理同样的问题（Paypal TLS 1.2 与 JRE 1.6）。经过一些疯狂的时间，我设法使用 BouncyCastle 和一些我并不引以为豪的代码解决了这个问题（就像一个补丁。持久的解决方案将升级到 JRE 1.8）。
