如何在Java 7中启用TLS 1.2 [英] How to enable TLS 1.2 in Java 7

问题描述

我正在尝试在使用JBoss 6.4和Java 1.7的Web应用程序中启用TLS 1.2。我在我的应用程序环境中有 -Dhttp.protocols = TLSv1.2 ，但它似乎对我不起作用。

I am trying to enable TLS 1.2 in my web app which uses JBoss 6.4 and Java 1.7. I have -Dhttp.protocols = TLSv1.2 in my application environment but it doesn't seem to work for me.

我能做些什么来启用TLS 1.2？

Is there anything I could do to enable TLS 1.2?

我写了一个简单的程序

context = SSLContext.getInstance("TLSv1.2");
context.init(null,null,null);
SSLContext.setDefault(context); 
SSLSocketFactory factory = (SSLSocketFactory)context.getSocketFactory();
SSLSocket socket = (SSLSocket)factory.createSocket();
protocols = socket.getEnabledProtocols();

在应用程序中运行此程序后，TLS 1.2启用。我不想运行此程序，但我想在应用程序启动期间直接启用它。有没有办法做到这一点？

After running this program within the app the TLS 1.2 gets enabled. I do not want to run this program but I want to directly enable it during app startup. Is there any way to do it?

推荐答案

您可以将Java 7版本升级到1.7.0_131-b31

You can upgrade your Java 7 version to 1.7.0_131-b31

对于Oracle网站中的JRE 1.7.0_131-b31：

For JRE 1.7.0_131-b31 in Oracle site :

TLSv1.2和TLSv1。现在，默认情况下，在TLS客户端
端点上启用1。这与JDK 8
版本中已经发生的行为类似。

TLSv1.2 and TLSv1.1 are now enabled by default on the TLS client end-points. This is similar behavior to what already happens in JDK 8 releases.
