由于SSLException,无法连接到SQLServer

Question

从昨天开始,我无法从JBoss EAP 6.2连接到本地开发机器上的MicroSoft SQLServer(v11.1.3000.0).SQLServer现在想要使用SSL进行连接.

我得到以下异常:

Caused by: com.microsoft.sqlserver.jdbc.SQLServerException: The driver could not establish a secure connection to SQL Server by using Secure Sockets Layer (SSL) encryption. Error: "java.lang.RuntimeException: Could not generate DH keypair". ClientConnectionId:da0dbbf4-33a0-45ac-9885-fa1e31c47c6e

当我在测试环境中连接到SQLServer(11.0.2100.60)时,一切正常.

我已经完成了以下工作: - 确保我的Java 6 JRE中有正确的JCE库 - 更新了sqljdbc4.jar - 阅读:Java:为什么SSL握手会提供"无法生成DH密钥对"的异常？

我没有尝试过上面的文章中的解决方法.我宁愿阻止SQLServer驱逐SSL.

如何阻止SQLServer要求SSL连接？或者修复我的配置？这怎么可能发生呢？是否有SQLServer的自动更新？

今天早上我遇到了同样的问题,一些单元测试开始失败.我注意到我正在使用1.6 JDK编译项目,将其更改为1.7.0_79使问题消失.

不知道问题的根本原因是什么,没有时间进一步调查.
