我正在使用 jTDS JDBC SQLServer 库连接到 SQL Server 2008 数据库。它总是在没有 SSL 的情况下工作，但是一旦我们启用它，我就无法连接它。我已经跟踪了如下所示的 Java 并检查了数据库端的日志，并且身份验证工作正常，但在尝试执行查询时立即断开连接。有人见过这个问题吗？

ssl=request通过添加或ssl=require连接字符串的 URL，我能够绕过相同的基本错误。这要么尝试要么要求加密连接。如果 SQL Server 设置为需要加密连接，则 ssl=require 将强制连接使用 SSL 并满足 SQL Server。

例子：

jdbc:jtds:sqlserver://[SERVER]/[DATABASE];ssl=require;

Oracle 为已知会干扰 Microsoft JDBC/jTDS 连接的 SSL/TLS BEAST 攻击引入了安全修复程序。

设置-Djsse.enableCBCProtection=false系统变量将禁用修复并可能允许连接。
