java - JDBC (JTDS) SQL Server 连接在 SSL 身份验证后关闭

Question

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 Java，如下所示，并检查了数据库端的日志，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？

Oracle 引入了针对已知会干扰 Microsoft JDBC/jTDS 连接的 SSL/TLS BEAST 攻击的安全修复程序。

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