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，并且身份验证正常工作，但在尝试执行查询时立即断开连接。有谁见过这个问题？

Answer 1

Oracle为已知会干扰Microsoft JDBC / jTDS连接的SSL / TLS BEAST攻击引入了一个安全修复程序。

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

此SO主题中的信息：Java7 sqljdbc4 - SQL error 08S01 on getConnection()

Answer 2

通过将ssl=request或ssl=require添加到连接字符串的URL，我能够解决相同的基本错误。这会尝试或要求加密连接。如果SQL Server设置为要求加密连接，则ssl = require将强制连接使用SSL并且将满足SQL Server。

示例：

JDBC：JTDS：SQLSERVER：// [SERVER] / [数据库]; SSL =需要;

SSL身份验证后，JDBC（JTDS）SQL Server连接已关闭
