Sql server Can'；t将Debezium 0.9.2连接到SQL Server 2008 R2

当我尝试在启用CDC功能后将Debezium连接到SQL Server数据库时，出现以下错误消息：

我在这里找到了一个解决方法：

但有可能将其应用于debezium连接器上吗？Debezium是否与Sql Server 2008 R2兼容，因为它在文档中写道：

The functionality of the connector is based upon change data capture feature provided by SQL Server Standard (since SQL Server 2016 SP1) or Enterprise edition

作为参考，我使用了Debezium Docker Images 0.9.2： -debezium/动物园管理员 -德贝齐姆/卡夫卡 -解压/连接

提前感谢你的帮助

当我激活TLS调试模式时，我发现了这个问题

因此，我看到Java8默认使用TLSV1.2，即使我在JDBC连接属性中设置了任何TLS选项

当我尝试用Java7连接到SQLServer时，它成功了。 经过一些搜索，我发现这是因为Java7使用了这个TLS算法：3DES\U EDE\U CBC

解决方法是将值

3DES\u EDE\u CBC

删除到

jdk.tls.disabledAlgorithms

键中的java.security文件中

现在Debezium可以连接到我的Sql Server了

别担心，我不是在使用生产平台；-）

您好，Debezium从未使用SQL Server 2008进行过测试。我建议您尝试

authentication

JDBC连接属性中的

NotSpecified

值，因为它应该绕过SSL并验证Debezium是否有效。只有在这之后，在安全层上工作才有意义。感谢您的响应，但是我如何将authentication=NotSpecified设置到JDBC连接中呢？我尝试将“database.authentication”：“NotSpecified”和“database.history.authentication”：“NotSpecified”放入连接器配置中，但我得到了相同的结果=>原因是：com.microsoft.sqlserver.jdbc.SQLServerException:驱动程序无法使用安全套接字层（SSL）加密建立到SQL Server的安全连接。错误：“SQL Server未返回响应。连接已关闭
