解决com.microsoft.sqlserver.jdbc.SQLServerException: 驱动程序无法通过使用安全套接字层(SSL)加密与 SQL Server 建立安全连接。错误

运行环境：

• java1.8
• sqlserver 2008
• 连接驱动：mssql-jdbc：8.4.0.jre8
• 连接池druid
• 持久层框架mybatis
• Windows10

错误信息

在项目启动加载连接池时没有错误，调用接口执行SQL时抛出以下错误：

解决方案

在Java的安装目录的\jre\lib\security下，打开并编辑java.security文件，我本地是C:\Program Files\Java\jdk1.8.0_241\jre\lib\security\java.security。

打开文件后，修改jdk.tls.disabledAlgorithms这一项，去掉3DES_EDE_CBC,字符。然后重新启动项目，调用数据库执行SQL就没问题了
