其实解决方法很简单，只需要加上一个字段就行了，只要是关于套接字连接错误的都可以这样解决，而且不用修改SQL server管理器的配置
trustServerCertificate=true；
trustServerCertificate=true；在不同的环境下有不同的加法，具体情况请往下看
说明：我的1433端口被占用了，所以使用的是1434端口
1.1
先看报错信息：ERROR c.a.d.p.DruidDataSource - create connection SQLException, url: jdbc:sqlserver://localhost;DatabaseName=PT_STORE_HLW, errorCode 0, state 08S01
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:“SQL Server 未返回响应。连接已关闭。 ClientConnectionId:22dc49b0-221d-4a51-9a84-8d507658df6e”。
