nest 5.x升nest 8.x 中遇到的问题，sqlserver 链接需要ssl认证，nest7好像有警告。

解决方法：在数据库配置 options加入 trustServerCertificate:true

const dbconfig = {
  type: 'mssql',
  host: '***.***.*.***',
  database: 'testdb',
  password: '****',
  port: 1433,
  username: '**',
  logging: true,
 entities: [User, Role, Group, ClientSystem, ClientLogin, ClientAddress, SystemLog, SystemDepartment,
 SystemHospital, ClientExtendParam, ClientParams, LoginLog] ,
  synchronize: false, 
  extra:{
    trustServerCertificate:true
    }
};
