数据库的恢复（恢复数据库的时候，不能出现同名的数据库，有的话需要删除）
mongorestore -h dbhost:port -d dbname dbdirectory --dropdbnam恢复的数据库之后的名称，dbdirectory恢复数据库所在的目录
带上参数drop的意思，如果存在相同的数据库，删除重新建立。
D:\Program Files\MongoDB\Server\4.0\bin>mongorestore.exe -h localhost:27001 -d mldn D:\dump\mldn --drop
2018-09-10T10:10:55.065+0800 the --db and --collection args should only be used when restoring from a BSON file. Other uses are deprecated and will not exist in the future; use --nsInclude instead
