MAC & IDEA & SpringBoot启动慢, 提速小窍门

1、打开终端, 获取hostname

$ hostname 
appledeMacBook-Air.local

2、提权修改hosts文件

$ sudo vim /etc/hosts
##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting.  Do not change this entry.
##
127.0.0.1       localhost
255.255.255.255 broadcasthost
::1             localhost
# 这两行是新增的, hostname拿到的主机名是关键
127.0.0.1       appledeMacBook-Air.local
::1             appledeMacBook-Air.local
