Intellj idea debug under Mac is stuck

It's not a configuration problem, it's a bug in Java8. The solution is as follows:

Modify /etc/hosts file --> sudo vim hosts

Change 127.0.0.1 localhost to -->127.0.0.1 localhost murphysdeMacBook-Pro.local

The modified file is:

#127.0.0.1      localhost
127.0.0.1       localhost      murphysdeMacBook-Pro.local
#127.0.0.1      localhost      <hostname>
255.255.255.255 broadcasthost
::1             localhost

Get local hostname command: hostname

murphysdeMacBook-Pro:etc mofei$ hostname
murphysdeMacBook-Pro.local
