NetworkManager 0:off 1:off 2:off 3:off 4:off 5:off 6:off
After stopping the NetworkManager service we can use IP alias technology to configure multiple IP addresses, here we use the IP command, the command syntax format is as follows:
IP addr Add 172.25.215.40/24 dev Etho label eth0:0
Behind the eth0:0 says, we add an IP alias to eth0 this network card, the latter 0 means a name, the second alias
There is no coding task recently, as a small spicy chicken to graduate, the task is to look at the company's new system, familiar with how to use what is what.I drank two cups of water in the afternoon and felt a little wave. Then I started to look at the code. It is found that a function is such a child. var TX = {};//namespace function tx.namespace = function (str) {var arr = Str.split ("."); var o =
"));

After reading the questions for a long time, I thought there was a profound method. I didn't expect the last Brute Force pruning to be completed.

default value is false.
9. diskexpiryintervalseconds: Specifies the polling time of the listener thread dedicated to clearing expired objects.
Example:
1. Fetch data from the second-level cache
// Test the second-level cache
/*
* After the session is closedHibernateAnd then query the same data,
* Will certainly be issuedSQLHowever, if the current object is cached in the second-level cache, the session is closed,
* The second-level cache does not disappear, and the same data will be queried at
, the console prints the insert statement, but the database does not have data
Tx. commit (); Submit the transaction
Session. close (); execute to this, only data in the database is available. Refresh the database and you can see
System. out. println (p );
}2. query entities based on the Union primary key

Nice, we had implement Ethereum account generation. As we know, from mnemonic with path, a specify account can be recovery; With KeyStore and passphrse, we can recovery account to, safe them seperate!
