For the app side, it will be a great user experience to ensure that users can automatically continue their Pre-logon operations after logging in. So it took a bit of time to think of two ways to achieve that kind of demand.This article is about the
What is 1.actionInvocation?
Actioninvocation is the caller of the action. Actioninvocation is responsible for the dispatch of a series of elements, such as interceptor, action, and result, during action execution.

In the Friday and the weekend, work to sneak in, looking at the Java cocurrent also by the way the Thread.Interrupt and Java 5 after the implementation of the Locksupport.
Before introducing, let's throw a few questions.
The relationship between Thread.Interrupt () method and Interruptedexception anomaly? is the interruptedexception exception triggered by the interrupt trigger?
Thread.Interrupt () What state of the thread will interrupt the work? RUNNING or BLOCKING?
General thread programming n

extension tool (added in 2.6.1) that allows you to create a text file containing a format for each extension you want to add. this saves a ton of time if you have to add 1000 extensions, and it provides the ability to add all the extensions in one motion.
Trixbox also has media convergence features such as recording incoming and outgoing cals, emailing voicemail to users using Postfix, and, in the latest version, an updated Core Set of Asterisk code
commands list.
ParametersDepends on commands. Some commands have no parameters. In this case, the parameters are omitted.
Example
Exten => 123,1, answer
Exten => 123,2, playback (TT-weasels)
Exten => 123,3, voicemail (44)
Exten => 123,4, hangup
This is the definition of a single extension named "123. However, when a call is scheduled to extension 123, asterisk will answer the call by itself, play a sound file named "TT-Weasels", prompt the user to
Locksupport OverviewBasic thread blocking primitives for creating locks and other synchronization classes. The underlying threading block primitives used to create locks and other synchronization classes. This is the explanation in Java doc, and the following is a framework for a first in, out (first-in-first-out) non-reentrant lock class.The above code simple implementation of the lock function, mainly using the Locksupport Park and Unpark blocking and releasing threads, Atomicboolean CAS opera

What is an interceptor?
Asynchronous operation
Example
Session Injection (Request blocker)
Timestamp (Request and response interceptors)
Request recovery (Request exception interception)
Session Recovery (response to exception blocker)
