I previously used Extjs4+java spring MVC to architect a set of "Modular general function Custom Systems", which explained the design ideas in detail, but there was no implementation process. Since EXTJS5 was released and there were many new features, and I had the idea of refactoring and adding new functionality to the original system, I decided to upgrade the system and write the upgraded development process as a blog.The development of the system will be divided into two stages:

After the official release of the EXTJS5 on June 2. With a cursory look at it, Sencha recommends using Project compilation to advertise your app. The service can be generated using the Sencha App Watch command during development. Every time you create a JS class, you need CTRL + C and then enter the Sencha App Watch command again. Otherwise, the new class will no
To write time in standard format to log files. To convert time (now () to character format "YYYY-MM-DD hh: mm: SS Zzz"
Write this function, Delphi system itself also with the Conversion Function formatdatetime ('yyyy-MM-DD hh: mm: SS zzz', now ())
You can also implement this function. Considering that this is a fixed-format conversion function for further optimization.
// Actual test results
Run 1,000,000 formatdatetime () ==> 2825 Ms
Sfformatdattime () ==> 545 Ms
// YYYY-MM-DD hh: mm: SS zzzP

by configuring the system-provided config property. For those who do not understand the configuration system, here is a brief introduction.Configuring the System 101One of the core concepts of EXT JS is the concept of the configuration (config) attribute.They were part of Ext JS from the beginning, not just in Ext JS 5 (or Sencha Touch 2.x). The framework has normalized the mechanisms of these properties. Common configurations are declared like this:

Cordova is just a webview shelf that gives you the ability to invoke the native API, and in the UI he doesn't care what your page looks like, nor does it give you any UI features, so the UI also relies on jQuery Mobile, Sencha Touch, App Framework (Jqmoby), Kendoui Mobile, Adobe topcoat, JQTouch, Ionic Framework, Onsen UI , and more.1.

Third: Because the cached row of the cached variable stop in thread 1 's working memory is invalid, thread 1 reads the main memory again when the value of the variable stop is read.
Then thread 2 modifies the stop value (there are 2 operations here, of course). Modifying the value in the thread 2 working memory and then writing the modified value to memory invalidates the cached row of the cached variable stop in the w
before writing the volatile variable).Thread A writes a volatile variable, and then thread B reads the volatile variable, which essentially is thread a sending a message to thread B through main memory.
Does 5.volatile guarantee atomic sex?
Knowing from above that the volatile keyword guarantees the visibility of the operation, but does volatile guarantee that the operation of the variable is atomic?

In fact, the development concept of ADODB is not the first. DBI appeared earlier than ADODB. It provides Perl to access the database and uses consistent API call interfaces. I believe that friends who have used Perl + DBI will have a similar feeling when they use ADODB
