Spring Boot Controller
In the previous article, we have created a HellController in the HelloWorld program, which contains the JSON response method. This article will explain it to the Controller.
In the previous article, we used the @ RestController annotation in the Controller, which was introduced by Spring 4.0. View the source code to see that it contains the

Here we compare the pros and cons of the two methods
The filter definition process is more complex and less efficient, but it can filter each action separately, the same action can have more than one filter information, the use of more flexible.

3. Interrupt Controller Driver
In the Linux kernel, individual device drivers can simply invoke Request_irq (), ENABLE_IRQ (), DISABLE_IRQ (), local_irq_disable (), local_irq_enable () such as General API complete interrupt application, enable, prohibit and so on function. When porting Linux to a new SOC, the chip vendor needs to provide low-level support for that part of the API.

in ASP. NET MVC, the data is often passed between the controller and the view, so it is important to master the data transfer method between the two layers skillfully and flexibly. This paper discusses from two aspects:Ø Controller transmits data to ViewØ View transmits data to ControllerFirst, Controller to View Passing Data1. Passing Data using ViewData We defi

Use the T4 template to generate the constructors and parameters of the ASP. NET Core controller, t4corePreface
In ASP.. NET Core introduces DI, and through the constructor injection parameters, the Controller will inject a large number of configuration parameters using DI. If there are many configuration injection parameters, in addition, if the configuration parameters required by each
rotated, or when the application starts east, in order to tell the user to rotate the device to display the view correctly. This is very common, because the interface is specially designed, and the screen is not square, so in fact, only a specific mode (landscape screen or landscape screen) can be displayed ). To support rotation, the view controller needs to rewrite shouldAutorotateToInterfaceOrientation:
->load->view (' Blogview ', $data);
}
}
Get view content (assign to a variable)
$buffer = $this->load->view (' Blogview ', $data, true);
The third optional parameter of the view function can change the behavior of the function. If you set the view third argument to True (Boolean), the function returns data. The default behavior of the view function is false, which sends data to the browser. If you want to return da

Introduction to MVC :MVC begins in the desktop program, M refers to the business model, v refers to the user interface ,C is the controller, the purpose of using MVC is to separate m and v implementation code, so that the same program can use different representations. MVC is a pattern of creating WEB applications using MVC (Model View Controller-View-controller)
combination.
As a description, you can also define the Controller object in a separate JS file and put the HTML page in the file.
You can use ng-model or the following expression to use studentController attributes.
Enter first name:
There are two input boxes: student. firstName and student. lastname.
Now the student. fullName () method is added to HTML.
Now, you only need to enter what is in the first name and lastname input boxes, you can see that

NET MVC, a class that implements the IController interface directly or indirectly is considered a controller by the MVC framework.using System.Web.Routing; namespace system.web.mvc{ publicinterface icontroller { void Execute (RequestContext requestcontext);} }From the code, see that this interface has a unique method of execute, which is

You can now use the Studentcontroller student's properties using Ng-model or using an expression as follows.
Enter Name:
Now there are student.firstname and student.lastname two input boxes.
There are now student.fullname () methods added to HTML.
Now, as soon as you enter what is entered in the first name and LastName input box, you can see two names
machine snapshot rollback of domain controllers also required the cloning and recovery process:
The cloned source Windows Server 2012 runs on the guest virtual machine
Virtualization Host Platform hypervisor layer support vm-generation ID (Vmgid)
Note the above requirements that domain controller virtual machine clones are not equivalent to snapshot recovery for domain
controllers.
After the above scenario is completed, let's take a look at how to implement it.
