method, and a lot of work is done here. ASP. net mvc contains several types ending with a Descriptor. First, the ControllerDescriptor is obtained. This is relatively simple. The actual returned type is the ReflectedControllerDescriptor object. The second step is to call the FindAction method of ReflectedControllerDescriptor to obtain ActionDescriptor. The most important attribute of ActionDescriptor is MethodInfo, which is the method of action corres

1. MVC Design PatternModel 1 Architecture mode (basically no use)The core of model 1 is the JSP file, and the project developed using Model 1 contains a large number of independent JSP files and a small subset of JavaBean. When developing with model 1, the JSP is responsible for receiving form parameters, processing business logic, and ultimately returning the results to the client's browser side.The program flow of Model 1 is relatively easy to under

First look at the MVC pattern flowchart (in fact, the MVC design pattern is model2 in Java .) : As shown in the figure, the C layer mainly controls page jumps at the servlet layer. The m layer is the specific service processing logic, and the JSP layer is the so-called v layer. MVC is different from what we call three layers. We usually call three layers as t

Brief introduction:People who have studied basic Java Web Development have learned how to write a basic servlet, how to write a JSP, and how to update the content displayed in the browser. But we've written our own applications in general there is no reason, for a small web site such writing no problem, but we need to write large Web projects, our existing writing mode will cause the Web application scalability is poor, And one problem cannot pinpoint where the problem is.Java is a language with

The original use of JSP development program, because a lot of things written in confusion, the project is big or change when it will be very difficult, linkage is too large, sometimes modify the view of things can affect business logic, stratification is not clear.Later heard of Struts MVC, did a few examples, the level is clear, each actionbean or interceptor have to configure the mapping, configuration to get to the trouble, of course, with the conf

MVC is an ideal way to construct a software or component from 3 different parts:1. Model: The object used to store the data.2. View: The object that provides the data display for the model.Controller: Responsible for the specific business logic operation, that is, the controller according to the requirements of the view of the data processing, and the results stored in theModel, it is also the responsibility to have the model and view interact as nece

To better demonstrate the way MVC works, we use a simple newsArticleThe publishing system can be used as an example in two ways: MVC and MVC.We will only give a basic demonstration, read some article lists from the database, and display them on the page. The general process is to connect to the database, query the database, and output HTML results cyclically. The followingCodeThat's what we do. (Fresh water

Summarize the recently learned MVC content according to your own understanding. I hope you can give some advice on the mistakes. Principle of MVC The process is: URL (the address entered by the user)-> routes (route address processing to find the correct address)-> controllers (controller, the internal methods correspond to pages with the same name. These methods are collectively referred to as action)-> m

The following is an excerpt from ASP. NET mvc3 advanced programming.

TempData is used to transfer some temporary data, such as passing temporary data between controller actions or passing some temporary data to the view, I believe everyone has seen "What are the methods of passing values between ASP." This interview question, TempData is one of the methods of passing values in ASP. TempData By default is to use the session to store temporary data, the data stored in the TempData

Reprint Address: http://www.cnblogs.com/QLeelulu/archive/2008/10/05/1303991.html asp.net MVC provides a number of Hellper methods, Hellper is a way to generate HTML code that makes it easier for us to write HTML code (some friends prefer to write HTML code directly). We can also use the. NET 3.5 extension method to write our own hellper. For example: The generated HTML code is: I will not elaborate on the use of the various methods of hellper, and
