This article mainly explains "what is the concept and orientation of JavaWeb". The content of the explanation in the article is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn "what is the concept and orientation of JavaWeb".

Web development:

Web, the meaning of the web page

Static web

The data provided by html,css to everyone will never change!

Dynamic web

The data provided by almost all websites to everyone always changes, and everyone sees different information at different times and places: Servlet (Mini Program services) / JSP, ASP, PHP

In java, the technology of dynamic web resource development is collectively called Javaweb.

Web applications: programs that can be accessed by browsers

A.html, b.html... Multiple web resources, these web resources can be accessed by the outside world and provide services to the outside world; any page or resource that can be accessed exists on a computer in a corner of the world URL these unified web resources will be placed in the same folder, web application-> Tomcat: server A web application is composed of multiple parts (static and dynamic web)

Html,css,jsjsp,servletjava Program jar package configuration File (Properties)

After the web application is written, if you want to provide access to the outside world, you need a server for unified management.

. Htm, . Html, if these things exist all the time on the server, we can read them directly.

Shortcomings of static web

The Web page cannot be updated dynamically. All users see the same page.

Broadcast pictures, click on special effects, pseudo-dynamic JavaScript (most used in actual development) VBScript

It cannot interact with the database (data cannot be persisted, users cannot interact)

The page will be dynamically displayed: "the effect of the Web page varies from person to person."

Shortcoming

There is an error in the dynamic web resource that joined the server. We need to rewrite our daemon and republish it.

Downtime maintenance

Advantages

Web pages can be updated dynamically, and all users see different pages.

It can interact with the database
