Use IntelliJ IDEA to create a new web project from scratch step by step! ! ! ! ! !

The most detailed IntelliJ IDEA project web project construction! ! ! ! ! !

1. Create a web project (the most troublesome to create for the first time)

1. Make sure the software is installed

2. Double-click to open the software --> create a new project

3. The web project selection is shown in the figure, first create an empty project space to place your project, this is a difference

Equivalent to myeclipse as shown in the figure

4. Create a project name

Equivalent to myeclipse as shown in the figure

5. Click fininsh, as shown in the figure, and ask whether the project you created is displayed on this page or on a new page. This depends on your needs. Here, the new page is used to distinguish it from my previous projects. (this is a difference)

6. At this time, the settings as shown in the figure will pop up. You need to set the JDK used, which is called SDK here.

7. If it does not pop up, you can open the settings as shown below

8. Set my JDK to 1.7 here

Equivalent to the setting of myelipse as shown in the figure below

9. Template settings

Choose as shown

As shown in the figure, the establishment project type is a web project, and then a web.xml document is required

Template naming

If you click finish at this time, you will find that a web project style is generated, and you can find that there are less things in the web folder

Compare with myeclipse (IntelliJ's web is the same as myeclpse's webRoot)

Mainly, there are less two folders under WEB-INF, which are the output folders of the web project. Myeclipse automatically generates these two folders when it is created, but IntelliJ needs to set it up by itself later, these are the two of them a big difference

IntelliJ lacks the classes and lib folders, and needs to be created and then set separately, while myeclipse will be set when it is created, as shown in the figure

The position of the red circle is automatically set
