    • Benefits: Refer to IntelliJ idea 14 to create a MAVEN project two (this article describes the benefits of creating a MAVEN project in this way) and IDEA14 to create a Web project using MAVEN (this article describes the drawbacks of creating Maven with templates.) ）
Create a new MAVEN project
    • New A project

    • Do not select any Maven templates

    • Play a GroupID, Arifactid

    • A project name. Note: Idea_project is the working interval for this project, MAVENDEMO_IDEA15 is the subdirectory where this item is stored.

    • After building the project, open, click Auto-import

    • The following structure for this project

Project deployment
    • Click

Project: No setup required (of course, click Project complier output to customize the compilation directory)

Modules: you can see that this project does not have any adaptation service components (because Maven was created manually, no Maven templates were selected)-so we need to add them.

    • Select Web (Add Web service component for this project, this is a Web project)

    • Now set the resource directory for the Web. Double-click Web Resource Directory

    • Select Scr/main Directory

    • Add WebApp at the back. Well, the Ok,web resource directory is set up.

    • Now set the directory for the Web description file

    • Set in the WebApp directory

Aftifacts:This aftifacts describes the current project release information. Now add and select from Modeles.

Description: A: Now artifacts has a published project (the ideais exactly modele) B: TheOutput root directory Describes the current project's compilation directory and adaptation service.

Determine the structure of the current project after:

    • If necessary, add Lib package

Deploying servers

    • Add Server

    • Deployment

Note: Many children's shoes cannot be found here arifact, please refer to the configuration of modules in the deployment project. If the Web service component is not configured for the project, then there is no artifact. (The current project is not even a Web project, where is the artifact, and what is deployed?) ）

    • Note the following selections:

Writing code tests
    • Create a Java class. There's a problem with inheritance HttpServlet--it's because you didn't add Tomcat dependencies to the module
