IntelliJ IDEA如何在Gradle项目中支持Web Application

总结步骤如下：

1、项目结构如下：

project

|——web

             |———WEB-INF

                                  |————web.xml

             |————index.jsp

2、配置一个Web Application:Exploded或者Web Application:Archive类型的artifact

3、根据static Web content resources配置web Facet

4、详细方法可以自行参照帮助文档中的Web Applications下的文件说明

以下是软件帮助中的方法介绍：

Enabling Web Application Support

Some features described here are available in Ultimate edition only.

The dedicated Web facet provides facilities for developing Web applications, sets up the relevant module structure, and creates the required deployment descriptors. You can create anew module with a dedicated Web Application facet from scratch or add a facet to anexisting module.

IntelliJ IDEA configures the module as follows:

• Creates the structure of the module with the web andWEB-INF nodes.
• Creates a Web application deployment descriptor web.xml under theWEB-INF node .

  This is done automatically for versions 2.2 - 2.5.

• Creates an index.jsp file that will be the home page of your application and stores it below theweb node.
• Configures a basic artifact of the typeexploded with the following structure:

  You can use this configuration as is or customize it, as required, for example, includestatic Web content resources.

To enable web development support in a new module

1. Create a Java module from scratch.

   On the first page of the wizard, select Java Module, notWeb Module. (The Web module type is for developing web applications using programming languages other than Java, for example,PHP, or JavaScript, ormarkup languages.)

2. On the fourth, Select the desired technologies, page of the wizard, select theWeb Application check box.
3. From the Version drop-down list, select the relevant specification. The available options are:
   • 2.2 - 2.5 - if you choose one of these options, IntelliJ IDEA will create a Web application deployment descriptor for you automatically.
   • 3.0 - if you choose this option, select the Create web.xml check box to have a Web application deployment descriptor created. Clear the check box to use annotations instead.

To configure web development support in an existing module

1. Add a Web facet to the module andopen its settings. The right-hand pane shows theWeb Facet settings.
2. The Deployment Descriptors area shows the location of theweb.xml deployment descriptor, which is already created for you. To change its location or version, click  (Enter).
3. To assign another existing descriptor, click  (Alt+Delete) and confirm deletion in theDelete Deployment Descriptor dialog box that opens. To have the current descriptor removed from your computer, select theAlso delete file from disk check box and clickYes. In theDeployment Descriptors area, where IntelliJ IDEA returns you, click  (Alt+Insert) and select the desired version and file in theDeployment Descriptor Location dialog box that opens.
4. If your application server needs a proprietary deployment descriptor, click theAdd Application Server Specific Descriptor button and select your server from the list.

No matter whether you are creating a module from scratch or adding a Web facet to an existing module, IntelliJ IDEA detects conflicts and suggests to resolve them.

• If some required libraries are missing, click the Fix button. The necessary libraries will be downloaded and installed automatically.
• If the facet resources are not included in any of the previously configured artifacts, click the Fix button and choose the appropriate artifact from the list.
• If no artifacts of the relevant type are configured, click the Create Artifact button and configure the artifact layout on the Artifacts page of the Project Structure dialog box that opens.
