As developers, we often need to build a server locally. Run and test our web application. Tomcat is a very popular web server that supports Java Servlet and JSP technology.

This article will provide a concise guide to teach you how to use Idea to configure Tomcat and build a local Web server from scratch.

1. Download and install Tomcat

First, you need to download the Tomcat installation package from the official Apache website. Please make sure to download the latest version and choose the installation package suitable for your operating system.

After the download is complete, follow the Tomcat installation guide to install it. If you are a Windows user, you can choose to install Tomcat in a custom directory, such as "D: omcat".

1. Open Idea, click "File" -> "Settings" in the menu bar, find "Build, Execution, Deployment" -> "Application Servers" ".
2. In the window on the right, click the " " button and select "Tomcat Server".
3. In the pop-up window, select "Local" and click "Next".
4. In "Application server directory", select the Tomcat installation directory. If you installed Tomcat in "D: omcat", enter that path.
5. In "Tomcat Home", select the root directory of Tomcat. If you installed Tomcat in "D: omcat", enter "D: omcat".
6. In "Server ports", select the settings that suit you. By default, the HTTP port is 8080 and the HTTPS port is 8443.
7. Click "Next", then click "Finish".
8. After completing the above steps, you will return to the "Settings" window. Click "OK" to save the configuration.

3. Create a new Web project

1. In Idea, click "File" -> "New" -> "Project" and select "Java " -> "Web Application".
2. Enter the project name and save path, and click "Next".
3. In "Web Application Technologies", select "Java EE" and click "Next".
4. In "Additional Libraries and Frameworks", select "Web" and click "Next".
5. In "Server", select the Tomcat server you just configured, and then click "Finish".

4. Write and run code

1. In the project structure, find the "src" directory, right-click it, and select "New" -> "Package". Give a suitable package name, such as "com.example", and click "OK".
2. In the package you just created, right-click it and select "New" -> "Servlet". Give a suitable class name, such as "HelloWorldServlet", and click "OK".
