When doing Java Web development, we often need to use the Tomcat server to run and debug our applications. Correctly configuring the Tomcat server is a very important step when developing with IntelliJ Idea. The following will introduce in detail how to correctly configure the Tomcat server in Idea.

Step 1: Download and install Tomcat
First, we need to download the latest version of Tomcat from the Tomcat official website (https://tomcat.apache.org/) and follow the official installation guide to install. After the installation is complete, please note the installation path of Tomcat, we will need it in the following steps.

Step 2: Open Idea and create a new project
Open IntelliJ Idea and click "Create New Project" to create a new Java project. Select the "Web Application" template, fill in the project name and storage path, and click "Next".

Step 3: Configure the project structure
In the project structure, we need to select the language level of the project and the module of the project. Select the appropriate language level and module and click "Next".

Step 4: Configure dependent libraries
In this step, we need to configure the necessary dependent libraries for the project. Projects that select the "Web Application" template will use Servlet and JSP dependency libraries by default. You can add other dependency libraries according to actual needs. Then click "Next".

Step 5: Configure Tomcat server
In this step, we need to configure the Tomcat server. Click the "Add Configuration" button, select "Tomcat Server" and click "Local". In the pop-up dialog box, select the installation path of the Tomcat you just installed, and then click "OK".

Step 6: Set the server port
In this step, we need to set the port of the Tomcat server. By default, the HTTP port used by Tomcat is 8080, which can be modified as needed. In the "Servers" panel on the left, find the configured Tomcat server, right-click and select "Edit Configurations", and then modify the port number in the pop-up dialog box.

Step 7: Deploy the project
In this step, we need to deploy the project to the Tomcat server. First open the "Project" view in Idea, and then drag the project files to the "WEB-INF" folder under the "External Libraries" window. Then, select the project in the "Project" panel on the left and right-click to select "Build Artifact". Select "Build" in the pop-up submenu to build the project.

Step 8: Start the server
In this step, we need to start the Tomcat server. Find the configured Tomcat server in the "Servers" panel on the left, then select and click the "Start" button to start the server.

Step 9: Test the project
In this step, we need to test the project deployed on the Tomcat server. Open the browser, enter the address of "localhost:port number/project name", and press Enter. If everything is configured correctly, you should be able to see the project's homepage.

Conclusion:

Through the above nine steps, we can correctly configure the Tomcat server in IntelliJ Idea to facilitate Java Web development and debugging. Configuring the Tomcat server is an important part of Java Web development. I hope the guide in this article can help readers smoothly carry out their development work.
