Creating a Java Spring Boot application in IntelliJ IDEA is straightforward and can be done with the following steps:
Open IntelliJ IDEA: Launch IntelliJ IDEA on your system.
Create a New Project:
Go to File > New > Project.
In the "New Project" dialog, select Spring Initializr under Project options.
Click Next.
Configure Spring Initializr:
In the "New Project" dialog, configure the Name, Group, and Artifact ID for your project.
Choose the version of Java you want to use.
In the "Dependencies" section, you can add the necessary dependencies for your project. For example, you can select Spring Web if you want to create a web application.
Click Next and then Finish to create your project.
Navigate Your Project:
Once your project is created, you'll see the directory structure in the Project window.
The main application class will typically be located in the src/main/java directory.
Write Your Application:
In the src/main/java directory, you can start writing your Spring Boot application.
The main application class will have the @SpringBootApplication annotation, and the main method will start the application.
Configure Application Properties:
Your project will have a src/main/resources/application.properties file.
Use this file to configure various settings for your application, such as server port, database connection, and more.
Run Your Application:
To run your application, right-click on the main application class (the one with the @SpringBootApplication annotation) and select Run.
Alternatively, you can use the green play button on the gutter of the file.
Monitor Application Output:
Once you run your application, you can monitor the console output for logs and information.
Test Your Application:
If you've created a web application, you can visit the configured URL in your browser to test the application.
For other types of applications, you may need to create tests in the src/test/java directory.
Creating a Java Spring Boot application in IntelliJ is a great way to start building modern Java applications quickly and efficiently. Follow these steps to get started on your project.
