Creating a Spring Boot Application in IntelliJ Community

Introduction

Spring Boot is a popular Java framework for building web applications quickly and efficiently. IntelliJ IDEA is a powerful integrated development environment (IDE) that supports Spring Boot development. In this article, we will explore how to create a Spring Boot application in IntelliJ Community.

Step 1: Setting up IntelliJ IDEA

Before we begin, make sure you have IntelliJ IDEA installed on your machine. If you don’t have it installed, you can download it from the official JetBrains website.

Setting up the Project Structure

To create a new Spring Boot project in IntelliJ IDEA, follow these steps:

Open IntelliJ IDEA and create a new project by clicking on "File" > "New" > "Project"

Choose "Spring Starter Web" under the "Spring" section

Select "Web" as the project type

Choose "Spring Boot 2.x" as the project version

Click "Next" to create the project structure

Step 2: Creating the Project

Once the project is created, you can start building your application. Here’s a step-by-step guide:

Create a new Java class by right-clicking on the project and selecting "New" > "Java Class"

Name the class "HelloWorldApplication"

Add the following code to the class:



import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class HelloWorldApplication {
public static void main(String[] args) {
SpringApplication.run(HelloWorldApplication.class, args);
}
}

*   This code creates a simple Spring Boot application that runs the `HelloWorldApplication` class.



**Step 3: Configuring the Application**



To configure the application, you need to add the following dependencies to your `pom.xml` file (if you're using Maven) or your `build.gradle` file (if you're using Gradle):



*   Add the following dependency to your `pom.xml` file:

```xml

<dependency>

    <groupId>org.springframework.boot</groupId>

    <artifactId>spring-boot-starter-web</artifactId>

</dependency>

Add the following dependency to your build.gradle file:

dependencies {

implementation 'org.springframework.boot:spring-boot-starter-web'

}

Step 4: Running the Application

To run the application, you need to execute the following command:

Open a terminal or command prompt and navigate to the project directory

Run the following command:
```
mvn spring-boot:run
```

Alternatively, you can run the application using the following command:
```
gradle bootRun
```
Step 5: Testing the Application

To test the application, you can use the following tools:

Use the following command to test the application:
```
curl http://localhost:8080/hello
```

This command sends a GET request to the root URL of the application and prints the response to the console.

Step 6: Deploying the Application

To deploy the application, you need to create a deployment plan. Here’s how to do it:

Create a new deployment plan by right-clicking on the project and selecting "New" > "Deployment Plan"

Choose "Spring Boot" as the deployment type

Select "Web" as the deployment type

Choose "Spring Boot 2.x" as the deployment version

Click "Next" to create the deployment plan

Step 7: Monitoring the Application

To monitor the application, you can use the following tools:

Use the following command to get the application’s status:
```
curl http://localhost:8080/status
```

This command sends a GET request to the root URL of the application and prints the response to the console.

Conclusion

Creating a Spring Boot application in IntelliJ IDEA is a straightforward process that requires minimal setup. By following these steps, you can create a simple Spring Boot application that runs on your local machine. With this article, you now know how to create a Spring Boot application in IntelliJ IDEA.
