Setup Spring Boot in Eclipse

Setting up a Spring Boot project in Eclipse involves several steps, including installing Eclipse, configuring the Eclipse IDE, and creating a new Spring Boot project. Below is a detailed illustration of how to set up a Spring Boot project in Eclipse:

Prerequisites

1. Java Development Kit (JDK): - Ensure that you have the latest version of JDK installed on your machine. You can download it from the [official Oracle website](https://www.oracle.com/java/technologies/javase-downloads.html) or use OpenJDK.
2. Eclipse IDE: - Download and install Eclipse IDE for Java EE Developers from the [Eclipse Downloads page](https://www.eclipse.org/downloads/).

Steps to Set Up Spring Boot in Eclipse

Step 1: Install Spring Tools for Eclipse (STS) Plugin

1. Open Eclipse IDE. Go to `Help` -> `Eclipse Marketplace`. 
2. In the Eclipse Marketplace dialog, search for "Spring Tools" in the "Find" field. 
3. Install "Spring Tools 4 - for Spring Boot (aka Spring Tools 4)". 
4. Follow the on-screen instructions to complete the installation. Restart Eclipse if prompted.

Step 2: Create a New Spring Boot Project

1. In Eclipse, go to `File` -> `New` -> `Other...`. 
2. In the "Select a wizard" dialog, expand the "Spring Boot" folder and select "Spring Starter Project". 
3. Click "Next".

Step 3: Configure the Spring Boot Project

1. Enter a name for your project in the "Name" field. 
2. Choose a location to save your project. 
3. Select the desired options for "Group" and "Artifact". 
4. Choose your desired version of Spring Boot. 
5. Select the desired packaging (e.g., JAR or WAR). 
6. Add the necessary dependencies based on your project requirements (e.g., Spring Web, Spring Data JPA). 
7. Click "Finish".

Step 4: Explore the Spring Boot Project

1. Eclipse will generate the project structure and download the required dependencies. 
2. Once the project is created, you will find a file named `Application.java` in the `src/main/java` folder. This file contains the main method to run the Spring Boot application. 
3. You can start your Spring Boot application by right-clicking on `Application.java` and selecting `Run As` -> `Spring Boot App`.

Step 5: Verify the Spring Boot Application

1. Open a web browser and navigate to `http://localhost:8080`. You should see the default Spring Boot welcome page. 
2. The console in Eclipse will display logs indicating that the application has started.

You can now start developing your Spring Boot application based on your project requirements.
