Creating a Spring Boot Project

To build microservices with Spring Boot, we first need to set up a new Spring Boot project and configure the necessary dependencies. In this section, we will walk through the steps to create a Spring Boot project.

Step 1: Prerequisites

Before we begin, make sure you have the following prerequisites:

• Java Development Kit (JDK) installed
• Spring Boot CLI installed

Step 2: Create a new Spring Boot project

To create a new Spring Boot project, open your terminal and run the following command:

1$ spring init --name=myproject --groupId=com.example --dependencies=web myproject

In the command above, replace myproject with the desired name for your project. The --groupId option specifies the project's group ID and --dependencies option specifies the required dependencies. In this example, we are using the web dependency to include the Spring Web module.

Step 3: Configure project dependencies

Next, navigate into the project folder using the cd command:

1$ cd myproject

Open the pom.xml file in a text editor and add any additional dependencies your project requires. For example, if you need to include the Spring Data JPA module, add the following code snippet inside the <dependencies> tag:

1<dependency>
2    <groupId>org.springframework.boot</groupId>
3    <artifactId>spring-boot-starter-data-jpa</artifactId>
4</dependency>

Save the pom.xml file after making the necessary changes.

Step 4: Build and run the project

To build the project, run the following command:

1$ mvn clean install

Once the project is successfully built, you can run it using the following command:

1$ java -jar target/myproject.jar

Congratulations! You have successfully created a Spring Boot project. In the upcoming lessons, we will explore how to build microservices and implement various features using Spring Boot.
