How to build a SpringBoot project

Steps to build SpringBoot project: 1. Make sure that JDK, Maven, IDE and other tools have been installed; 2. Use Maven to create a new Spring Boot project; 3. In the Spring Boot project, you can add dependencies Introduce the required functional modules; 4. Write a Spring Boot application; 5. Run the Spring Boot project; 6. After completing development and testing, deploy the Spring Boot project to the production environment.

Spring Boot is a framework for building standalone, production-grade Spring applications. It simplifies the development process of Spring applications and provides automatic configuration, rapid development and deployment features. In this article, I will introduce in detail the steps to build a Spring Boot project.

1. Preparation

Before starting to build the Spring Boot project, you need to ensure that the following tools have been installed and configured:

1. JDK: Make sure it has been installed Java Development Kit (JDK), and the JAVA_HOME environment variable is configured.

2. Maven: Make sure Maven is installed and the MAVEN_HOME environment variable is configured.

3. IDE: You can choose to use integrated development environments such as Eclipse and IntelliJ IDEA.

2. Create a project

The following are the steps to use Maven to create a new Spring Boot project:

1. Open the command line tool and enter the directory where you want to create the project .

2. Run the following command to create a new Maven project:

mvn archetype:generate -DgroupId=com.example -DartifactId=demo -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false

This command will create a basic Maven project using Maven's archetype plugin.

3. Enter the newly created project directory:

cd demo

3. Add dependencies

In the Spring Boot project, you can introduce the required functional modules by adding dependencies . The following are the steps to add common dependencies:

1. Open the project's pom.xml file.

2. Add the required dependencies in the tag. For example, if you want to use the Spring Web module, you can add the following dependency:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>

This dependency will introduce all the dependencies required by the Spring Web module.

3. Save the pom.xml file and Maven will automatically download the required dependencies.

4. Writing code

In the Spring Boot project, the main business logic code is located in the Java class. The following are the steps to write a simple Spring Boot application:

1. Create a new Java class in the src/main/java directory.

2. Add the @SpringBootApplication annotation to the class. This annotation is used to mark the class as the entry point of a Spring Boot application. For example:

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

3. Add other business logic code. You can add controller, service, data access object and other code in this class.

5. Run the project

After completing the code writing, you can use the following steps to run the Spring Boot project:

1. Open the command line tool and enter the root of the project Table of contents.

2. Run the following command to start the application:

mvn spring-boot:run

This command will use the Maven plug-in to start the Spring Boot application.

3. Open the browser and visit http://localhost:8080 (default port) to view the application running results.

6. Deployment Project

After completing development and testing, you can use the following steps to deploy the Spring Boot project to the production environment:

1. Package the application. Run the following command to generate an executable JAR file:

mvn package

This command will generate a JAR file in the target directory of the project.

2. Upload the JAR file to the server.

3. Run the JAR file on the server. Run the following command to start the application:

java -jar demo.jar

This command will use the Java virtual machine to run the JAR file.

4. Use a browser to access the IP address or domain name of the server to view the deployed applications.

Summary

This article details the steps to build the Spring Boot project. By creating a project, adding dependencies, writing code, running the project, and deploying the project, you can quickly build and develop Spring Boot applications. Spring Boot provides rich functions and simplified development processes, allowing developers to focus more on the implementation of business logic. Hope this article helps you!
