Spring Boot: Managing Dependencies with Maven

Share:

Web DevelopmentJava

Hi everyone,
I’m working on a Spring Boot project and I’m having trouble managing dependencies using Maven. Can someone explain how to properly configure the pom.xml file and manage dependencies in a Spring Boot application? Are there any common pitfalls to avoid?

Hi,
To manage dependencies in a Spring Boot project using Maven:

  1. Create a Maven Project: Use Spring Initializr or create a pom.xml manually.
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <groupId>com.example</groupId>
    <artifactId>demo</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.5.2</version>
    </parent>
    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-jpa</artifactId>
        </dependency>
        <dependency>
            <groupId>com.h2database</groupId>
            <artifactId>h2</artifactId>
            <scope>runtime</scope>
        </dependency>
    </dependencies>
</project>
  1. Add Dependencies: Add the necessary dependencies to your pom.xml.
<dependencies>
    <!-- Spring Web Starter -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <!-- Spring Data JPA Starter -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-jpa</artifactId>
    </dependency>
    <!-- H2 Database -->
    <dependency>
        <groupId>com.h2database</groupId>
        <artifactId>h2</artifactId>
        <scope>runtime</scope>
    </dependency>
</dependencies>
  1. Manage Dependency Versions: Use properties to manage versions centrally.
<properties>
    <java.version>11</java.version>
    <spring-boot.version>2.5.2</spring-boot.version>
</properties>
  1. Build and Run: Use Maven commands to build and run your project.
mvn clean install
mvn spring-boot:run

Managing dependencies with Maven in a Spring Boot project ensures all necessary libraries are included and versions are consistent.
