How to Use a Spring Boot Application as a Dependency in Your Project?

What steps should I follow to integrate a Spring Boot application as a dependency in my project?

<dependency>
    <groupId>com.example</groupId>
    <artifactId>my-spring-boot-app</artifactId>
    <version>1.0.0</version>
</dependency>

Integrating a Spring Boot application as a dependency allows for code reuse and modularity. This tutorial outlines the steps required for effective integration, configuration options, and highlights potential pitfalls.

<dependency>
    <groupId>com.example</groupId>
    <artifactId>my-spring-boot-app</artifactId>
    <version>1.0.0</version>
</dependency>

// Gradle example
implementation 'com.example:my-spring-boot-app:1.0.0'

Causes

• Incorrect groupId, artifactId, or version specifications.
• Missing dependencies in the main application that are required by the Spring Boot application.
• Configuration issues in the Spring Boot application that lead to classloader problems.

Solutions

• Ensure that the groupId, artifactId, and version match those specified in the Spring Boot application's `pom.xml` or `build.gradle`.
• Include all necessary dependencies in the main project's configuration files.
• Verify that the Spring Boot application is correctly packaged as a JAR and is accessible in the local or remote Maven repository.

Mistake: Forgetting to include the dependency in the build configuration file.

Solution: Make sure to add the Spring Boot application as a dependency in your `pom.xml` (Maven) or `build.gradle` (Gradle).

Mistake: Using an improper version of the Spring Boot application.

Solution: Check the version compatibility between your main application and the Spring Boot dependency.

Mistake: Assuming the dependency will automatically include its transitive dependencies.

Solution: Manually declare necessary transitive dependencies in your project if they are not automatically included.
