How does Spring Boot resolve dependency conflicts?

Dependency conflict refers to conflicts that arise when different versions of dependencies are introduced while using Spring Boot, causing the program to fail to run properly or generating exceptions. The methods to resolve dependency conflicts are as follows:

1. Update dependency versions: If dependency conflicts are caused by using outdated versions, try updating dependencies to the latest stable version.
2. Exclude conflicting dependencies: Utilize the exclude dependencies feature of build tools such as Maven or Gradle to remove conflicting dependencies, and then manually introduce the correct dependencies.
3. Introducing a uniform version for conflicting dependencies: If conflicting dependencies have updated versions, consider introducing a unified version to resolve the conflict.
4. Manage dependencies using dependencyManagement: using the dependencyManagement tag in the parent project’s pom.xml file to control the versions of dependencies, ensuring consistency across all sub-projects and avoiding conflicts.
5. You can check the dependency tree of a project by using the “mvn dependency:tree” command. This helps identify all dependencies in the project, allowing you to resolve any conflicts that may arise.
6. Specify a higher priority version of the dependency: Specify a higher priority version of the dependency in the pom.xml file using the or tags to resolve conflicts.
7. By utilizing the dependency management provided by Spring Boot, you can use the tag to centralize and avoid conflicts in managing dependencies effectively.

In conclusion, resolving dependency conflicts requires careful analysis and handling, selecting the appropriate solution based on the specific circumstances.
