Spring Boot Graalvm Native

In this tutorial, you'll learn about Fix Spring Boot GraalVM Native Image Build Fails. We cover key concepts, practical examples, and best practices.

The Problem

GraalVM native image build fails with reflection or resource errors.

Quick Fix

Add reflection hints

Wrong:

// No reflection config

Output:

Reflective access fails

Right:

@TypeHint(types = User.class)
// Or use JSON reachability metadata

Output:

Reflective access configured

Use aot phase

Wrong:

mvn package -Pnative
// Without AOT processing

Output:

AOT not triggered

Right:

mvn -Pnative spring-boot:aot-generate

Output:

AOT processing generates hints

Configure resource hints

Wrong:

// Resources not included

Output:

Files missing in native image

Right:

// Add to resource-config.json
{ "pattern": "application.*" }

Output:

Resources included

Prevention

• Add reflection and resource hints
• Use AOT processing before native compilation
• Test native image with integration tests

Common Mistakes with boot graalvm native

1. Overlapping type class instances that cause GHC to reject the program with ambiguous dispatch errors
2. Non-exhaustive pattern matches that compile with warnings then crash at runtime
3. Misunderstanding that String is [Char] with poor performance for large text operations

These mistakes appear frequently in real-world SPRING code. DodaTech's contributors have identified these patterns through analysis of open-source projects and production systems.

Practice Exercise

Write a pure function that safely divides two integers using Maybe, then test it with edge cases like division by zero and negative numbers.

This exercise reinforces the concepts covered in this guide. Try implementing it before checking online solutions.
