Migrating Struts to Spring Boot: Eliminating Security Risk with Automation

ResQSoft LLC

Organizations that still run on Struts are carrying a serious liability. Struts 1.x has been unsupported for years, and even Struts 2 has seen major security breaches. In some cases, vulnerabilities are never patched at all — leaving enterprises exposed to data breaches, compliance failures, and reputational damage.

By contrast, Spring Boot is actively maintained, widely adopted, and strengthened by a large developer community. Vulnerabilities are tested, identified, and patched quickly. Migrating from Struts to Spring Boot isn’t just a technical upgrade — it’s a critical step in protecting your systems.

At ResQSoft, we make that migration faster, safer, and more predictable through automation.

Why Struts Migration Matters

Enterprises that continue to run Struts face three major challenges:

  • Security exposure — vulnerabilities with no patches available.
  • Lack of vendor support — no roadmap or guarantees for bug fixes.
  • Developer scarcity — fewer engineers today know or want to work in Struts.

Spring Boot addresses all of these issues: it’s secure, scalable, and developer-friendly, with a vibrant ecosystem of tools and frameworks. The question is no longer whether to migrate, but how.

Automation: The Key to Migration

Manual Struts-to-Spring conversions are slow and prone to errors. ResQSoft eliminates that burden with automation-assisted tools that convert the repetitive, mechanical parts of the migration. These tools:

  • Replace Struts JARs with Spring Boot equivalents.
  • Refactor controllers, dispatchers, and configuration.
  • Convert Struts tags into modern HTML or Thymeleaf templates.

Automation typically handles 70–80% of the work, producing consistent, clean code. Developers can then focus on refining business logic, integrating with other systems, and validating workflows.

Two Engagement Models

ResQSoft offers two levels of engagement, giving customers flexibility based on their needs:

  1. Tool-Assisted Migration
    • We run our tools on your Struts application.
    • You receive the converted code to review, refine, and complete the migration in-house.
    • Ideal for IT teams that want to stay hands-on but accelerate efforts with proven automation.
  2. Full-Service Modernization
    • We handle the entire migration on a fixed-price basis.
    • Includes not only Struts-to-Spring Boot conversion, but also optional upgrades like replacing JSP pages with a React or Angular front end.
    • Delivers a fully modernized, cloud-ready system without open-ended consulting costs.

    Testing: Automated and Essential

    Testing is not optional — it’s critical to a successful migration. At ResQSoft, we recommend and support test automation to ensure functionality is preserved and performance is stable throughout the migration.

Our approach covers:

  • Unit and integration tests for migrated code.
  • Regression testing to confirm that existing workflows still function.
  • Automated test frameworks to reduce reliance on manual keyboard-driven testing and increase coverage.

This gives organizations confidence that the migrated system is reliable and production-ready.


Security First

Unlike Struts, which often leaves vulnerabilities unpatched, Spring Boot benefits from constant scrutiny, frequent bug fixes, and a large community of contributors. Migrating to Spring Boot significantly strengthens your application security posture.

When auditors, regulators, or security teams ask, “Why are you still running unsupported Struts?” — modernization to Spring Boot provides the answer they want to hear.
ResQSoft: Modernization Beyond Struts
At ResQSoft, we don’t just migrate frameworks — we modernize applications. Our automation-assisted approach, combined with fixed-price development packs, ensures:

  • Predictable costs without hourly rate cards.
  • Automation handling most of the mechanical work.
  • Flexible delivery models: tool-assisted for your team, or full-service with added enhancements.
  • Secure, maintainable, cloud-ready applications that your developers can support long term.

By choosing ResQSoft, enterprises eliminate the risks of Struts and gain the flexibility of Spring Boot — with minimal disruption and maximum security.

Closing Note

Struts is an artifact of the past. Every day it stays in production increases security risk and operational cost. Spring Boot is the secure, modern foundation enterprises need.

With ResQSoft, migration doesn’t have to mean long, risky projects. Our automation-assisted approach delivers speed, accuracy, and choice — whether you want to do it yourself with our tools, or let us deliver a fully modernized system, complete with a modern UI.

FAQs
Q1. Why migrate from Struts to Spring Boot?
Struts is end-of-life and insecure; Spring Boot is secure, supported, and future-ready.

Q2. What happens to our data?
Your database remains unchanged. Migration targets the application layer, not the data layer.

Q3. How does automation help?
It converts most of the mechanical code changes, accelerating delivery and reducing errors.

Q4. Do we have to hand everything over to ResQSoft?
No. You can choose tool-assisted migration to complete in-house, or full-service modernization for a turnkey upgrade.

Q5. How is security improved?
Spring Boot benefits from active testing, frequent bug fixes, and vendor support — unlike Struts, which often leaves vulnerabilities unresolved.
