Deploy your Java app to DigitalOcean
Step-by-step deployment help for Java apps on DigitalOcean. We fix Java-specific deployment issues, configure DigitalOcean, and get your app live. From $19.
Java issues we fix before deploying
Common Java problems that affect DigitalOcean deployments.
SQL injection via string concatenation
Building SQL queries with string concatenation instead of PreparedStatement or parameterized JPA queries, allowing attackers to manipulate database operations.
Missing input validation
Controller endpoints accept request bodies without Bean Validation annotations (@Valid, @NotNull, @Size), allowing malformed data into business logic.
Thread safety issues
Mutable shared state accessed from multiple threads without synchronization, volatile, or concurrent collections — causing race conditions in production.
Resource leaks
Database connections, streams, and file handles opened without try-with-resources, leading to connection pool exhaustion and OutOfMemoryErrors.
DigitalOcean deployment issues we check for
Common DigitalOcean problems that break Java apps in production.
App Platform buildpack fails to detect framework
AI-generated project structures with non-standard entry points or missing start scripts cause DigitalOcean's buildpack to fail during auto-detection.
Managed database connection pool exhaustion
AI tools create a new database connection per request instead of using a connection pool, exhausting DigitalOcean's managed database connection limits quickly.
Droplet firewall not configured
Freshly provisioned Droplets have all ports open by default. AI deployment scripts skip firewall configuration, exposing SSH, database, and admin ports publicly.
Spaces CDN CORS not configured
DigitalOcean Spaces requires explicit CORS headers for browser-based uploads. AI-generated frontend code fails silently when uploading files directly to Spaces.

Frequently asked questions
How do I deploy a Java app to DigitalOcean?
We handle Java deployments to DigitalOcean end to end. Start with our code audit ($19) to identify deployment blockers specific to your Java project, then we configure DigitalOcean, fix issues, and get your app live in production.
What Java issues affect DigitalOcean deployments?
Java projects commonly have sql injection via string concatenation and missing input validation. On DigitalOcean, these combine with app platform buildpack fails to detect framework and managed database connection pool exhaustion to cause deployment failures.
Can SpringCode deploy my Java project to DigitalOcean?
Yes. We specialize in deploying Java applications to DigitalOcean. We audit your codebase for Java-specific issues, configure DigitalOcean correctly, and handle the full deployment so your app runs reliably in production.
What does Java deployment to DigitalOcean cost?
Our code audit ($19) identifies all DigitalOcean deployment blockers in your Java project. Full deployment assistance is scoped with a fixed quote after the audit — no hourly billing or surprise charges.
