Deploy your Java app to Firebase Hosting
Step-by-step deployment help for Java apps on Firebase Hosting. We fix Java-specific deployment issues, configure Firebase Hosting, and get your app live. From $19.
Java issues we fix before deploying
Common Java problems that affect Firebase Hosting 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.
Firebase Hosting deployment issues we check for
Common Firebase Hosting problems that break Java apps in production.
Firestore security rules allow public read/write
AI tools set Firestore rules to allow read, write: if true for development and never lock them down, exposing the entire database to any authenticated or anonymous user.
Cloud Functions cold start on free Spark plan
Firebase Cloud Functions on the Spark plan have aggressive cold starts and limited concurrency, causing 5-15 second delays on first invocation.
firebase.json rewrites not matching SPA routes
Single-page app routing requires a rewrite rule in firebase.json to send all requests to index.html. AI tools either omit this or misconfigure it alongside Cloud Functions rewrites.
Storage rules expose private user files
Firebase Storage rules generated by AI allow any authenticated user to read any file, rather than restricting access to the file owner.
