Debugging & Troubleshooting — LazyInitializationException & Common Production Failures
The capstone troubleshooting chapter — a fast, symptom-to-cause map back into every earlier chapter's mechanism, for the moment you're actually debugging a real, live production persistence-layer issue and need to move fast.
Learning objectives
- Map a LazyInitializationException, an N+1 slowness pattern, connection pool exhaustion, and a race-condition constraint violation each back to its root cause.
- Diagnose a production persistence-layer issue using SQL logging, Hibernate statistics, and connection pool metrics before guessing.
- Identify and avoid the 'fix the symptom, not the cause' anti-patterns common to each of these four failure modes under real incident pressure.
