TL;DR

• Scenario: Java applications need to integrate with FastDFS distributed file system
• Conclusion: Both methods can achieve connection: source compilation or direct Maven dependency
• Output: Directly reusable code examples and configuration templates

Troubleshooting

Symptom	Root Cause	Fix
getStoreStorage returns null	Check Tracker/Storage status	Use fdfs_monitor
Connection refused	Tracker address and firewall	Verify address and firewall settings
SocketTimeoutException	Timeout value too small	Increase timeout
NoSuchMethodError	Dependency conflict	Check dependency versions
404 error	Nginx reverse proxy not configured	Configure Nginx access path
