What are JDBC connection leaks and how can I prevent them?

JDBC connection leaks occur when database connections are not properly closed, leading to resource exhaustion. To prevent them, always close connections in a finally block or use try-with-resources.

What are the common causes of these leaks?

Common causes include forgetting to close connections, using connection pools incorrectly, and exceptions that prevent closure.

How can I detect if my application has connection leaks?

You can monitor database connections using tools like JMX, or analyze logs for connection usage patterns. Profiling your application can also help.

Are there any libraries that can help manage JDBC connections?

Yes, libraries like HikariCP and Apache DBCP provide connection pooling and management features that help prevent leaks.

What should I do if I find a connection leak in my application?

If you find a leak, review your code to ensure all connections are closed properly. Consider implementing connection pooling and monitoring.
