Hibernate / Hibernate Interview Questions III
Mention some of the Hibernate Best Practices.
- Identify natural keys for all entities, and map them.
- Place each class mapping in its own file.
- Externalize query strings to make applications more portable.
- Use bind variables to prevent SQL Injection.
- Use hand-coded JDBC sparing: Using SQL defeats the entire purpose of using Hibernate. So, use it sparingly, only when it is performance-critical.
- Prefer lazy fetching for associations. Explicitly disable eager fetching using lazy="false". When join fetching is appropriate to a particular use case, use a query with a left join fetch.
- Use bidirectional associations: In a large application, almost all associations must be navigable in both directions in queries.
