Hibernate Mapping for a Happy REST
See the companion article here http://revelfire.com/hibernate-mappings-performance-serialization/
Demonstrates idealized hibernate mappings for optimal performance and serialization.
You have a mysql database on localhost:3306 with a schema created called model_test with user root, no password. Adjust the gradle file properties to match your settings if these are not yours.
This project demonstrates from very simple examples of Hibernate mappings which are designed with the following goals in mind:
- Minimize the object graph
- Prevent stack overflow errors on serialization
- Prevent massive descent into the object graph on serialization
- Model the data closely to how it gets accessed
- Keep it simple
Some guiding principles
- No bidirectional relationships
- Minimize entity relationships, maximize use of keys
- Allow services to set relationships WHEN they matter
- Allow HQL/Repository loads and services to load relationships WHEN they matter
