|

## Support for Query-by-Example
|
|
|
|
Query by Example (QBE) is a user-friendly querying technique with a simple interface. It allows dynamic query creation and does not require to write queries containing field names. In fact, Query by Example does not require to write queries using JPA-QL at all.
|
|
|
|
An `Example` takes a data object (usually the entity object or a subtype of it) and a specification how to match properties. You can use Query by Example with JPA Repositories.
|
|
|
|
This example contains a test class to illustrate Query-by-Example with a Repository in `UserRepositoryIntegrationTests`.
