Spring Hibernate - Find entities matching fields of another entity

原文 2019-02-18 16:35:09 9 1 java/ hibernate/ spring-data-jpa

I would assume that Hibernate would have a method of finding entities given another pre-populated entity, querying those who match.

As of my current knowledge; if I want to query an entity with a criteria of multiple fields I would need to add such a method in the CrudRepository interface which would look like this: findByFirstNameAndLastNameAndAddress... and then every combination i can think of.

Is there something along the lines of queryMatchingInstance(instance) ?

This feature is called query by example.

It is available in Hibernate directly .

And since you tagged the question with spring-data-jpa : Spring Data offers such a feature as well .

Hibernate - find entities, which has another entity inside set

Localization of entity fields in Spring Hibernate

Injecting fields via Spring into entities loaded by Hibernate

Inserting/Updating an entity with another referenced entities in Hibernate

Saving an array of Entities in another entity with Hibernate

Find parent entity using date range filter on child entities with Hibernate Search in Spring Boot

Spring Data: Create entities (and DB entries) using boolean fields of another entity

Spring, hibernate entity fields depending on profile

Hibernate: Mapping entity as list to two or more another entities

Deleting entity, which is element of collection and has collection of another entities in Hibernate
