Spring Data JPA EntityGraph

Life without spring-data-jpa-entity-graph

Spring Data JPA only supports EntityGraph through annotations.
Thus, for a repository method, you must select at most one EntityGraph before compilation.
This prevents you from choosing the best EntityGraph considering the runtime context 💔

Life with spring-data-jpa-entity-graph

Thanks to spring-data-jpa-entity-graph, you can choose EntityGraph at runtime!
This choice is elegantly made by passing EntityGraph, as an argument, to any Spring Data JPA repository method 😍

Example:

// This will apply 'Product.brand' named EntityGraph to findByLabel
productRepository.findByLabel("foo", EntityGraphs.named("Product.brand"));

// This will apply 'Product.supplier' named EntityGraph to findByLabel
productRepository.findByLabel("foo", EntityGraphs.named("Product.supplier"));

Now run to the documentation !

Documentation

This library follows the Spring Data JPA versionning semantic.

spring-data-jpa branches Latest spring-data-jpa-entity-graph version Documentation
2.1.x Maven Central Latest 2.1.x documentation
2.0.x Maven Central 2.0.x 2.0.x documentation
1.11.x Maven Central 1.11.x 1.11.x documentation
1.10.x Maven Central 1.10.x 1.10.x documentation

Example: if you were using spring-data-jpa 1.10.13 in your project, you would need to select any spring-data-jpa-entity-graph 1.10.x. Thus spring-data-jpa-entity-graph 1.10.14 would be eligible.

Genesis

This project was created following the discussion in Spring Data Tracker issue DATAJPA-749 - Context enabled JPA 2.1 @EntityGraph .

You can’t perform that action at this time.
