ArchUnit Rule to detect eagerly fetched JPA associations, because we don't like global fetch plans! Make sure to read https://vladmihalcea.com/eager-fetching-is-a-code-smell/

Usage

Import in pom.xml:

<dependency>
    <groupId>de.christianvogt</groupId>
    <artifactId>archunit-jpa-rules</artifactId>
    <version>1.5</version>
</dependency>

Add a Test and import the ArchRule:

(...)
import static de.christianvogt.archunit.JpaRules.NO_EAGER_LOADING_ENTITY_ASSOCIATIONS;

@AnalyzeClasses(packages = "org.example")
class MyJpaTest {
    @ArchTest
    private ArchRule no_eager_loading = NO_EAGER_LOADING_ENTITY_ASSOCIATIONS;
}

The test will fail when any JPA association is eagerly fetched.
