This is an oversight / bug in the Spring Boot autoconfiguration for SDN. I'll PR a fix with the team over there. import java.util.Set;
import org.springframework.boot.autoconfigure.domain.EntityScanner;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.neo4j.aot.Neo4jManagedTypes;
import org.springframework.data.neo4j.core.convert.Neo4jConversions;
import org.springframework.data.neo4j.core.mapping.Neo4jMappingContext;
import org.springframework.data.neo4j.core.schema.Node;
import org.springframework.data.neo4j.core.schema.RelationshipProperties;
@Configuration(proxyBeanMethods = false)
public class F {
@Bean
Neo4jManagedTypes neo4jManagedTypes(ApplicationContext applicationContext) throws ClassNotFoundException {
Set<Class<?>> initialEntityClasses = new EntityScanner(applicationContext).scan(Node.class,
RelationshipProperties.class);
return Neo4jManagedTypes.fromIterable(initialEntityClasses);
}
@Bean
public Neo4jMappingContext neo4jMappingContext(Neo4jManagedTypes managedTypes,
Neo4jConversions neo4jConversions) {
Neo4jMappingContext context = new Neo4jMappingContext(neo4jConversions);
context.setManagedTypes(managedTypes);
return context;
}
}Please let me know if this works for you. |

I have tested it in my project and it's working like a charm. Thanks for the amazing support and the quick solution to the problem! |

Thank you for using and reporting it :) The improvement on Spring Boot side of things is great. |

Uh oh!
There was an error while loading. Please reload this page.
Hello,
I have a Spring Boot Webflux application and want to create a native image. There I came across two different issues.
1. Saving nodes:
I'm getting an error when saving an node with a reactive repository. I was able to identify the problem. It seems that (at least) the runtime hint for the
ReactiveBeforeBindCallbackis missing. When adding the class to my projects runtime hints the saving of a node works as expected.For the non-reactive class the hint is present (Neo4jRuntimeHints.java#L51) and saving works as expected.
2. Repository with abstract base class:
I have a class hierarchy setup where I have an abstract parent node class and several child classes (see below).
According to the section A note on class hierarchies this use case is supported.
Saving a
ChildNodeAworks as expected resulting in a node with both labelsParentLabelandChildALabel.But when calling the
findByNamequery an exception is thrown where it seems that it's tried to create an instance ofParentNodeinstead ofChildNodeA. Here I didn't found a solution myself.This behavior is the same for both the reactive repository and the non-reactive repository. If not using graalvm the child class is correctly resolved and instanciated.
Below the exception from the reactive case:
