Not an instance of a persistable class [DATAGRAPH-891]

[spring-projects-issues]

Sebastian Glahn opened DATAGRAPH-891 and commented

I have a Spring Boot project which uses Spring Data Neo4j. When I run the project from my IDE(Intellij) everything works fine. When I run the project from command line(java -jar ...) I get the message that my entity is not an instance of a persistable class.
I pass the basePackages to the SessionFactory:

@Bean
public SessionFactory getSessionFactory() {
    return new SessionFactory(getConfiguration(), basePackages);
}

And I have annotated the main class with:

@EnableNeo4jRepositories(basePackages = "org.sgh.persistence")

The info log shows the following:

Although the debug logs shows that the ClassPathScanner is scanning the correct classes:

I have created a minimal demo project on Github to reproduce the problem: https://github.com/sglahn/spring-data-neo4j-demo
To reproduce the problem do the following: Build the jar:

./gradlew build

Execute the jar:

java -Dspring.config.location=build/resources/main/ -jar build/libs/spring-data-neo4j-example-0.0.1-SNAPSHOT.jar

Access the Controller in the browser:

http://localhost:8765/

The log shows:

org.sgh.persistence.TreeEntity is not an instance of a persistable class

When deployed as exploded jar the project runs fine.

Spring Boot version is 1.4.0.RC1

Affects: 4.0 GA, 4.1.1 (Hopper SR1), 4.1.2 (Hopper SR2)

This is actually fixed in the underlying OGM library dependency, and will be available in the next service release of Spring Data Neo4j.

In the meantime please see https://github.com/neo4j-examples/sdn4-university for details of a workaround.
