Recently I've been playing with Spring Data for Neo4j (version 2.1.0.BUILD-SNAPSHOT
) and I'm having an issue related to its GraphRepository interface.
You can write a method that will search for a node of T class using the properties contained in the method's name, like this:
public interface UserRepository extends GraphRepository<User> {
public User findByUsername(String username);
public User findById(Long id);
}
My User class:
@NodeEntity
public class User {
@GraphId
Long id;
@Indexed
private String username;
private String password;
...
}
And my applicationContext.xml:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:neo4j="http://www.springframework.org/schema/data/neo4j"

<neo4j:repositories base-package="package.for.repositories" />
<neo4j:config graphDatabaseService="graphDatabaseService" />
<bean id="graphDatabaseService" class="org.neo4j.kernel.EmbeddedGraphDatabase"
destroy-method="shutdown" scope="singleton">
<constructor-arg value="/path/to/neo4j.db" />
<constructor-arg>
<map>
<entry key="allow_store_upgrade" value="true" />
</map>
</constructor-arg>
</bean>
</beans>
My issue is that findById(Long id)
method does return a node with that specific id, but findByUsername(String username)
does return null
instead of a node with that specific username.
Any help will be appreciated.
