Here is my entire Jpa/Neo4J Setup. Maybe I overlooked something? In the
meantime I will remove @Transient from the collections, resort back to the
stage where I got the Exception (see initial post).
//Jpa Setup
@Configuration
@EnableTransactionManagement(mode=AdviceMode.ASPECTJ)
@EnableJpaRepositories(value={"com.repository"},
entityManagerFactoryRef="entityManagerFactory",
transactionManagerRef="transactionManager")
@PropertySource("classpath:db.properties")
public class JpaConfig {
@Autowired
private Environment environment;
@Bean
public PlatformTransactionManager transactionManager() {
JpaTransactionManager txManager = new JpaTransactionManager();
txManager.setEntityManagerFactory((EntityManagerFactory)
entityManagerFactory());
return txManager;
}
@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
LocalContainerEntityManagerFactoryBean factory = new
LocalContainerEntityManagerFactoryBean();
factory.setJpaVendorAdapter(new HibernateJpaVendorAdapter());
factory.setPackagesToScan("com.equitytwits.core");
factory.setJpaPropertyMap(AppUtil.jpaProperties());
factory.setDataSource(dataSource());
return factory;
}
@Bean
public DriverManagerDataSource dataSource(){
DriverManagerDataSource driverManagerDataSource = new
DriverManagerDataSource();
driverManagerDataSource.setDriverClassName(environment.getRequiredProperty("jdbc.driverClassName"));
driverManagerDataSource.setUrl(environment.getRequiredProperty("jdbc.url"));
driverManagerDataSource.setUsername(environment.getRequiredProperty("jdbc.username"));
driverManagerDataSource.setPassword(environment.getRequiredProperty("jdbc.password"));
return driverManagerDataSource;
}
}
//Neo4j Setup
@Configuration
@ComponentScan(basePackages={"..."})
@EnableTransactionManagement(mode=AdviceMode.ASPECTJ)
@EnableNeo4jRepositories(value={"..."})
public class Neo4JConfig extends Neo4jConfiguration{
@Bean(destroyMethod = "shutdown")
@Scope(SCOPE_PROTOTYPE)
public SpringRestGraphDatabase graphDatabaseService(){
SpringRestGraphDatabase springRestGraphDatabase = new
SpringRestGraphDatabase("http://localhost:7474/db/data";);
return springRestGraphDatabase;
}
@Bean
public Neo4jTemplate neo4jTemplate(){
return new Neo4jTemplate((GraphDatabase) graphDatabaseService());
}
@Bean
public Neo4jMappingContext neo4jMappingContext() {
return new Neo4jMappingContext();
}
}
