Grails 2.4.3 + Neo4j Plugin = No bean named 'sessionFactory' - grails

Question

I want to create a sample app in Grails with Neo4J. (on IntelliJ)
After creating a simple app and added the necessary configurations inside Buildconfig.groovy
Repo
mavenRepo 'http://m2.neo4j.org/content/repositories/releases/'
Plugin
compile ":neo4j:2.0.0-M02"
I want to use MySql and Neo4J at the same time (adding mapping inside the domain model, when I want neo4j).
But I have this error:
Error |
2014-12-14 19:05:59,261 [localhost-startStop-1] ERROR context.GrailsContextLoaderListener - Error initializing the application: No bean named 'sessionFactory' is defined
Message: No bean named 'sessionFactory' is defined
Line | Method
->> 104 | postProcessBeanFactory in org.grails.datastore.gorm.plugin.support.PersistenceContextInterceptorAggregator
What am I doing wrong ?

Answer 1

having same problem - if I removed the neo4j plugin - and create an ordinary domain class+test works fine
as soon as you enable the neo4j plugin (2.0.0-M2) - and run the same test again it fails with the errors above -
no idea how enabling the neo plugin removed the sessionFactory bean that grails normally setsup
something cooky going on

Answer 2

tried to cheat and added this to the resources.groovy beans
...
sessionFactory(ConfigurableLocalSessionFactoryBean) {
dataSource = ref('dataSource')
hibernateProperties = ["hibernate.hbm2ddl.auto": "create-drop",
"hibernate.show_sql": "true"]
}
and tried to re run the test - still fails as it says that in error
..Message: No such property: ConfigurableLocalSessionFactoryBean for class: resources
so its somewhere deep in the bowels...

Answer 3

Finally I found a solution: Do not use this plugin. I prefer to use a micro service architecture. I created an application with Spring Boot, Groovy and Neo4J. I omitted controllers, model and spring repositories.
build.gradle
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath("org.springframework.boot:spring-boot-gradle-plugin:1.2.2.RELEASE")
}
}
apply plugin: 'groovy'
apply plugin: 'idea'
apply plugin: 'spring-boot'
jar {
baseName = "it.luis"
version = '0.1-SNAPSHOT'
}
repositories {
mavenCentral()
jcenter()
maven { url "http://m2.neo4j.org/content/repositories/releases/" }
maven { url "https://repo.spring.io/libs-release" }
}
dependencies {
// compile 'org.codehaus.groovy:groovy-all:2.4.0'
compile localGroovy()
compile("org.springframework.boot:spring-boot-starter-web")
compile("org.springframework.boot:spring-boot-starter")
compile("org.springframework:spring-context")
compile("org.springframework:spring-tx")
compile("org.springframework.data:spring-data-neo4j")
compile("org.hibernate:hibernate-validator")
compile("org.springframework.boot:spring-boot-starter-actuator")
compile("javax.el:javax.el-api:2.2.4")
testCompile("junit:junit")

}
