Exception thrown when connecting Neo4j+HA and Spring Data- "Missing Mandatory Setting ha.initial_hosts"

Question

I am trying to create a sample node in Neo4j Graph DB but getting an exception when starting tomcat. I am using Neo4j+HA+Spring Data Graph Repository to create a node. I am sure there is something wrong on how I configured. I am getting below exception. All my 3 neo4j clusters are configured and started.I used exact configuration as specified in the link Neo4j HA Conf Tutorial

Let me know if you want me to paste any of other code/classes.

I see below exception.

    Could not instantiate bean class [org.neo4j.kernel.HighlyAvailableGraphDatabase]: 
Constructor threw exception; nested exception is java.lang.IllegalArgumentException: 
Missing mandatory setting 'ha.initial_hosts'

Below is the complete exception.

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'homeController': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: com.estimates.topack.services.PersonService com.estimates.topack.HomeController.personServices; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'personService': Cannot resolve reference to bean 'neo4jTemplate' while setting bean property 'neo4jTemplate'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.data.neo4j.aspects.config.Neo4jAspectConfiguration#0': Cannot resolve reference to bean 'haDatabase' while setting bean property 'graphDatabaseService'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'haDatabase' defined in ServletContext resource [/WEB-INF/spring/appServlet/applicationContext.xml]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [org.neo4j.kernel.HighlyAvailableGraphDatabase]: Constructor threw exception; nested exception is java.lang.IllegalArgumentException: Missing mandatory setting 'ha.initial_hosts'

Answer 1

The config of bean haDatabase is incomplete. Neo4j 1.9.x does not use ha.coordindator, use ha.initial_hosts instead. ha.coordinator was used up to 1.8.x.
