> Component for neo4j
> -------------------
>
> Key: CAMEL-5483
> URL: https://issues.apache.org/jira/browse/CAMEL-5483
> Project: Camel
> Issue Type: Improvement

> Assignee: Willem Jiang
> Priority: Blocker
> Fix For: 2.11.0

> Attachments: camel-neo4j.patch, remove-int-tests.patch

> I have created a component for neo4j. It is a producer only and it allows you to create / remove nodes and relationships.
> ------ read me ----------
> camel-neo4j
> ========
> The camel-neo4j component allows you to treat Neo4j as a camel producer endpoint. This means you can use this component in to() calls but not from() calls. This component is backed by the Spring Data Neo4j Library.
> * As a producer, can create or remove nodes, and create or remove relationships.
> * Can support as many endpoints as required, eg for multiple databases across multiple instances.
> * Headers set for node id (for created nodes), relationship id (for created relationships)
> How to Use
> ==========
> You can use neo4j as an endpoint with the following URI.
> `neo4j:http://hostname[:port]/database`
> Then you need to set a header on each message, one of the following enum types
> ` CREATE_NODE,
> REMOVE_NODE,
> CREATE_RELATIONSHIP,
> REMOVE_RELATIONSHIP`
> Eg,
> `exchange.getIn().setHeader(Neo4jEndpoint.HEADER_OPERATION, Neo4jOperation.CREATE_NODE);`
> The body of the message is used to determine the node or relationship to manipulate. The following body types are supported:
> For CREATE_NODE:
> * null body - create default node
> * Map body - create node with the properties set from the map
> For REMOVE_NODE:
> * Long or Integer - remove node using the body as the id
> * neo4j Node instance - remove the node specified by that instance
> For CREATE_RELATIONSHIP:
> * SpringDataRelationship - create relationship specified by any @NodeEntity annoted Spring entities.
> * BasicRelationship - create relationship specified by the neo4j node types
> For REMOVE_RELATIONSHIP:
> * Long or Integer - remove relationship using the body as the id
> * SpringDataRelationship - remove relationship specified by the @NodeEntity annoted Spring entities.
> * BasicRelationship - remove relationship specified by the neo4j node types
> Tests
> =====
> camel-neo4j has a complete set of unit tests. In addition there are some integration tests that require you to run a local instance of neo4j. By default the tests will look at localhost:7474 on http://localhost:7474/db/data/
