将Neo4j Java节点和关系对象嵌入到JSON

Question

Am using Neo4j 2.0.1 as Embedded db in java application. Querying in java and getting Nodes and Relationship objects. How can we convert this to JSON format ? So that it will be fed to d3.js for visualization. Is there any Neo4j Java API methods exists ?

Answer 1

You could create domain entities from your nodes and annotate them with Jackson annotations. Converting a pojo to JSON is as easy as

ObjectWriter ow = new ObjectMapper().writer().withDefaultPrettyPrinter();
String json = ow.writeValueAsString(object);
