spring-data-neo4j，手动获取relatedTo实体

Question

@NodeEntity
@JsonIgnoreProperties(ignoreUnknown = true)
public class Employee {
    @GraphId
    private Long graphId;

    @Indexed
    private Long id;

    private String name;

    private String password;

    @RelatedTo(type = "REPORT_TO", direction = Direction.OUTGOING)
    private Department department;
}

I know spring-data-neo4j can use @Fetch to get Department data when get Employee entity, but not every time I need Department when get Employee, so how can I fetching department manully? The @Fetch annotation is not flexible

Answer 1

You can use Neo4jTemplate#fetch (T) to do manually what @Fetch does automagically.

See api doc here .
