SpringBoot整合Neo4j
依赖
<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-data-Neo4j</artifactId>
</dependency>配置
spring:data:neo4j:uri: bolt://127.0.0.1:7687username: neo4jpassword: neo4j类似于jpa模式，同样是构建 model 层、repository 层，然后在此基础上操作自定义或模板方法。
实体类
节点
@Data
@NodeEntity(label = "Person")
public class Node {@Id@GeneratedValueprivate Long id;@Property(name = "name")private String name;@Property(name = "title")private String title;
}关联关系
@Data
@RelationshipEntity(type = "DOWNSTREAM_OF")
public class DownstreamOfRelationShip {@Id@GeneratedValueprivate Long id;@StartNodeprivate Person startNode;@EndNodeprivate Person endNode;@Property("relation_ship_id")private String relationShipId;
}持久层
@Repository
public interface NodeRepository extends Neo4jRepository<Node,Long> {@Query("MATCH p=(n:Person) RETURN p")List<Node> selectAll();@Query("MATCH(p:Person{name:{name}}) return p")Node findByName(String name);
}使用
@Slf4j
@Service
public class NodeServiceImpl implements NodeService {@Autowiredprivate NodeRepository nodeRepository;@Overridepublic Node addNode(Node node) {Node node = nodeRepository.save(node);return node ;}public Node findNode(String name) {Node node = nodeRepository.findByName(name);return node;}
}
