通过@Relationship指定类型为"ACTED_IN"、"DIRECTED"的关系,该关系默认指向List定义的Actor节点,也可以自己对关系进行定义。只要将一个Actor对象添加到actors的List中,就会自动创建指向本节点的关系。 @Node("Movie") public class Movie { @Id private final String title; @Property("tagline") private final String...
列到节点属性Column to Node Property——关系表上的列(字段)成为图中的节点属性。 仅业务主键Business primary keys only——删除技术主键,保留业务主键。 添加约束/索引Add Constraints/Indexes——为业务主键添加唯一约束,为频繁查找属性添加索引。 关系的外键Foreign keys to Relationships——用关系替换其他表的外键...
class Node(*labels, **properties) class Relationship(start_node, type, end_node, **properties) Node 和 Relationship 都继承了 PropertyDict 类,它可以赋值很多属性,类似于字典的形式,例如可以通过如下方式对 Node 或 Relationship 进行属性赋值,接着上面的代码,实例如下: ...
We can zoom in closer to a section of the results by using the trackpad on our laptop or mouse or by using the + and - buttons in the lower right of the scene. Once we zoom in a bit, we can see the property Bloom has assigned as the identifier for the node (in this case, ...

对于新的歌曲,首先通过Node指定name参数为歌名来创建一个节点对象。 对于当前节点对象,之后遍历nodeProperties列表给创建的节点对象添加属性,也就是遍历excel文件中当前行(歌曲名所在行)的["语种","原创所属"]这两列的数据作为属性,并通过类似于字典中键值对的赋值方法(enode[property] = value)给节点设置属性。
