修复标签的结构

Question

有没有办法在Neo4j中修复标签的结构？例如，修复标签：

Person { 
    name : String, 
    lastname : String 
} 

然后：

(p1:Person {name:"Jhon", lastname:"Doe"}) --> OK 

(p2:Person {name:"Jenny", lastname:"Doe", age:"18"}) --> error 

Answer 1

实现这一目标将会实现TransactionEventHandler的唯一途径。请参阅https://maxdemarzi.com/2015/03/25/triggers-in-neo4j/了解详情。
