修复Label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

实现这一目标的唯一方法是实施TransactionEventHandler。有关此内容的详细说明，请参阅https://maxdemarzi.com/2015/03/25/triggers-in-neo4j/。
