How to ignore null and empty value when use Neo4jOperations.save() to update properties with Spring Data Neo4j? -

spring-data-neo4j : 4.1.2
neo4j:3.0.3

node :

person {id:1, name:"aa", cover:"1.jpg"}

class:

@nodeentity public class person{     @graphid     private long id;     private string name;     private string cover;     ... }

new object:

person p = new person(); p.setid(1); p.setname("bb");

then update data:

p = neo4joperations.save(p,0);

or:

personrepo.save(p,0); // interface extends graphrepository<person>

result:

person {id:1, name:"bb"}
