Neo4j: spring-data-neo4j,how to cast result to my type class? - casting

Question

I have insert some node into Neo4j DB.And I want to select some node from database and cast it to specific class.
Here are some code about the problem:
class Service {
Neo4jTemplate neo4jTemplate
#Transactional
def find() {
def id1 = 11
//Knowledge k = neo4jTemplate.findOne(1, Knowledge)
Result result = neo4jTemplate.query("start n=node(11) return ID(n),n.name,n.age;", null)
//how to cast the result to User class
println "the tpye of result called User is "+ result.to(User.class).is(cn.edu.bnuz.itc.bok.sub2.User.class)
}
}
The detail about node like :
+-------------------------------------------------------------------------+
| Node[11]{career:"programmer",name:"kelvin",age:35,introduce:"lazy doy"} |
+-------------------------------------------------------------------------+
#NodeEntity
class User {
#GraphId
Long id;
String name;
int age;
}
I just want get the node's id, name, age from db and put it into a User class.
But it failed many time with many method.
Here I have encounter a problem which is :How can I cast the result to my target class? I have try many method to cast but fail finally.Thank you for you attention.

Answer 1

Return the user node from the query and call the to method of the returned Result with the desired class as argument:
Result result = neo4jTemplate.query("start n=node(11) return n", null);
for(User u : result.to(User.class)) {
doSomethingWith(u);
}
You may want to consider using repositories that support cypher queries like:
public interface UserRepository extends GraphRepository<User> {
#Query("start n=node(11) return n")
Iterable<User> getUser11();
}
