Question

我是springbootneo4j的新手。我在进行通用查询时遇到困难。我希望能够进行任何类型的查询并获得没有域实体的结果。

我正在存储库类中进行如下查询：

@Query("MATCH (p:Employee) RETURN ID(p) as id, p.name as name, p.salary as salary ")

那不起作用，但是以下查询正在起作用：

@Query("MATCH (p:Employee) RETURN p ")

我的域实体类是这样的：

@NodeEntity
public class Employee {
    @Id
    @GeneratedValue
    private Long id;
    private String name;
    private int salary;

    @Relationship(type = "IS_BOSSOF", direction = Relationship.UNDIRECTED) Set<Employee> reporties = new HashSet<>();

    public Employee() {}

    // some more code
}

创建命令是这样的：

(laksmi:Employee{name:"Laksmi",salary:200}),(ashwini:Employee{name:"AshwiniV",salary:300}),  (harish:Employee{name:"Harish",salary:400}),  (jay)-[:IS_BOSSOF]->(mukesh),   (xyz)-[:IS_BOSSOF]->(mukesh),    (harish)-[:IS_BOSSOF]->(ashwini),

Answer 1

每当分配属性时，都需要在类上使用@QueryResult批注 SDN

没有域实体，无法进行通用查询
