Neo4j + Spring Boot 实战：从 Driver 到 Repository 的整合与踩坑

Maven pom.xml

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-neo4j</artifactId>
</dependency>

实体类

@Node
public class Person {
    @Id
    @GeneratedValue
    private Long id;

    @Property("cid")
    private int pid;

    @Property
    private String name;

    private double money;

    @Relationship(type = "Friends", direction = Relationship.Direction.INCOMING)
    private Set<Person> relationPersons;
}

DAO层

public interface PersonRepository extends Neo4jRepository<Person,Long> {
    @Query("match(p:Person) where p.money > {0} return p")
    List<Person> personList(double money);
}
