我写了下面的代码来检索类实体。

@Repository
public interface ClassRepository extends ReactiveNeo4jRepository<Class, Long> {
    @Query("MATCH (project: Project) WHERE $pid in project.pids " +
            "MATCH (c: Class {name: $name})-[:relates*1..$depth]-(target: Class) " +
            "RETURN target")
    Flux<Class> findClassByName(@Param("name") String name, Long pid, @Param("depth") Long depth);
}

类实体是这样的。

@Node("Class")
@ToString
@Getter
@Setter
public class Class {
    @GeneratedValue
    @Id
    private Long id;
    private String url;
    private String name;
    private Boolean isAbstract;
    private Boolean isStatic;

    @Relationship(type="belongs_to_package", direction = Relationship.Direction.INCOMING)
    private Package aPackage;

    @Relationship(type = "relates", direction = Relationship.Direction.INCOMING)
    private Set<ClassRelationship> classRelates = new HashSet<>();
    @Relationship(type = "relates", direction = Relationship.Direction.INCOMING)
    private Set<InterfaceRelationship> interfaceRelates = new HashSet<>();
    @Relationship(type = "nested", direction = Relationship.Direction.INCOMING)
    private Set<Class> nested = new HashSet<>();

    public Class(String url, String name, Boolean isAbstract, Boolean isStatic, Package aPackage) {
        this.url = url;
        this.name = name;
        this.isAbstract = isAbstract;
        this.isStatic = isStatic;
        this.aPackage = aPackage;
    }
}

但它会产生这样的错误...

org.neo4j.driver.exceptions.ClientException: Parameter maps cannot be used in MATCH patterns (use a literal map instead, eg. "{id: {param}.id}") (line 1, column 97 (offset: 96))
"MATCH (project: Project) WHERE $pid in project.pids MATCH (c: Class {name: $name})-[:relates*1..$depth]-(target: Class) RETURN target"

当我将[：relates*1..$depth]更改为[：relates]时，它不会生成任何错误。因此，我知道错误是在哪里生成的，但我无法知道为什么会生成错误。
我能为它做些什么呢？
