Spring Hibernateクエリがプロパティを解決できませんでした

Question

1人のスタッフが1人のレポート担当者に報告し、1人のレポート担当者が複数のスタッフを持つことができます。言ったことで

、私は自己マッピングされ、それらを一緒にStaff.java

//reporting officer 
@ManyToOne (cascade = {CascadeType.MERGE, CascadeType.DETACH, CascadeType.REFRESH}) 
@JoinColumn(name = "reporting_officer_id") 
private Staff reportingOfficer; 

そして、私のデータベース

CREATE TABLE `tbl_staff` (
    `id` INT NOT NULL AUTO_INCREMENT, 
    `staff_no` INT(5) NOT NULL, 
    `staff_name` VARCHAR(25) NOT NULL, 
    `login_id` VARCHAR(16) NOT NULL, 
    `date_of_birth` DATE NULL DEFAULT NULL, 
    `joined_date` DATE NULL DEFAULT NULL, 
    `department_id` INT NULL DEFAULT NULL, 
    `designation` VARCHAR(255) NULL DEFAULT NULL, 
    `reporting_officer_id` INT NULL DEFAULT NULL, 
    `photograph` BLOB NULL DEFAULT NULL, 
    FOREIGN KEY (`department_id`) REFERENCES tbl_department(`id`), 
    PRIMARY KEY (`id`) 
); 

に、私はこのクエリを実行しようとしている中を持っている...

@Query("FROM Staff t WHERE " + "t.reporting_officer_id=:reportingOfficerId") 
    public List<Staff> findStaffsWithSameReportingOfficer(@Param("reportingOfficerId") int reportingOfficerId); 

このエラーが発生しています...
