当我运行下面的项目时，我收到了以下错误。我该如何修复它？
原因：java. lang.非法参数异常：无法为方法公共摘要com. example. pharmanic. model. Rdhs_Hospital_Current_Stock com. example. pharmanic. repository创建查询. Rdhs_Hospital_Current_StockRepository. findBysr_no（java. lang. String）!未找到类型Rdhs_Hospital_Current_Stock的属性sr!
这是我的Rdhs_Hospital_Current_Stock模型类。

@Entity
@Data
@Table(name = "Rdhs_Hospital_Current_Stock")
public class Rdhs_Hospital_Current_Stock {
    @Id
    private Long batchId;
    private int quantity;
    private String expiredate;

    @ManyToOne
    private Hospital_By_Rdhs hospital_by_rdhs;

    @ManyToOne
    @JoinColumn(name = "sr_no", nullable = false, referencedColumnName = "sr_no")
    private Medicine medicine;

}

sr_no是Medicine表的外键。
这是我的Medicine实体：

@Data
@Entity
public class Medicine {
    private @Id String sr_no;

    private String name;
    private String side_effect;
    private String description;

    public Medicine() {
    }

    public Medicine(String sr_no, String name, String side_effect, String description) {
        this.sr_no = sr_no;
        this.name = name;
        this.side_effect = side_effect;
        this.description = description;
    }
  }

当我将sr_no与findBy()函数一起使用时：

@GetMapping("/rhstock/{id}")
    ResponseEntity<?> getMedicine(@PathVariable String id){
        Optional<Rdhs_Hospital_Current_Stock> rdhs_hospital_current_stock = Optional.ofNullable(rdhs_hospital_current_stockRepository.findBysr_no(id));
         return rdhs_hospital_current_stock.map(response->ResponseEntity.ok().body(response)).orElse(new ResponseEntity<>(HttpStatus.NOT_FOUND));
    }

这是我的仓库：

public interface Rdhs_Hospital_Current_StockRepository extends JpaRepository<Rdhs_Hospital_Current_Stock,Long> {
    Rdhs_Hospital_Current_Stock findBysr_no(String id);

}
