@PostMapping("/deleteTree/{id}")
public Result delate(@PathVariable("id") long id){
 try{
 stationRegionTreeService.delateTree(id);
 return Result.ok();
 }catch (Exception e) {
 e.printStackTrace();
 return Result.error(e);
 }
}



2.Service：
void delateTree(long id);


3.ServiceImpl:
@Override
public void delateTree(long id) {
 stationRegionTreeDao.deleteTreeById(id);
}


4.Dao:

@Transactional
@Modifying
@Query(value = "delete from StationRegionTree s where s.id = :id")
void deleteTreeById(@Param("id") long id);
