Question

刪除多行。在功能deleteDoctor，我想通過ID從表doctor刪除的醫生，並在同一時間，我想在user表誰擁有doctor的登錄刪除相關user。

然而，流動不工作，下面的代碼參考：

@DeleteMapping("/doctor/{id}") 
@Timed 
public ResponseEntity<Void> deleteDoctor(@PathVariable String id, 
             @RequestBody Doctor doctor) { 
    log.debug("REST request to delete Doctor : {}", id); 
    doctorRepository.delete(id); 

    userRepository.findOneByLogin(doctor.getLogin()). 
    ifPresent(user -> { 
     userRepository.delete(user); 
     log.debug("Deleted User: {}", user); 
    }); 

    return ResponseEntity.ok() 
    .headers(HeaderUtil.createEntityDeletionAlert(ENTITY_NAME, id.toString())).build(); 
} 

Answer 1

標註deleteDoctor()法@Transactional或更好：上下移動該代碼的服務方法與@Transactional
