@DeleteMapping("/luckymoneys/{id}")
public?Result?deleteById(@PathVariable?Integer?id){
????service.delete(id);
???return??ResultUtil.success(null);

}

public?void?delete(Integer?id)?{
????Luckymoney?luckymoney?=?new?Luckymoney();
????luckymoney.setId(id);

????repository.delete(luckymoney);
}

@Pointcut("execution(public?*?com.imooc.luckymoney.controller.LuckMoneyController.*(..))?&&?!execution(public?*?com.imooc.luckymoney.controller.LuckMoneyController.delete*(..))"?)
public?void?log()?{

}

把delete從切入表達(dá)式中去除?；蛘咝露x一個(gè)切入表達(dá)式，讓delete方法使用該切入點(diǎn)↓

@Pointcut("execution(public?*?com.imooc.luckymoney.controller.LuckMoneyController.*(..))?&&?!execution(public?*?com.imooc.luckymoney.controller.LuckMoneyController.delete*(..))"?)
public?void?logByDel(){

}

@DeleteMapping("/girls/{id}")
public?void?girlDelete(@PathVariable("id")?Integer?id){
????????girlRepository.deleteById(id);
????throw?new?GirlException(ResultEnum.SUCCESS);
}

無返回值的加個(gè)

throw?new?GirlException(ResultEnum.SUCCESS);

就餓可以了

應(yīng)該是deleteGirl方法沒有返回值，所以（@AfterReturning(returning?=?"object",pointcut?=?"log()")）doAftereReturning方法中參數(shù)Object為null，然后toString報(bào)的空指針吧

我的也會(huì)出現(xiàn)這種情況，能成功刪除數(shù)據(jù)，但是會(huì)報(bào)空指針錯(cuò)誤！

數(shù)據(jù)庫(kù)沒數(shù)據(jù)吧
