Question

我正在制作一个休息api，其中我必须以id为基础更新并通过spring数据在表中插入没有id base的数据。但是我发现它运行的两个条件中的错误插入查询只更新不起作用

存储库文件 @Repository 公共接口CustomerRepository扩展了JpaRepository { CustomerEntity save（CustomerEntity customerEntity）; CustomerEntity findById（int id）;

访问管理器文件

public CustomerDO create（CustomerDO customerReqDO）{CustomerEntity customerEntity = null; CustomerDO customerResDO = new CustomerDO（）; if（null！= customerReqDO.getId（））{ customerEntity = customerRepository.findById（Integer.parseInt（customerReqDO.getId（）））; if（null！= customerEntity）{

            if(null != customerReqDO.getName())
                customerEntity.setName(customerReqDO.getName());

            if(null != customerReqDO.getPhone())
                customerEntity.setPhone(customerReqDO.getPhone());

            if(null != customerReqDO.getEmail())

                customerEntity.setEmail(customerReqDO.getEmail());

            if(null != customerReqDO.getPassword())
                customerEntity.setPassword(customerReqDO.getPassword());
            //if(null !=customerReqDO.getCredits())
                //customerReqEntity.setCredits(customerReqDO.getCredits());

            customerEntity =customerRepository.save(customerEntity);

          }else{
                    customerResDO.setError("Invalid Customer id "+customerReqDO.getId());
          }}else{
    customerEntity=new CustomerEntity();                    
    customerEntity.setName(customerReqDO.getName());
    customerEntity.setPhone(customerReqDO.getPhone());
    customerEntity.setEmail(customerReqDO.getEmail());

    //customerReqEntity.setFacebookID(customerReqDO.getFacebookID());
    customerEntity.setPassword(customerReqDO.getPassword());
    //customerReqEntity.setCredits(customerReqDO.getCredits());

    customerEntity =customerRepository.save(customerEntity);

            }if(null != customerEntity){
                customerResDO.setId(String.valueOf(customerEntity.getId()));
                customerResDO.setName(customerEntity.getName());
                customerResDO.setPhone(customerEntity.getPhone());
                customerResDO.setEmail(customerEntity.getEmail());
                customerResDO.setPassword(customerEntity.getPassword());
                //deliveryLocationResponseDO.setDeliverytimes(Arrays.asList(deliveryLocationEntity.getDeliverytimes()));
            }
    return customerResDO;

}



controller

@CrossOrigin（起源=＆＃34; *＆＃34;） @PostMapping（） public CustomerResponseDTO register（@RequestBody CustomerUpdateRequestDTO registerRequestDTO）{ CustomerDO customerReqDO = new CustomerDO（）; CustomerResponseDTO loginResponseDTO = new CustomerResponseDTO（）; customerReqDO.setName（registerRequestDTO.getName（））; customerReqDO.setEmail（registerRequestDTO.getEmail（））; customerReqDO.setPhone（registerRequestDTO.getPhone（））; customerReqDO.setPassword（registerRequestDTO.getPassword（））;

    CustomerDO  customerResDO = customerLoginManagerImpl.insert(customerReqDO);

    if(null != customerResDO.getError()){
        loginResponseDTO.setError(customerResDO.getError());
    }else{


    loginResponseDTO.setSucess(true);
}

    return loginResponseDTO;
}
