我有一個表客戶和 2 列 customer_id 和 customer_name。我想用json發送id列表請求并返回相應的客戶名稱。但我無法處理 dto 對象和控制器服務架構。輸入dto：public class CustomerSearchDto extends BaseDto {    @ApiModelProperty(            example = "1",            value = "Customer Id",            required = true,            dataType = "Long"    )    private Long id;}輸出到：public class CustomerDto extends BaseDto {    private Long id;    private String name;    public Long getId() {        return id;    }    public void setId(Long id) {        this.id = id;    }    public String getName() {        return name;    }    public void setName(String name) {        this.name = name;    }}控制器類：@ApiOperation(            value = "Return Customer",            response = Customer.class    )    @PostMapping(value = Endpoint.RRESOURCE_CUSTOMER_GROUP_BY_ID)    public ResponseEntity<CustomerDto> getCustomersById(@RequestBody @Validated CustomerSearchDto CustomerSearchDto) {        CustomerDto CustomerDto = new CustomerDto;        List<CustomerDto> CustomerDtoList = CustomerService.findCustomerByIds(ids);        return ResponseEntity.ok(CustomerDto);    }服務類方法：@Transactional    public List<CustomerDto> findCustomerByIds(List<Long> customerIds) {        List<Customer> customerList = repository.findCustomerById(CustomerIds);        return mapper.mapAsList(CustomerList, CustomerDto.class);    }控制器類中有一些錯誤。而且我不確定我是否應該為輸入和輸出定義不同的 dto 類？
