我的控制器：

@RequestMapping(value = "/api/rest")
@RestController
@RequiredArgsConstructor
@Validated
public class WarehouseController {
....

@GetMapping(path = "v2/warehouses/limited")
 public List<WarehouseSimpleListDto> getRestrictedWarehouses(
            @RequestParam(required = false, defaultValue = "{}") WarehouseSearchFilterSimpleDto filter
    ) {

我的 cucumber 测试：

Given I request GET at endpoint:
    """
    /api/rest/v2/warehouses/limited?filter={"shipper_ids":[333444]}
    """
    Then the response status code should be 200

其中：

import com.fasterxml.jackson.annotation.JsonProperty;
import lombok.Data;

import java.util.Set;

@Data
public class WarehouseSearchFilterSimpleDto {
    @JsonProperty("shipper_ids")
    private Set<Long> shipperIds;
    @JsonProperty("carrier_ids")
    private Set<Long> carrierIds;
}

这是怎么回事？我有非常相似的端点工作！当我改变过滤器dto的工作（相同！），然后它的确定。魔术对我来说
错误：

对象中的UPDATEMap只对String字段有效！

我不得不在我的项目中添加一些Map器：

@Component
@RequiredArgsConstructor
public class StringToWarehouseSearchSimpleDto implements Converter<String, WarehouseSearchFilterSimpleDto> {

    private final ObjectMapper objectMapper;

    @Override
    @SneakyThrows({IOException.class})
    public WarehouseSearchFilterSimpleDto convert(String source) {
        return objectMapper.readValue(source, WarehouseSearchFilterSimpleDto.class);
    }
}
