Spring RESTful Web 服务验证

Question

我遇到一个问题，如何验证 json 中的 null 输入？

这是我的代码：

    @RequestMapping(value="/findAdpId/", method=RequestMethod.POST , consumes = "application/json", produces = "application/json")
    public @ResponseBody String findAdpId(@RequestBody AllCustomerHist customer){
        String customerId = customer.getCustomerId();
        String srctable = customer.getSrctable();
        String message;

        System.out.println("customer ID = "+customerId);
        System.out.println("srctable = "+srctable);

//      List<AllCustomerHist> adpcust = allCustomerHistService.findAdpId(customerId, srctable);
        BigDecimal adpcust = (BigDecimal) allCustomerHistService.findAdpId(customerId, srctable);


        JSONObject json = new JSONObject();
        json.put("adpId", adpcust);

        message = json.toString();
        return message;
    }

我只想验证 customerId 和 srctable 不是空值，这是我的 dto

    }
}

我的目标是，当这个 json 被抛出时：

{
    "srctable":null,
    "customerId":null
    }

它应该返回消息，告知消费者 srctable 和 customerId 不能为空，但我不想在我的 dto 中添加 @NotNull，因为 customerId 和 srctable 对于其他进程可能为空。

谢谢你，等待你的帮助：D

Answer 1

是时候引入 DTO（Data Transfer Object）并在控制器中使用它了。猜猜您不需要某些字段，例如实体的 lastUpdatedDate 未在搜索逻辑中使用。

您需要添加一个带有必要字段的自定义 POJO，并使用 @NotNull 和所有其他必要的验证检查对其进行注释。您可能还需要一个转换器，以便在必要时将 DTO 转换为实体。

Answer 2

将javax.validation.Valid 中的@Valid 与@NotNull 注释一起使用。

另外，我想推荐一篇博客来验证REST API here。
