春天宁静的网络服务验证

Question

我遇到了一个问题，如何在json中验证空输入？

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;
    }

我想要的只是验证customerId和srctable不是空值，这是我的dto

@Entity
@Table(name="all_customer_hist")

}

我的目标是，当这个json抛出时：

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

它应该返回消息，通知消费者srctable和customerId不能为null，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null。

谢谢，等待你的帮助：D

Answer 1

是时候介绍DTO（数据传输对象）并在控制器中使用它。猜猜你不需要一些领域，例如实体的lastUpdatedDate未在搜索逻辑中使用。

您需要添加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进行注释。您可能还需要转换器，以便在必要时将DTO转换为实体。

Answer 2

使用@Valid中的javax.validation.Valid @NotNull注释。

另外，我想建议一个博客用于其他API验证here。
