java - 错误: validation failed for objects with date

Question

使用 spring 我有这个端点，

@RequestMapping(value = "/time/{date}", method = RequestMethod.GET)
public ModelRunCollection getPolicyByDate(GetPolicyByDateRequest request) {
    return delegate.submit(request);
}

请求对象如下所示

@Getter
@Setter
public class GetPolicyByDateRequest {

    @DateTimeFormat(pattern = "YYYY-MM-DDTHH:mm:ss.sssZ")
    private DateTime date;

    public GetPolicyByDateRequest date(DateTime date) {
        this.date = date;
        return this;
    }
}

我点击的网址是这个

http://localhost:8080/time/2020-01-17T00:33:53.148Z

我得到的错误是

对象='getCreditPolicyByDateRequest'的验证失败。错误计数:1

我一直无法理解为什么这是一个问题。我查看了这个解决方案，但似乎正在做他提到的确切事情

Spring Validation failed for object with date field

Answer 1

你可以尝试这样做。在获取请求中仅传递日期。稍后您就可以在类里面通过它。

@RequestMapping(value = "/time/{date}", method = RequestMethod.GET)
public ModelRunCollection  getPolicyByDate(
        @PathVariable("date")
        @DateTimeFormat(pattern = "yyyy-MM-dd'T'HH:mm:ss.SSS'Z'")
                DateTime date) {
    return delegate.submit(new GetPolicyByDateRequest(date));
}
