定制弹簧验证器

Question

我创建了皮肤验证器，但有一个问题。当我收到错误消息时，我可以看到：

status": 400,
"error": "Bad Request",
"errors": [
    {
        "codes": [
            "ValidHours.loginHoursRequest.startHour",
            "ValidHours.startHour",
            "ValidHours.java.lang.String",
            "ValidHours"
        ],
        "arguments": [
            {
                "codes": [
                    "loginHoursRequest.startHour",
                    "startHour"
                ],
                "arguments": null,
                "defaultMessage": "startHour",
                "code": "startHour"
            }
        ],
        "defaultMessage": "Invalid",
        "objectName": "loginHoursRequest",
        "field": "startHour",
        "rejectedValue": "1330",
        "bindingFailure": false,
        "code": "ValidHours"
    }
],
"message": "Validation failed for object='loginHoursRequest'. Error count: 1"

现在，我只想接收“ defaultMessage”，因此它应该是类似的：

status": 400,
"error": "Bad Request",
"errors": "defaultMessage": "Invalid"

我的有效课程：

@MustBeDocumented
@Constraint(validatedBy = [HoursValidation::class])
@Target(
    AnnotationTarget.FIELD, AnnotationTarget.FUNCTION)
@Retention(AnnotationRetention.RUNTIME)
@ReportAsSingleViolation
annotation class ValidHours(
    val message: String = "Invalid",
    val groups: Array<KClass<out Any>> = [],
    val payload: Array<KClass<out Payload>> = []
     )
