Spring Boot 验证消息未显示

Yun*_*unz 6 java validation spring kotlin spring-boot

我有一个 Spring Boot 应用程序(版本 2.4.5)作为 Kotlin 项目。现在,当我输入无效内容时,我会收到一条错误消息,但不是我在注释中设置的错误消息。

控制器

  @PostMapping(value = ["/seatMap/save"])
    fun addSeatPlan(@RequestPart @Valid data: DSeatMap, @RequestPart image: MultipartFile?, auth: AuthenticationToken) {
        try {
            if (data.uuid == null) {
                seatService.addSeatMap(auth.organisation!!, data, image)
            } else {
                seatService.updateSeatMap(data, auth.organisation!!, image)
            }
        } catch (e: UnauthorizedException) {
            throw e
        }
    }

数据类

import java.util.*
import javax.validation.constraints.NotEmpty

data class DSeatMap(
    var uuid: UUID?,
    @field:NotEmpty(message = "name is empty")
    val name: String,
    var data: String,
    val quantity: Int,
    var settings: DSettings?

我的回复,这里应该是消息=“名称为空”

{
  "timestamp": "2021-04-22T19:47:08.194+00:00",
  "status": 400,
  "error": "Bad Request",
  "message": "Validation failed for object='data'. Error count: 1",
}

如果我设置该属性,它会显示正确的属性,但我不想获得所有辅助信息,我只想输出消息

server.error.include-binding-errors=always

结果:

好吧,我终于找到了解决方案。我创建了一个监听 MethodArgumentNotValidException 的全局异常处理程序。之后,我操作该消息并设置我之前在注释中设置的验证消息

@RestControllerAdvice
class ExceptionControllerAdvice {

    @ResponseStatus(HttpStatus.BAD_REQUEST)
    @ExceptionHandler(MethodArgumentNotValidException::class)
    fun handleValidationExceptions(ex: MethodArgumentNotValidException): Map<String, String?>? {
        val errors: MutableMap<String, String?> = HashMap()
        ex.bindingResult.allErrors.forEach { error: ObjectError ->
            val fieldName = (error as FieldError).field
            val errorMessage = error.getDefaultMessage()
            errors[fieldName] = errorMessage
        }
        return errors
    }

}

@Yunz我认为“错误”属性会添加到您的响应中,因为您设置了 server.error.include-binding-errors=always您可以尝试将其设置为never或不定义此属性并依赖默认值(即never)。

需要设置server.error.include-message=always从2.3版本开始,Spring Boot隐藏响应中的message字段,避免泄露敏感信息;我们可以使用带有always值的这个属性来启用它
