spring boot kotlin validate问题

#kotlin #springboot

背景 

@ApiModelProperty(value = "markdown原始内容", required = true) @NotBlank(message = "markdown内容不能为空") var md: String? = "",
Enter fullscreen mode Exit fullscreen mode

验证不生效，需要修改一下

@ApiModelProperty(value = "markdown原始内容", required = true) @field:NotBlank(message = "markdown内容不能为空") var md: String? = "",
Enter fullscreen mode Exit fullscreen mode

统一返回错误，可以针对不的异常类型进行捕获，比如

 @ExceptionHandler(BindException::class) @ResponseStatus(HttpStatus.BAD_REQUEST) @ResponseBody fun handle(e: BindException): R<Any> { val err = e.bindingResult.fieldErrors val msg = err[0].defaultMessage return R.fail(9005, msg ?: "未知错误") }
Enter fullscreen mode Exit fullscreen mode
