You can use validation group, and @Validated annotation.

有在 HTTP一个细节的解释：//www.java$c$cgeeks.com/2014/08/validation-groups-in-spring-mvc.html

该方法是基于<一个href=\"https://docs.jboss.org/hibernate/validator/4.1/reference/en-US/html/validator-usingvalidator.html#validator-usingvalidator-validationgroups\"相对=nofollow> Hibernate验证团体以及它使您能够将验证基于标记接口上并将其应用在处理器的水平，例如在链接给

The approach is based on hibernate validator's groups and it enables you to group the validation based on the marker interface and apply it on handler level, example as given in the link

@RequestMapping(value = "stepTwo", method = RequestMethod.POST)
public String stepTwo(@Validated(Account.ValidationStepTwo.class) Account account, Errors errors) {
  if (errors.hasErrors()) {
      return VIEW_STEP_TWO;
  }
  return "redirect:summary";
}
