参考：ValidationUtils 参数校验

Bean 校验

java

import cn.com.digitalhainan.tools.ValidationUtils;

public void validateOrder(OrderCreateDTO dto) {
    ValidationUtils.ValidResult result = ValidationUtils.validateBean(dto);
    if (result.isHasErrors()) {
        throw BusinessException.error(
            XxxOfBusinessExceptionCodeEnum.ERR_INVALID_PARAMS,
            result.getErrors()
        );
    }
}

单个属性校验

java

public void validateEmail(String email) {
    ValidationUtils.ValidResult result = ValidationUtils.validateProperty(
        new UserDTO(email), "email"
    );
    if (result.isHasErrors()) {
        throw BusinessException.error(
            XxxOfBusinessExceptionCodeEnum.ERR_INVALID_PARAMS,
            result.getErrors()
        );
    }
}

ValidationUtils 基于 HibernateValidator，采用非快速失败模式（failFast = false），会收集所有校验错误后一并返回。
