Validation非Controller层验证

Validation非Controller层验证

直接上代码

public class ValidationUtils {

    private static final Validator validator;

    static {
        validator = Validation.buildDefaultValidatorFactory().getValidator();
    }

    /**
     * 校验对象
     *
     * @param object 待校验对象
     * @param groups 待校验的组
     * @throws IllegalArgumentException 校验不通过，则报业务异常
     */
    public static void validateEntity(Object object, Class<?>... groups) throws IllegalArgumentException {
        Set<ConstraintViolation<Object>> constraintViolations = validator.validate(object, groups);
        if (!constraintViolations.isEmpty()) {
            String msg = constraintViolations.stream().map(ConstraintViolation::getMessage).collect(Collectors.joining("、"));
            throw new IllegalArgumentException(msg);
        }
    }
}

该方法是非线程安全的多线程下慎用
