第一步：定义ValidationResult类

public class ValidationResult {

    // 校验结果是否有错

    private boolean hasErrors = false;

    // 存放错误信息的Map

    private Map<String, String> errorMsgMap = new HashMap<>();

    public boolean isHasErrors() {

        return hasErrors;

    }

    public void setHasErrors(boolean hasErrors) {

        this.hasErrors = hasErrors;

    }

    public Map<String, String> getErrorMsgMap() {

        return errorMsgMap;

    }

    public void setErrorMsgMap(Map<String, String> errorMsgMap) {

        this.errorMsgMap = errorMsgMap;

    }

    // 实现通用的 通过格式化字符串信息获取 所有错误结果的Message方法

    public String getErrorMsg(){

        return StringUtils.join(errorMsgMap.values().toArray(), ",");

    }

}

第二步：定义ValidatorImpl实现类

/**

 * InitializingBean接口为bean提供了初始化方法的方式，它只包括afterPropertiesSet方法，凡是继承该接口的类，在初始化bean的时候都会执行该方法。

 * Spring初始化完成后，会回调ValidatorImpl的afterPropertiesSet()方法

 */

@Component

public class ValidatorImpl implements InitializingBean {

    private Validator validator;

    // 实现校验方法并返回校验结果

    public ValidationResult validate(Object bean){

        ValidationResult validationResult = new ValidationResult();

        Set<ConstraintViolation<Object>> constraintViolationSet = validator.validate(bean);

        if(constraintViolationSet.size() > 0){

            // 大于0 表示有错误

            validationResult.setHasErrors(true);

            for (ConstraintViolation<Object> constraintViolation : constraintViolationSet) {

                String errorMsg = constraintViolation.getMessage();

                String propertyName = constraintViolation.getPropertyPath().toString();

                validationResult.getErrorMsgMap().put(propertyName, errorMsg);

            }

        }

        return validationResult;

    }

    @Override

    public void afterPropertiesSet() throws Exception {

        // 将hibernate validator通过工厂的初始化方式使其实例化

        validator = Validation.buildDefaultValidatorFactory().getValidator();

    }

}

第三步，在业务逻辑中调用

public class UserModel {

    private Integer id;

    @NotBlank(message = "name不能为空")

    private String name;

    @NotNull(message = "性别不能为空")

    private Byte gender;

    @NotNull(message = "年龄不能为空")

    @Min(value = 0, message = "年龄必须小于0")

    @Max(value = 150, message = "年龄不能大于150")

    private Integer age;

    @NotNull(message = "手机号码不能为空")

    @Size(min = 11, max = 11, message = "手机号码必须为11位")

    private String telphone;

    @NotNull(message = "注册方式不能为空")

    private String registerMode;

    private String thirdPartyId;

    @NotNull(message = "密码不能为空")

    private String encrptPassword;

    @Autowired

    private ValidatorImpl validator;

    @Transactional

    public void register(UserModel userModel) throws BusinessException {

        if(userModel == null){

            throw new BusinessException(EnumBusinessError.PARAMETER_VALIDATION_ERROR);

        }

        //

        ValidationResult validationResult = validator.validate(userModel);

        if(validationResult.isHasErrors()){

            throw new BusinessException(EnumBusinessError.PARAMETER_VALIDATION_ERROR, validationResult.getErrorMsg());

        }
