Question

我在Android上使用bean验证时遇到问题。我已将验证api和hibernate验证器4.0.1包含在libs和assets文件夹中。验证输入的代码如下

/* This doesn't work either
 * 
 * ValidatorFactory factory = Validation
 *      .byProvider(HibernateValidator.class).configure()
 *      .buildValidatorFactory();
 */

    ValidatorFactory factory = Validation.buildDefaultValidatorFactory();

    Validator validator = factory.getValidator();
    Set<ConstraintViolation<Class<Department>>> violations = validator
            .validate(Department.class);

    for (ConstraintViolation<Class<Department>> v : violations) {
        // do something useful
    }

我收到一个ValidationException，它声明没有找到默认提供程序。评论部分也不起作用。它还抛出一个ValidationException，声明它无法找到提供者org.hibernate.validator.HibernateValidator。

配置时我错过了什么吗？或者hibernate不适用于android？

更新

我尝试实现ValidatorProviderResolver为@Gunnar建议。代码更改为：

HibernateValidatorConfiguration config = Validation
            .byProvider(HibernateValidator.class)
            .providerResolver(new MyAndroidValidationProviderResolver())
            .configure();
ValidatorFactory factory = config.buildValidatorFactory();
Validator v = factory.getValidator();

现在我得到的例外情况如下：

02-05 20:21:36.642: E/AndroidRuntime(792): Caused by: java.lang.IllegalArgumentException: Invalid logger interface org.hibernate.validator.internal.util.logging.Log (implementation not found)

我还切换到Hibernate 5.0.3 final，包括所有库（必需和可选）。

Answer 1

org.hibernate.validator.internal.util.logging.Log接口使用Android不支持的2个类： javax.xml.bind.JAXBException和javax.xml.stream.XMLStreamException。这就是没有加载课程的原因。

验证异常：无法找到默认提供程序Android
