Java Spring 3.2泛型类型的验证

我有一个界面，如下所示：

@Validated
public interface Service<T extends Foo, N extends Bar> {
    @Valid
    @NotNull
    T doStuff(@Valid N bar);
}

最后，我基本上有一个实现PhoneService的控制器，例如：

@Controller
public final class PhoneServiceController implements PhoneService {
    @RequestMapping(...)
    @Override
    @ResponseBody
    PhoneFoo doStuff(@RequestBody final PhoneBar bar) {
        // Do things...
    }
}

现在，控制器上的验证根本不起作用。我可以输入一个空id或一个空号码，并且不会引发任何异常。 Spring在验证泛型类型方面有什么特别的事情要做吗？有解决办法吗？用Spring boot解决了这个问题吗

编辑： 我还定义了以下bean，以便Spring能够在验证时进行处理：

@Bean
public static MethodValidationPostProcessor methodValidationPostProcessor() {
    MethodValidationPostProcessor postProcessor = new MethodValidationPostProcessor();
    postProcessor.setProxyTargetClass(true);
    postProcessor.setValidator(validator());
    return postProcessor;
}

@Bean
public static Validator validator() {
    HibernateValidatorConfiguration configuration = (HibernateValidatorConfiguration) Validation
            .byDefaultProvider().configure();
    return configuration
            .messageInterpolator(
                    new ValueFormatterMessageInterpolator(configuration
                            .getDefaultMessageInterpolator())).buildValidatorFactory()
            .getValidator();
}

注意：在我引入通用接口之前，我的项目中的验证工作正常。在我看来，Spring不知道如何处理有效的N条。还是我错了？

要向服务方法添加验证，您需要添加MethodValidationPostProcessor的实例

@Bean
@ConditionalOnMissingBean(type = "javax.validation.Validator")
public LocalValidatorFactoryBean localValidatorFactoryBean() {
    return new LocalValidatorFactoryBean();
}

@Bean
@Autowired
@ConditionalOnMissingBean(type = "org.springframework.validation.beanvalidation.MethodValidationPostProcessor")
public MethodValidationPostProcessor methodValidationPostProcessor(Validator validator) {
    MethodValidationPostProcessor methodValidationPostProcessor = new MethodValidationPostProcessor();
    methodValidationPostProcessor.setValidator(validator);
    return methodValidationPostProcessor;
}

@请参见

您是如何实例化/访问它们的？我编辑了这个问题，以说明我如何使用我的对象。您能让它工作吗？

@Bean
public static MethodValidationPostProcessor methodValidationPostProcessor() {
    MethodValidationPostProcessor postProcessor = new MethodValidationPostProcessor();
    postProcessor.setProxyTargetClass(true);
    postProcessor.setValidator(validator());
    return postProcessor;
}

@Bean
public static Validator validator() {
    HibernateValidatorConfiguration configuration = (HibernateValidatorConfiguration) Validation
            .byDefaultProvider().configure();
    return configuration
            .messageInterpolator(
                    new ValueFormatterMessageInterpolator(configuration
                            .getDefaultMessageInterpolator())).buildValidatorFactory()
            .getValidator();
}

@Bean
@ConditionalOnMissingBean(type = "javax.validation.Validator")
public LocalValidatorFactoryBean localValidatorFactoryBean() {
    return new LocalValidatorFactoryBean();
}

@Bean
@Autowired
@ConditionalOnMissingBean(type = "org.springframework.validation.beanvalidation.MethodValidationPostProcessor")
public MethodValidationPostProcessor methodValidationPostProcessor(Validator validator) {
    MethodValidationPostProcessor methodValidationPostProcessor = new MethodValidationPostProcessor();
    methodValidationPostProcessor.setValidator(validator);
    return methodValidationPostProcessor;
}
