Struts 2验证w /注释获取空异常 [英] Struts 2 Validation w/ annotations getting a null exception

问题描述

我们正在尝试使用Struts 2 Validation w / Annotations，我们遇到了一个奇怪的问题。我们有一个方法，我们已经指定了一个字符串验证。当我们运行该方法时，我们在第580行的AnnotationValidationConfigurationBuilder中得到一个NullException。我们看了看，验证Factory为null。我们追溯到后面，并且找不到为什么它将为null的原因，尽管我们注意到setValidatorFactory上的@Inject注释。

作为附注，我们也在组合中使用Spring 2，并从jQuery插件中调用它。

<有人有人遇到过吗？我们已经查看了所有的文档，没有人谈到需要使用Spring注册一个bean或者这样的东西。

谢谢，

Shane

解决方案

我们找到了答案。显然，如果您有一个validators.xml，则需要指定base validators.xml中的所有内容。自从我们过去使用这个以来，这种情况已经改变了，而不需要这样做。

We're trying to use Struts 2 Validation w/ Annotations and we've ran into a weird problem. We have a method that we have specified a string validation for. When we run that method we get a NullException in the AnnotationValidationConfigurationBuilder on line 580. We took a look and it appears that the validationFactory is null. We traced that back and can't find a reason why it would be null though we did notice an @Inject annotation on the setValidatorFactory.

As a side note we're also using Spring 2 in the mix and calling it from the jQuery plugin.

Has anyone run into this before? We've looked at all the docs and none of them talk about needing to register a bean with Spring or anything like that.

Thanks,

Shane

解决方案

We found the answer. Apparently if you have a validators.xml you need to specify everything in the base validators.xml. This has changed since we used this in the past without needing to do this.
