java - Spring MVC 中的 Autowiring ViewResolver

Question

由于某种原因，我无法 Autowiring ViewResolver:

@Component
public class JsonMultipleViewFactory
{
    @Autowired
    private ViewResolver viewResolver;

    // ...
}

viewResolver 为 null。

类JsonMultipleViewFactory在Spring Controller 中 Autowiring :

@Controller
public class HomeController
{
    @Autowired
    private JsonMultipleViewFactory jsonMultipleViewFactory;

    // ...
}

我创建了一个 github repository包含一个重现问题的很小的例子。

有人可以帮助我吗？

谢谢。

我的回答是your previous question ，没有答案:

In your example, JsonMultipleViewFactory is discovered through component scanning by parent context (applicationContext.xml). InternalResourceViewResolver is defined in child context (test-servlet.xml). So, is normal that parent context can't see beans defined in child context. This is the reason why you get a NoSuchBeanDefinitionException. Try to put all this beans in the same context.
