Question

我有一个奇怪的错误，我在互联网上搜索了很多。我无法理解为什么我收到此错误。我在春季jira上找到了关于这个错误的一些解释。我在context:component-scan中有applicationContext.xml，我在com.sow.webservices包中定义了5个包。但是，当我添加包含控制器类的控制器包时，我抛出

Error occured processing XML '[Ljava.lang.String; cannot be cast to java.lang.String'. See Error Log for more details

这是组件扫描：

<context:component-scan base-package="com.sow.webservices.aop, 
                                          com.sow.webservices.exceptions,
                                          com.sow.webservices.models, 
                                          com.sow.webservices.services,
                                          com.sow.webservices.controller">

我想向您展示整个异常跟踪。感谢您的帮助。

即使xml抛出此异常，我也可以运行我的应用程序，但是当我删除com.sow.webservices.controller时，它会停止显示有错误符号，但它会出现404错误。由于我遇到组件扫描问题，LocaleChangeInterceptor无法正常工作，我无法将我的应用程序国际化

检查你的控制器，如果其中一个使用注释@ControllerAdvice尝试注释掉它，奇怪的是错误消失了。 FREAKY !!!!
