我有一个Spring MVC应用程序，配置如下：
<context:component-scan base-package="com.mkyong.controller">
<context:exclude-filter type="regex"
expression="com.mkyong.controller.Movie.*" />
</context:component-scan>
<mvc:annotation-driven />
<!-- Bean to show you Di in GAE, via Spring, also init the MovieController -->
<bean class="com.mkyong.controller.MovieController">
<property name="message">
<value>Hello World</value>
</property>
</bean>
<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix">
<value>/pages/</value>
</property>
<property name="suffix">
<value>.jsp</value>
</property>
</bean>
</beans>
我在WEB-INF / lib目录中都需要JAR。这会引发以下错误（发布完整堆栈跟踪）：

看来你在WEB-INF / lib中没有spring-beans jar。你可以将这个jar添加到类路径并重试。如果它不起作用，你可以在WEB-INF / lib中发布完整的jar列表。
要查找哪个jar包含给定的缺失类，请使用grepcode.com等网站进行检查，例如这是包含FatalBeanException的jar报告。

我遇到了这个问题，这是因为被测试的类是一个独立的Java程序，它带有一个main（）方法和一个构造函数，它使用以下方法显式实例化Spring上下文：
context = new ClassPathXmlApplicationContext("applicationContext.xml");
...并且它用＆＃39; @Component＆＃39;进行了注释。因此，当执行上述语句时，Spring会扫描包中的注释类，并尝试重新实例化当前正在构造的相同类。我通过删除注释来修复它。
我没有解释堆栈跟踪，它抱怨它无法找到Exception类，除了可能，当Spring正在进行其上下文构建时，类路径与主类的路径不同，并且此类路径不包含org.springframework.beans。
