春季MVC:注释驱动的java.lang.noclassdeffounderror:javax/servlet/asyn

Question

我已经开发了一个带有弹簧3.0的应用程序，该应用程序正常。

当我将其包含在配置文件中时，我需要使用<mvc:annotation-driven/>的某些功能。

以下是我使用过的代码和错误：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context" 
xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd

http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd 
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-3.0.xsd">
    <mvc:annotation-driven />
......
</beans>

如果使用上下文：component-scan "尝试更改它。添加到base-package "。*" 作为样本：

"<context:component-scan base-package="controller.*/>"
