搭建完SpringMVC后要开启定时任务，添加以下：

xmlns:task="http://www.springframework.org/schema/task"

http://www.springframework.org/schema/task
http://www.springframework.org/schema/task/spring-task-3.2.xsd

<task:annotation-driven />
<!-- 配置自动扫描的包 -->
    <context:component-scan base-package="com.xxx"></context:component-scan>

添加了之后，启动报错如下：

Error creating bean with name 'org.springframework.context.annotation.internalAsyncAnnotationProcessor': 
Initialization of bean failed; nested exception is java.lang.NoClassDefFoundError: org/aopalliance/aop/Advice

警告: Exception encountered during context initialization - cancelling refresh attempt
