spring报找不到<task:executor标签约束?报错

是不是忘记加下面的这个了？

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

可以参考一下：

<?xmlversion="1.0"encoding="UTF-8"?><beansxmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:context="http://www.springframework.org/schema/context"xmlns:task="http://www.springframework.org/schema/task"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans-4.0.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context-4.0.xsdhttp://www.springframework.org/schema/taskhttp://www.springframework.org/schema/task/spring-task-4.0.xsd">。。。。。。</beans>

估计是上面这位仁兄说的这样
