cvc-complex-type.2.4.c：匹配的通配符是嚴格的，但是對元素的任務沒有聲明：註釋驅動

Question

我正在用Spring Framework 4.0.6編寫一個Web應用程序，我必須安排一個小例程，每天在同一時間運行。我通過使用@Scheduled註釋並在我的dispatcher-servlet.xml中添加標籤來嘗試它，但是當應用程序啓動時我得到一個SAXParseException。我的XML文件是這樣的：

<?xml version="1.0" encoding="UTF-8"?>

    <tx:annotation-driven transaction-manager="transactionManager"/> 
    <task:annotation-driven /> 

我得到的錯誤是下面：

預先感謝您的回答。

Answer 1

看這裏是一個錯誤：

xmlns:task="http://www.springframework.org/task/spring-task" 

所以，您嘗試使用一個名稱空間作爲spring-task同時它的位置是：

http://www.springframework.org/schema/task 

命名空間必須是完全一致的聲明位置。
