沒有聲明可以發現元素「JPA：庫」

我建立一個簡單的Spring項目，並想在它配置JPA。我跟着這個教程：http://duckranger.com/2012/04/spring-mvc-3-x-with-sts-tutorial-part-iii-add-some-jpa/comment-page-1/#comment-3085 沒有聲明可以發現元素「JPA：庫」

現在我已經走到了盡頭，但是當我嘗試運行測試，根據我得到的錯誤如下教程：

這是確切的一部分在抱怨：

Caused by: org.xml.sax.SAXParseException: cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'jpa:repositories'. 
    at com.sun.org.apache.xerces.internal.util.ErrorHandlerWrapper.createSAXParseException(ErrorHandlerWrapper.java:195)

這是我的applicationContext.xml的樣子：

任何人都可以幫忙嗎？非常感謝。

爲了解決這個問題，在applicationContext.xml中的定義必須正確有序位置「春天上下文」之後的「TX」和「TX-春天」，則錯誤將得到解決。

在XML聲明頭包括以下行有春天數據存儲庫模式中聲明：

<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
     OTHER DEFINITIONS 
     xmlns:repository="http://www.springframework.org/schema/data/repository" 
     xsi:schemaLocation=" OTHERS 
     http://www.springframework.org/schema/data/repository 
     http://www.springframework.org/schema/data/repository/spring-repository.xsd"> 

</beans>

希望有所幫助。

的答覆非常感謝，其實是錯誤，是因爲定義命令，我剛纔放在「TX」和「TX-春天」「春天上下文」之後，現在我得到一種不同的錯誤的：致：org.springframework.beans.factory.BeanCreationException：錯誤創建名稱爲豆**「trampRepository」：持久性的依賴關係注入失敗; ** ..Cannot發現類[org.springframework.beans.factory.aspectj.AnnotationBeanConfigurerAspect用於與名稱豆「org.springframework.context.config.internalBeanConfigurerAspect」在空定義; – tokhi

我不知道你是怎麼保持的依賴關係，但我相信你缺少的依賴要麼'彈簧tx'或'彈簧aop'。 – nobeh

沒有聲明可以發現元素「JPA：庫」
