spring - 收到错误消息，找不到元素 'jpa:repositories' 的声明

Question

我收到以下错误

Line 84 in XML document from class path resource [car-job-app-context.xml] is 
invalid; nested exception is org.xml.sax.SAXParseException; lineNumber: 84; 
columnNumber: 154; cvc-complex-type.2.4.c: The matching wildcard is strict, but
no declaration can be found for element 'jpa:repositories'.

这是我的文件

.....

<context:annotation-config/>

<context:component-scan base-package="pk.training.basitMahmood.service.impl" />

<jpa:repositories base-package="pk.training.basitMahmood.repository" entity-manager-factory-ref="emf" transaction-manager-ref="transactionManager" />

这是我的 maven 依赖项的快照

我还看到了相同的链接，上面写着将 tx declaration 移到 context 之后，但它不起作用。 same post as my question .我试过前后组合，但错误仍然存​​在。

为什么我会收到这个错误？我无法在数据库中保存数据....？

谢谢

命名空间的顺序无关紧要。确保 spring-data-jpa 工件在您的类路径中，并仔细检查架构版本。没有 spring-jpa-2.0 这样的东西。它应该介于 1.0 和 1.3 之间。使用 Spring，您通常也可以省略版本并默认获取最新的模式。
