java – 无法找到XML模式命名空间的Spring NamespaceHandler [http://www.springframework.org/schema/data/jpa]

org.springframework.beans.factory.parsing.BeanDeFinitionParsingException:
Configuration problem: Unable to locate Spring NamespaceHandler for
XML schema namespace [http://www.springframework.org/schema/data/jpa]
Offending resource: ServletContext resource
[/WEB-INF/spring/appServlet/servlet-context.xml]

这是我的’servle-context.xml'(缩进有一些问题,但是文件太大了……)：
