org.springframework.beans.factory.parsing.BeanDefinitionParsingException: 配置问题:无法找到Spring NamespaceHandler用于 XML模式名称空间[http://www.springframework.org/schema/data/jpa] 令人反感的资源:ServletContext资源 [/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...):

Here is my 'servle-context.xml' (there are some problems with the indents, but the file is too huge...):

如您所见，我指定了jpa-schema的路径.而且我不知道出了什么问题

As you can see, i specified the path to the jpa-schema. And I don't know what is the problem

推荐答案

尝试替换

http://www.springframework.org/schema/data/jpa/spring-jpa.xsd

作者

http://www.springframework.org/schema/data/jpa/spring-jpa-1.0.xsd

但是，如果您仍然使用1.0-M1版本，请尝试先进行更新. DATAJPA-21

But if you still use Version 1.0-M1 then try to update first. DATAJPA-21
