任何想法，什么可能导致此错误？

org.springframework.beans.factory.parsing.BeanDefinitionParsingException：配置问题：无法找到XML架构命名空间的Spring NamespaceHandler [http://www.springframework.org/schema/data/jpa]攻击资源：ServletContext资源[/ WEB -INF / spring / appServlet / servlet的context.xml中]

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

如您所见，我指定了jpa-schema的路径 . 我不知道是什么问题

java spring maven-3

    尝试更换

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

    通过

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

    但是，如果您仍然使用版本1.0-M1，请先尝试更新 . DATAJPA-21

    确保您的依赖项中有spring-data-jpa

    如果你使用maven：

    <dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-jpa</artifactId>
    <version>1.7.0.RELEASE</version>
</dependency>

    问题是因为无法找到spring-jpa架构 . 您可能正在使用一些不包含架构信息的旧jar .

    我知道这看起来很傻，但是如果你使用的是IDEA和Maven，你应该检查以确保你已经检查了使用插件注册表，这样服务器也可以访问你的jar文件 .

    我会发布一个屏幕截图，但我是新来的，没有足够的声望点 . 它确实有效，我已经与IntelliJ的支持团队进行了验证

    在一周内遇到同样的问题后，我找到了解决方案 . 如果您使用的是Spring MVC JPA Maven，请使用此dispatcher-servlet.xml
