任何建议如何解决？

如果正确配置了命名空间并且XSD文件位于类路径中,则无需在schemaLocation URL中使用classpath:protocol.

Spring doc" 注册处理程序和模式 "显示了它应该如何完成.

在您的情况下,问题可能是类路径上的spring-context jar不是2.1.这就是为什么将协议更改为类路径:并将特定的2.1 XSD放在类路径中解决了问题.

从我所看到的,为spring-*jar中包含的主XSD定义了2个模式.一旦用版本解析架构URL,一旦没有它.

作为示例,请参阅spring-context-3.0.5.RELEASE.jar中spring.schemas内容的这一部分:

http\://www.springframework.org/schema/context/spring-context-2.5.xsd=org/springframework/context/config/spring-context-2.5.xsd
http\://www.springframework.org/schema/context/spring-context-3.0.xsd=org/springframework/context/config/spring-context-3.0.xsd
http\://www.springframework.org/schema/context/spring-context.xsd=org/springframework/context/config/spring-context-3.0.xsd

未定义,因此Spring将使用schemaLocation中定义的文字URL查找它.

  • 对于那些需要摘要的人:Spring无法在类路径中找到模式.Spring核心JAR具有包含在JAR中的模式 - >文件名映射.如果它无法解决这个问题,它将进入网络. (35认同)
  • @Stormcloud,是的,原来的链接似乎又回来了,我建议破坏了.这是最新的文档链接:http://docs.spring.io/spring/docs/current/spring-framework-reference/html/xml-custom.html#extensible-xml-registration (2认同)

classpath:spring-context-2.1.xsd是离线模式工作的关键(没有互联网连接).我还复制spring-context-2.1.xsd了application-context.xml文件附近(相同目录)

  • 对于可能遇到此问题的intellij用户.即使intellij无法识别schemalLocation中的类路径语法并将其突出显示为错误,这仍然有效. (6认同)

如果有人通过我所做的同一个根到达这里 - 我遇到了这个问题,因为我正在构建一个包含所有依赖项的JAR,包括Spring JAR.结果,Spring JAR的某些META-INF目录中的spring.schemas文件被覆盖.

我在这里找到了建议的解决方案:如何使用maven创建基于spring的可执行jar？

今天遇到类似的问题.在我的情况下,除了springframework.org中断之外,它是阴影插件的罪魁祸首.以下片段清理了一些内容:

<transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
   <resource>META-INF/spring.schemas</resource>

<transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
