有什么建议如何解决吗？
如果正确配置了名称空间且XSD文件位于类路径中，则无需在schemaLocation URL中使用classpath：协议。
Spring doc“ 注册处理程序和模式 ”显示了应如何完成。
在你的情况下，问题可能出在你的类路径上的spring-context jar不是2.1。这就是将协议更改为类路径的原因：并将特定的2.1 XSD放在类路径中可以解决此问题。
从我所看到的，在spring- * jar中为主XSD定义了2个模式。一次使用版本解析模式URL，一次不使用版本解析模式URL。
例如，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
这意味着（在xsi：schemaLocation中）
http://www.springframework.org/schema/context/spring-context-2.5.xsd
将针对
org/springframework/context/config/spring-context-2.5.xsd
在类路径中。
http://www.springframework.org/schema/context/spring-context-3.0.xsd
要么
http://www.springframework.org/schema/context/spring-context.xsd
org/springframework/context/config/spring-context-3.0.xsd
http://www.springframework.org/schema/context/spring-context-2.1.xsd
未定义，因此Spring将使用schemaLocation中定义的文字URL进行查找。
