为什么Spring XSD会出现DTD错误“publicId和systemID之间需要空格”

Question

在我的应用程序上下文文件中，Eclipse 显示错误：

引用的文件包含错误 (http://www.springframework.org/schema/integration)。 applicationContext.xml 第 1 行 XML 问题

查看 Eclipse 中的错误详细信息：

            White spaces are required between publicId and systemId

据其他有此问题的人说，它与 DOCTYPE 有关，显然必须有一个 SYSTEM 标识符。

为什么在 2014 年 DOCTYPE 已经过时了，因为我们都使用 XSD 而不是 DTD，并且http://www.springframework.org/schema/integration 中没有 DOCTYPE（或者应该有）会发生此错误吗？

您必须将spring-context.xsd 移动到它的id：

<beans 
http://www.springframework.org/schema/jee 
http://www.springframework.org/schema/jee/spring-jee-2.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/integration
http://www.springframework.org/schema/integration/spring-integration-3.0.xsd">
