spring - 为什么 Spring XSD 会出现 DTD 错误 "White spaces are required between publicId and systemI"

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，我看到:

            White spaces are required between publicId and systemId

根据遇到此问题的其他人的说法，它与显然必须具有 SYSTEM 标识符的 DOCTYPE 有关。

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

你必须将 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">
