Spring cvc-elt.1：找不到元素'beans'的声明和类似的问题

Question

since some days I got this strange problem with spring 4.3.3 . On deploy (both in DEV and in a Test environment the server produces alternately these 2 errors

Error #1. It comes when I'm over a proxy or an internet connection is not available

Ignored XML validation warning: org.xml.sax.SAXParseException; lineNumber: 8; columnNumber: 108; schema_reference.4: Failed to read schema document 'http://www.springframework.org/schema/beans/spring-beans.xsd', because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not <xsd:schema>.

and then

 Context initialization failed: org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 8 in XML document from ServletContext resource [/WEB-INF/jboss-as-spring-mvc-context.xml] is invalid; nested exception is org.xml.sax.SAXParseException; lineNumber: 8; columnNumber: 108; cvc-elt.1: Cannot find the declaration of element 'beans'.

Error #2. It comes when a connection is available (or was available)

 JBWEB000289: Servlet pdaServlet threw load() exception: org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Unable to locate Spring NamespaceHandler for XML schema namespace [http://www.springframework.org/schema/context]

Offending resource: ServletContext resource [/WEB-INF/jboss-as-spring-mvc-context.xml]

Independently from the exception thrown the system WORKS anyway, probably due to the fact that the spring configuration is split in 3 files and the first 2 load correctly. But I'd like to understand what's happening. I've seen a LOT of responses on both these topics, but none applies to my case.

Here's my configuration:

which is correct (similar for infrastructure.xml). Instead this message when processing jboss-as-spring-mvc-context.xml

   23:47:24,360 DEBUG [org.springframework.beans.factory.xml.DefaultBeanDefinitionDocumentReader] (ServerService Thread Pool -- 23) Loading bean definitions
    23:47:24,361 DEBUG [org.springframework.beans.factory.xml.DefaultNamespaceHandlerResolver] (ServerService Thread Pool -- 23) Loaded NamespaceHandler mappings: {}

2- When having the error #2 if I change xmlns:context in xmlns:context2 in jboss-as-spring-mvc-context.xml , we fall back in the error #1 .

3- This spring configuration infrastructure (with the 3 files ) is shipped with JBOSS Development Studio as a Maven SPring Project

4- The same spring configuration infrastructure does not have these problems with other projects

I'd like to solve the issue, event if it does not have practical consequences

Answer 1

Looks like you missed a library with *.xsd files for one of used namespaces. Only in that case Spring will tries to load an xsd file from external url.
