please advise why i am getting such exception in offline mode and how to fix it, thanks.
请告知为什么我在离线模式下遇到这种异常以及如何解决它，谢谢。

If you're using Spring 3.0.5, then you should be using the 3.0 schema, not the 3.1 schema. Spring validates your XML files against copies of the schema that it holds within its own JAR files, rather than copies it fetches from the internet.
如果您使用的是 Spring 3.0.5，那么您应该使用 3.0 模式，而不是 3.1 模式。Spring 根据它在自己的 JAR 文件中保存的模式副本来验证您的 XML 文件，而不是从 Internet 获取的副本。

Removing the specific version numbers should solve your problem.
删除特定版本号应该可以解决您的问题。

Inside the spring jars there is a spring.schemasfile that is used to map Spring Schema URIs to local copies packaged in the spring jars. Below is an example of a spring.schemasfile that was taken from the spring-beans jar (version 3.0.7.RELEASE). As you can see "spring-beans.xsd" is mapped to "spring-beans-3.0.xsd", which is the version of the jar.
在 spring jar 中有一个spring.schemas文件，用于将 Spring Schema URI 映射到打包在 spring jar 中的本地副本。下面是从 spring-beans jar（版本 3.0.7.RELEASE）中获取的spring.schemas文件的示例。正如你所看到的，“spring-beans.xsd”被映射到“spring-beans-3.0.xsd”，这是jar的版本。
This approach will assure that you are always using the correct schema version; upgrading your spring jars will automatically update your schemas.
这种方法将确保您始终使用正确的模式版本；升级您的 spring jar 将自动更新您的架构。

If you have Spring 3.0 then your schema declaration should be as follows (note version changed to 3.0):
如果您有 Spring 3.0，那么您的架构声明应如下（注意版本更改为 3.0）：

Even if the question has been already been fully addressed by skaffman's answerand mike's answer, I think that someone could find useful the case in which I found myself.
即使skaffman's answer和Mike's answer已经完全解决了这个问题，我认为有人会发现我发现自己的案例有用。
After having read, understood and applied the so reported answers my webapp wasn't still working. Well, this was my context (the relevant part):
阅读、理解并应用如此报告的答案后，我的 web 应用程序仍然无法正常工作。好吧，这是我的背景（相关部分）：
<beans xmlns="http://www.springframework.org/schema/security"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:beans="http://www.springframework.org/schema/beans"
xsi:schemaLocation="http://www.springframework.org/schema/security
http://www.springframework.org/schema/security/spring-security.xsd
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd">
I wanted the "security" as the default namespace... But I didn't add the prefix "beans:" to the root, and that was the problem. So the resulting right part of the context is:
我想要“security”作为默认命名空间……但我没有在根目录中添加前缀“beans:”，这就是问题所在。所以上下文的正确部分是：
<beans:beans xmlns="http://www.springframework.org/schema/security"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:beans="http://www.springframework.org/schema/beans"
xsi:schemaLocation="http://www.springframework.org/schema/security
http://www.springframework.org/schema/security/spring-security.xsd
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd">

The problem lies in the JAR that you use in your application. What I tried and what worked for me was to get copies of the versions of the JARs you are using (SPRING-CORE, SPRING-BEANS, SPRING-CONTEXT, SPRING-TX). Within the META-INF folder, concatenate all spring.schemas and spring.handlers files that are in those JARs. Kill two birds with one stone, solve the problem of the schemas, and it also works correctly in offline mode.
问题在于您在应用程序中使用的 JAR。我尝试过并且对我有用的是获取您正在使用的 JAR 版本的副本（SPRING-CORE、SPRING-BEANS、SPRING-CONTEXT、SPRING-TX）。在 META-INF 文件夹中，连接这些 JAR 中的所有 spring.schemas 和 spring.handlers 文件。一石二鸟，解决了schema的问题，离线模式下也能正常使用。

when running application in offline mode (no internet connection), BTW everything works fine when there's an internet connection, any ideas why ?
在离线模式下运行应用程序时（没有互联网连接），顺便说一句，当有互联网连接时，一切正常，为什么？
For what it's worth, this also happens when your eclipse WST cache holds a 404 error page and WST is performing the XML validation against this HTML page instead of the real XSD schema definition.
值得一提的是，当您的 eclipse WST 缓存包含 404 错误页面并且 WST 正在针对此 HTML 页面而不是真正的 XSD 模式定义执行 XML 验证时，也会发生这种情况。
To address this case, Windows => preferences => General => Network => Cacheand remove the offending cached resource.
为了解决这种情况，Windows => preferences => General => Network => Cache并删除有问题的缓存资源。

This worked for me:
Need to change the default namespace like below:

Worked :
工作过：

context.load("myResource.xml");
context.refresh();
Not worked:
没有工作：
ClassPathXmlApplicationContext ctx = new
