Spring XSD's access error
提问by claudioivp
I'm trying to run a system left by an ex-employee here in my job, but I'm having problems to do it.
我正在尝试运行一个前雇员在我的工作中留下的系统，但我在做这件事时遇到了问题。
If the XSD runs by remote access:
如果 XSD 通过远程访问运行：
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:aop="http://www.springframework.org/schema/aop"

http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx.xsd">
It gives an not found exception:
它给出了一个未找到的异常：
Failed to read schema document 'http://www.springframework.org/schema/context/spring-context-3.0.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 if the XSD runs by local access:
如果 XSD 通过本地访问运行：
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:aop="http://www.springframework.org/schema/aop"

It gives this exception:
它给出了这个例外：

Some idea to solve this problem?

The Spring XDSs are defined and shipped with the Spring jars! For Example the spring-context.jarcontains the spring-context-3.0.xsd. (see spring-context.jar/META-INF/spring.schema)
Spring XDS 是随 Spring jar 定义和提供的！例如spring-context.jar包含spring-context-3.0.xsd. （见spring-context.jar/META-INF/spring.schema）
So check that you have this jar in your project.
因此，请检查您的项目中是否有这个 jar。
So what you called "remote" is not really remote! And I have never see what you called "local access", so I would try to check why the "remote" (that is not remote) stuff works for all xsds but the spring-context.
所以你所说的“远程”并不是真正的远程！而且我从来没有看到你所谓的“本地访问”，所以我会尝试检查为什么“远程”（不是远程）的东西适用于所有 xsd，但弹簧上下文。
If it is a desktop program and you use a single jar that contains all the other exploded jars, then you need a to take care that the content of the single spring.handlersand spring.schamesfiles from the different spring-xxx.jar is COMBINED in (two) "hunge" files. So that in the end this (two) files contains all the schema names and handler names.
如果它是一个桌面程序，并且您使用一个包含所有其他爆炸 jar 的单个 jar，那么您需要注意单个spring.handlers和spring.schames来自不同 spring-xxx.jar 的文件的内容在（两个）中合并”饥饿”文件。所以最终这（两个）文件包含所有模式名称和处理程序名称。

Its true that the SPRING XSD's are shipped along with the jars.
确实，SPRING XSD 与罐子一起发货。
The information where these XSD's are stored :
存储这些 XSD 的信息：
Lets say in the XML file, we have used beans namespace and we need to look into
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsdPlease check the file "spring-schemas" spring-beans-4.0.1.RELEASE.jar in META-INF folder. Sample context from this file should be:
http\://www.springframework.org/schema/beans/spring-beans-4.0.xsd =org/springframework/beans/factory/xml/spring-beans-4.0.xsd http\://www.springframework.org/schema/beans/spring-beans.xsd =org/springframework/beans/factory/xml/spring-beans-4.0.xsdThus
http\://www.springframework.org/schema/beans/spring-beans.xsd is mapped to org/springframework/beans/factory/xml/spring-beans-4.0.xsdin your jar
让我们说在 XML 文件中，我们使用了 beans 命名空间，我们需要查看
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd请检查 META-INF 文件夹中的文件“spring-schemas”spring-beans-4.0.1.RELEASE.jar。此文件中的示例上下文应为：
http\://www.springframework.org/schema/beans/spring-beans-4.0.xsd =org/springframework/beans/factory/xml/spring-beans-4.0.xsd http\://www.springframework.org/schema/beans/spring-beans.xsd =org/springframework/beans/factory/xml/spring-beans-4.0.xsd因此
http\://www.springframework.org/schema/beans/spring-beans.xsd is mapped to org/springframework/beans/factory/xml/spring-beans-4.0.xsd在你的罐子里

try run wget http://www.springframework.org/schema/context/spring-context-3.0.xsd.
尝试运行 wget http://www.springframework.org/schema/context/spring-context-3.0.xsd。
should be something like: wget http://www.springframework.org/schema/context/spring-context-3.0.xsd

If you have a problem with getting xsd schema, it makes difficult to work with xml files inherited this schema.
如果您在获取 xsd 模式时遇到问题，则很难处理继承此模式的 xml 文件。
In second case you simply don't have in classpath any of spring-*-3.0.xsd files.
在第二种情况下，您在类路径中根本没有任何 spring-*-3.0.xsd 文件。
