I think of it before reading the source code when the spring, corresponding to each xml namespace, spring requires a NamespaceHandler, such as Context needs ContextNamespaceHandler.
Do you want to modify the jar spring.handlers / spring.schemas file? Check the spring-context-5.1.5.RELEASE \ META- INF \ spring.handlers, found normal

http\://www.springframework.org/schema/context=org.springframework.context.config.ContextNamespaceHandler
http\://www.springframework.org/schema/jee=org.springframework.ejb.config.JeeNamespaceHandler
http\://www.springframework.org/schema/lang=org.springframework.scripting.config.LangNamespaceHandler
http\://www.springframework.org/schema/task=org.springframework.scheduling.config.TaskNamespaceHandler
http\://www.springframework.org/schema/cache=org.springframework.cache.config.CacheNamespaceHandler

 

Suddenly I thought, dubbo-jar are not introduced it!

        <dependency>
            <groupId>org.apache.dubbo</groupId>
            <artifactId>dubbo</artifactId>
            <version>2.7.1</version>
        </dependency>

Adding just fine!

summarize

This problem is usually caused due to an upgrade, especially after some jar before the upgrade is not compatible with the version will appear.
But Spring is very intimate, the old version of the XSD files are all put. This can prevent the escalation of the Spring version, and configuration file or use an older version of the XSD file, and then off the net, the application will not start.

I saw spring-context-5.1.5.RELEASE \ META-INF \ spring.schemas After unpacking dubbo jar:

Visible, basically everything. But only a xsd:

 

So, if the new jar, and then the old xml configuration namespace, you will still go to download xsd. download
