本文主要是介绍[Dubbox异常] Unable to locate Spring NamespaceHandler for XML schema namespace [http://dubbo.apache[,希望对大家解决编程问题提供一定的参考价值,需要的开发者们随着小编来一起学习吧!
前言
- 异常
org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Unable to locate Spring NamespaceHandler for XML schema namespace [http://dubbo.apache.org/schema/dubbo]
Offending resource: class path resource [provider.xml]
- 配置文件
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"xmlns="http://www.springframework.org/schema/beans"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.2.xsdhttp://dubbo.apache.org/schema/dubbo
http://dubbo.apache.org/schema/dubbo/dubbo.xsd"><dubbo:application name="userprovider" owner="yanxml" organization="yanxml" /><dubbo:registry address="zookeeper://127.0.0.1:2181" /><dubbo:monitor protocol="registry" /><dubbo:protocol name="rest" port="9999" contextpath="services"server="tomcat" />
<!--配置服务提供者的接口信息--><dubbo:service interface="com.yanxml.arsenal.java.dubbox.provider.http.remould.service.IHelloControllerProvider"ref="helloControllerProvider" protocol="rest" /><bean id="helloControllerProvider" class="com.yanxml.arsenal.java.dubbox.provider.http.remould.service.HelloControllerProvider" />
</beans>
- 一开始我以为异常是因为
spring
的xsd
文件版本与本地版本不一致导致的.
spring-beans-2.0.xsd
改成spring-beans-4.2.xsd
并不起效果。
Unable to locate Spring NamespaceHandler for XML schema namespace
- 后来才发现是
dubbo
的xsd
文件导致.
将http://dubbo.apache.org/schema/dubbo
改造http://code.alibabatech.com/schema/dubbo
即可解决问题.
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"xmlns="http://www.springframework.org/schema/beans"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.2.xsdhttp://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd"><dubbo:application name="userprovider" owner="yanxml" organization="yanxml" /><dubbo:registry address="zookeeper://127.0.0.1:2181" /><dubbo:monitor protocol="registry" /><dubbo:protocol name="rest" port="9999" contextpath="services"server="tomcat" />
<!--配置服务提供者的接口信息--><dubbo:service interface="com.yanxml.arsenal.java.dubbox.provider.http.remould.service.IHelloControllerProvider"ref="helloControllerProvider" protocol="rest" /><bean id="helloControllerProvider" class="com.yanxml.arsenal.java.dubbox.provider.http.remould.service.HelloControllerProvider" />
</beans>
原因
- 一开始也挺疑惑的. 因为xsd文件是可以访问到的.
- 后来经过看别人博客提醒发现. 本地使用的
dubbo
内的xsd
问题在于: dubbo-config-spring-2.6.1.jar --> META-INF–>spring.handlers 中的配置还是之前的域名 code.alibabatech.com , 而现在在github上下载的dubbo 代码里面却是: dubbo.apache.org 被坑了吧…
域名都是code.alibabatech.com
. 这个应该都是alibaba
的内部域名. 所以我们外部也无法访问。
所以, 我们一般使用本地Eclipse导入xsd文件的方式解决这个问题。
