Spring通过XML整合dubbo的过程控制台包如下错误：

Configuration problem: Unable to locate Spring NamespaceHandler for XML schema namespace \[http://dubbo.apache.org/schema/dubbo\]

配置如下：

<?xml version="1.0" encoding="UTF-8"?> 
    <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:dubbo="http://dubbo.apache.org/schema/dubbo" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.3.xsd http://dubbo.apache.org/schema/dubbo http://dubbo.apache.org/schema/dubbo/dubbo.xsd"> 
    <dubbo:application name="hello-world-app" /> 
    <dubbo:registry address="multicast://224.5.6.7:1234" />
     <dubbo:protocol name="dubbo" port="20880" /> 
    <dubbo:service interface="com.alibaba.dubbo.demo.DemoService" ref="demoServiceLocal" /> <dubbo:reference id="demoServiceRemote" interface="com.alibaba.dubbo.demo.DemoService" /> </beans>

最后发现从[http://dubbo.apache.org/zh-cn/docs/user/configuration/xml.html][http_dubbo.apache.org_zh-cn_docs_user_configuration_xml.html]网站复制的有问题

将 http://dubbo.apache.org/schema/dubbo/dubbo.xsd

上面配置为这个一直报错，改为以下

http://code.alibabatech.com/schema/dubbo/dubbo.xsd

正确配置：

<table> 
 <tbody> 
  <tr> 
   <td>&lt;?xml version="1.0" encoding="UTF-8"?&gt;<br> &lt;beans xmlns="http://www.springframework.org/schema/beans"<br> &nbsp;&nbsp; &nbsp;xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"<br> &nbsp;&nbsp; &nbsp;xsi:schemaLocation="http://www.springframework.org/schema/beans&nbsp;<br> &nbsp;&nbsp; &nbsp;http://www.springframework.org/schema/beans/spring-beans.xsd&nbsp;<br> &nbsp; &nbsp; &nbsp;http://code.alibabatech.com/schema/dubbo<br> &nbsp;&nbsp; &nbsp; http://code.alibabatech.com/schema/dubbo/dubbo.xsd"&gt;</td> 
  </tr> 
 </tbody> 
</table>
