Dubbo: 2.6.1的demo程序报错

[daanhan]

2.6.1版本的dubbo-demo，在eclipse中运行dubbo-demo-provider里的Provider，得到以下错误，请解决，谢谢！
由于是dubbo新手，暂时猜测是xmlns:dubbo的路径问题。

It goes normal when change
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:dubbo="http://dubbo.apache.org/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-4.3.xsd http://dubbo.apache.org/schema/dubbo http://dubbo.apache.org/schema/dubbo/dubbo.xsd">
to
<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-4.3.xsd http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd">

The latest dubbo-demo codes should work with 2.6.2+, if you are using latest demo with 2.6.1, you need to register a name space handler manually in the demo code:

You can manually register the NamespaceHandler by adding META-INF/spring.handlers with the following content:

http\://dubbo.apache.org/schema/dubbo=com.alibaba.dubbo.config.spring.schema.DubboNamespaceHandler
